Achates Power wins $9M from ARPA-E to develop gasoline compression ignition medium-duty multi-cylinder opposed-piston engine
November 24, 2015
Achates Power, the developer of a family of two-stroke compression-ignition opposed-piston engines (earlier post), has been selected by APRA-E under its OPEN 2015 solicitation (earlier post) for an award of more than $9 million to develop a multi-cylinder opposed piston engine operating with compression ignition that uses gasoline as the fuel.
The unthrottled nature of the compression ignition process provides high engine efficiency while achieving compliant exhaust emissions with conventional, low-cost aftertreatment. This—in addition to the opposed engine architecture—could increase fuel efficiency by 40-50% over the comparable spark-ignited gasoline engine, Achates said.

ICCT benchmarking report finds wide 51% gap between most- and least- fuel-efficient transatlantic airlines
November 17, 2015
The gap between the most- (Norwegian Air Shuttle) and least- (British Airways) fuel-efficient airlines on 2014 transatlantic operations was 51%—roughly twice the performance gap between the best and worst US airlines on domestic operations (25% in 2014), according to a newly released study by the International Council on Clean Transportation (ICCT). The new report is an extension of ICCT’s work benchmarking US airline fuel efficiency on domestic operations since 2010 (earlier post).
The gap in carbon intensity on international flights is larger than expected, which holds implication for ongoing efforts by policymakers to constrain emissions growth.
New Ford Escape launching with two new EcoBoost engines with standard Auto Start-Stop
The new Ford Escape, being showcased at the Los Angeles Auto Show, is the first Ford vehicle to make Auto Start-Stop standard with either of two EcoBoost engines new to the model—a 1.5-liter and 2.0-liter twin-scroll.
The start-stop technology senses when the vehicle is sitting idle and shuts off the engine to conserve fuel, resulting in a 4 percent to 6 percent improvement in fuel economy in stop-and-go traffic. The engine restarts automatically—in less than half a second—when the driver releases the brake pedal.

Report finds road transportation sector in Canada likely to fall far short of 2050 GHG emissions reduction target
November 12, 2015
A new Conference Board of Canada report finds that Canada is unlikely to achieve an 80% reduction in greenhouse gas emissions from 1990 levels by 2050. Even when taking into account reduced distances traveled per vehicle, improvements in fuel efficiency, and greater market penetration of alternative technology vehicles, Canada falls short of the 80-by-50 target.
Despite voluntary and regulatory initiatives that have improved the emissions efficiency of passenger and freight transportation, emissions from road transportation are increasing due to growing number of cars on the road and Canadians’ changing preference for light trucks. Canada’s road transport emissions were 40% higher in 2013 than in 1990. Between 1990 and 2013, transportation emissions accounted for nearly half of the growth of Canada’s total emissions levels, with road transport accounting for the largest share of transportation emissions.

VW uncovers irregularities in type-approval CO2 levels affecting about 800K vehicles as part of diesel investigation
November 03, 2015
The Volkswagen Group announced today that during the course of its internal investigation into the diesel emission cheating issue, it uncovered “irregularities” when determining type-approval CO2 levels. Based on present knowledge, around 800,000 vehicles from the Volkswagen Group could be affected, the company said.
Under the ongoing review of all processes and workflows in connection with diesel engines, Volkswagen investigators established that the CO2 levels—and thus the fuel consumption figures—for some models were set too low during the CO2 certification process. The majority of the vehicles concerned have diesel engines.
ICCT updates US airline fuel efficiency rankings; Alaska stays on top, American on bottom
October 22, 2015
The International Council on Clean Transportation (ICCT) has released its annual update on the fuel efficiency of US airlines. (Earlier post.) The report, which covers US airlines in domestic operations in 2014, highlights a continuing gap in the carbon intensity of US carriers, and comes as the International Civil Aviation Organization (ICAO) meets in Montreal to debate proposals that will serve as the basis for future US regulation.
The ICCT team found that the gap between most- and least-efficient airlines has narrowed slightly to 25%, and overall industry fuel efficiency has improved by 1.7% on an RPM (revenue passenger miles) per fuel basis, due in large part to a 1% increase in average passenger load factor to 84% in 2014and higher seating densities (and greater passenger discomfort) on domestic flights.
New efficient hybrid optimization control method for diesel engine emissions and performance
October 19, 2015
Researchers at Iowa State have developed a new hybrid optimization control method to improve diesel engine emissions and performance. As reported in a paper in the International Journal of Engine Research, the hybrid method, which combines both particle swarm optimization (PSO) and genetic algorithm (GA) methods was able to locate a narrow window of operation which showed 27% lower NOx emissions and 60% lower particulate matter emissions than a standard PSO method.
The hybrid method was also able to locate the improvements using similar dynamometer time, indicating that the hybrid method is more efficient and more effective, the researchers said.
EPA: jatropha-based biofuels could qualify as biomass-based diesel or advanced biodiesel under RFS
Based on its analysis of the production and transport components of the lifecycle greenhouse gas emissions of biofuel made from jatropha oil, the US EPA anticipates that biofuels produced from jatropha oil could qualify as biomass-based diesel or advanced biofuel under the Renewable Fuel Standard program if typical fuel production process technologies or process technologies with the same or lower GHG emissions are used. EPA has published its analysis in the Federal Register and is inviting comment.
Background. The RFS regulations lists three critical components of an approved fuel pathway: (1) Fuel type; (2) feedstock; and (3) production process. EPA uses lifecycle analysis to assess the overall greenhouse gas (GHG) impacts of a fuel throughout each stage of its production and use.

The company’s first car on CMA is expected to be launched in 2017. CMA’s introduction in 2017 means that all future Volvo cars will be built on just two fully scalable and wholly modular vehicle architectures.
The company also announced its electrification strategy in which plug-in hybrids will be introduced across its entire range. Volvo Cars will also develop an entirely new range of electrified smaller cars and build a fully electric car for sale by 2019.
Toyota announces aggressive environmental targets through 2050; cutting new vehicle CO2 by 90% compared to 2010
October 14, 2015
Addressing key global environmental issues such as climate change, water shortages, resource depletion, and degradation of biodiversity, the Toyota Environmental Challenge 2050 aims to reduce the negative impact of manufacturing and driving vehicles as much as possible. The challenge comprises six individual challenges across three areas: Ever-better cars, quantified as reducing global average new-vehicle CO2 emissions by 90% by 2050 compared to Toyota’s 2010 global average; ever-better manufacturing (zero CO2 emissions at all plants by 2050); and enriching the lives of communities.
As a key step toward achieving these long-term targets, Toyota is announcing its Sixth Toyota Environmental Action Plan, which will be enacted between April 2016 and the end of March 2021.
Toyota details powertrain advances in Gen4 Prius; available E-Four system for all-wheel drive (not for US)
October 13, 2015
Toyota made significant improvements in its new generation full hybrid powertrain applied in the fourth generation Prius (earlier post), reducing losses, redesigning and relocating key components and reducing weight. Extensive changes to the transaxle, engine and combined hybrid system, generate an expected improvement in EPA estimated MPG on core models of up to 10% (i.e., up to ~55 mpg US combined), with an Eco model that will achieve an even greater improvement.
In a presentation outlining the changes to the new Prius system, Shunsuke Fushiki from Toyota’s Hybrid Engineering Management Division noted that the new engine contribues about 28% of the improvement in fuel efficiency; hybrid system management contributes about 26%; the new electric motor, 16%; new transaxle and PCU, 13% each; and new battery packs, 4%.
Argonne study finds lightweight material substitution increases vehicle-cycle GHGs, but results in total life-cycle benefit
October 12, 2015
A team at Argonne National Laboratory has taken a closer look at vehicle-cycle (all processes related to vehicle manufacturing) and vehicle total life-cycle (vehicle-cycle plus fuel cycle—i.e., the use phase) impacts of substituting lightweight materials into vehicles.
In a study published in the ACS journal Environmental Science & Technology, they reported that while material substitution can reduce vehicle weight, it often increases vehicle-cycle greenhouse gas emissions GHGs—for example, replacing steel with wrought aluminum, carbon fiber reinforced plastic (CRFP), or magnesium increases the vehicle-cycle GHGs. However, lifetime fuel economy benefits often outweigh the vehicle-cycle, resulting in a net total life-cycle GHG benefit, they found. This is the case for steel replaced by wrought aluminum in all assumed cases, and for CFRP and magnesium except for high substitution ratio and low fuel reduction value.
MIT study finds carbon prices more cost-effective than fuel economy regs at reducing CO2 emissions; fuel economy regs more efficient at reducing fuel use
Researchers at the MIT Joint Program on the Science and Policy of Global Change have compared the worldwide economic, environmental, and energy impacts of currently planned fuel economy standards (extended to the year 2050) with those of region-specific carbon prices designed to yield identical CO2 emissions reductions.
Their study, which appears in the Journal of Transport Economics and Policy, finds that such stringent fuel economy standards would cost the economy 10% of global gross domestic product (GDP) in 2050, compared with a 6% cost under carbon pricing. This finding reinforces economists’ contention that improving the efficiency of motor vehicles through fuel economy standards will yield significantly less CO2 emissions reduction per dollar than an economy-wide instrument that encourages such cutbacks where they are cheapest—principally in the electric power and industrial sectors.

ICCT update finds real-world vehicle fuel economy gap continues to widen in Europe to 40%
The gap between official fuel-economy figures and the real world for new cars in the EU has reached 40 per cent, according to the latest update by the International Council on Clean Transportation (ICCT) to its on-going research into in-use vehicle fuel efficiency and CO2 emissions. (Earlier post.)
Since 2001, the discrepancy between official measurements of vehicle efficiency and actual performance of new cars in everyday driving has more than quadrupled—a discrepancy that now translates into €450 (US$500) per year in extra fuel costs for the average vehicle. The updated study closely follows on revelations that a similar gap in NOx emissions from diesel passenger vehicles was, at least in the case of Volkswagen, deliberately engineered, and as the European Commission prepares to adopt an improved test procedure that would produce more realistic vehicle test results.

Jaguar Land Rover investigating energy-efficient vehicle heating and cooling; Air Bubbles and Air Blankets
September 10, 2015
Because heating, ventilation and air conditioning systems (HVAC) consume substantial amounts of energy—and therefore fuel, or electrical energy stored in the battery of a Battery Electric Vehicle (BEV)—Jaguar Land Rover (JLR) is working on research projects that could significantly reduce the energy consumed when heating and cooling a vehicle.
Rather than continuously heating or cooling a flow of air as it enters the car, Jaguar Land Rover is exploring how a car could heat or cool an “Air Bubble” inside the vehicle once, and then maintain the temperature and quality of this air bubble using innovative new HVAC technologies. These include infra-red reflective (IRR) glass, tailor-made for the solar radiation profile of an individual region or country. The glass would reflect the sun’s rays so less energy is required to cool the inside of the car.
Achates Power proposes EPA/NHTSA medium- and heavy-duty engine standard require 15% decrease in fuel consumption and emissions
Achates Power, Inc., the developer of a family of efficient compression-ignition opposed-piston two-stroke (OP2S) engines (earlier post), proposed more stringent engine fuel efficiency and emission standards for medium- and heavy-duty vehicles at a recent public hearing held by the National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency (EPA) on “Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles – Phase 2”.
Earlier this year, NHTSA and EPA jointly announced the proposed Phase 2 standards for medium- and heavy-duty vehicles. (Earlier post.) While these vehicles as a whole will have to curb fuel consumption and carbon dioxide emissions by up to 24% between the 2018 and 2027 model years, the agencies are proposing separate engine standards requiring only a 4% decrease.

(Earlier post.) The CLEEN team focused on nine projects in the area of energy efficient aircraft technologies and sustainable alternative jet fuels. The first of these technologies will enter service in 2016.
New Tandem Axle Lift function from Volvo Trucks lowers fuel consumption up to 4%
Volvo Trucks has introduced a new function—Tandem Axle Lift—that makes it possible to disengage and raise the second driven axle even while driving. This gives better road grip and up to 4% lower fuel consumption when the truck is driven without a load. The new function is designed for heavy duty transports with loads being carried one way and empty return trips—for example, when hauling timber or in construction and bulk cargo operations.
By replacing the differential in the first driven axle with a dog clutch, the second driven axle can be disengaged and raised; the tires can be lifted 140mm (5.51 inches) off the road surface. The driver thus has access to both the power and capacity of two driven axles (6X4) and also the better maneuverability of a single driven axle (4X2).
Bosch presenting new heat pump EV thermal management system at IAA; up to 25% increase in effective range
September 08, 2015
At IAA next week, automotive supplier Bosch is presenting a new heat-pump-based thermal management system for EVs that it says can enable an increase in effective range of up to 25% without modifications to the battery.
In battery-driven powertrains, heating and cooling can play a significantly greater role than in gasoline or diesel engines, since without a combustion engine, the vehicle does not have a generous supply of heat. If the passenger compartment is heated using a purely electrical system drawing its power from the battery, range can be significantly reduced. As a result, there has been interest in the industry about the use of heat pumps as a lower energy-intensity solution.

The partnership with Heriot-Watt University will initially focus on delivering the £1.5-million (US$2.3-million) National Scheduling Platform project—an on-demand route optimization and scheduling solution that can be easily accessed via a web portal.
This integrated mobility platform is intended to enable the efficient transportation of people and goods in ways that deliver the maximum economic, environmental and societal benefits. Funded in conjunction with Scottish Enterprise and Transport Scotland, the platform is due to go live next year.
New engines in Porsche 911 Carrera boost power and torque; almost 12% more efficient
The new Porsche 911 Carrera features a set of new engines that increase power and torque while also decreasing fuel consumption. The completely new engine generation with bi-turbo charging offers 370 hp (272 kW) at the rear of the 911 Carrera and 420 hp (309 kW) in the 911 Carrera S. In both cases this represents a power increase of 20 hp (15 kW). Both engines have a displacement of three liters.
Every new 911 generation boasts enhanced performance and efficiency compared with the predecessor. For example, depending on the model variant, the new engine generation is almost 12% more efficient: fuel consumption is reduced by up to a liter per 100 kilometers. The 911 Carrera with PDK transmission now consumes 7.4 liters of fuel per 100 kilometers (32 mpg US), a reduction of 0.8 l per 100 km, while the 911 Carrera S with PDK consumes 7.7 l/100 km (31 mpg US)—1.0 l less per 100 km.
ICCT: industry lagging UN fuel efficiency goals for new commercial aircraft by about 12 years; need for a CO2 standard
September 03, 2015
Reductions in the average fuel burn of new commercial aircraft have returned to the long-term average after stagnating from 2000 to 2010. However, according to a new report from the International Council on Clean Transportation (ICCT), manufacturers continue to lag the UN’s fuel efficiency goals for new aircraft; on average, industry is about 12 years behind the 2020 and 2030 aspirational goals established by the International Civil Aviation Organization (ICAO).
The authors of the ICCT report, which updates its 2009 report on the topic (earlier post), do expect to see an accelerating improvement rate in the foreseeable future due to the introduction of new, more efficient aircraft designs such as the a320neo, 737 MaX, and 777X. Despite that, when comparing the ICAO fuel burn technology goals (a 40% improvement in fuel efficiency for new single-aisle (SA) and small twin-aisle (STA) aircraft in 2020 relative to 2000 levels) with fuel burn trend projections, they found the 12-year time lag between the projected fuel burn improvement and the time needed to reach ICAO’s goals.
FCA US upgrades 3.6L Pentastar V-6; 2-step VVL, cooled EGR; up to 6% better fuel economy
September 02, 2015
FCA has upgraded its 3.6-liter Pentastar engine for MY 2016. The 3.6L Pentastar, first introduced in 2009 (earlier post), was the first of an all-new line of V-6 engines intended to improve fuel efficiency across the Chrysler, Jeep and Dodge lineup. More than 5 million Penetastar engines are now on the road.
Depending on the application, the redesigned V-6 delivers fuel-economy improvements of more than 6% while increasing torque more than 14.9%. This occurs at engine speeds below 3,000 rpm, where elevated torque has its most profound impact on the driving experience. Enhancements such as two-step variable valve lift (VVL), cooled exhaust-gas recirculation (EGR) and innovative weight-reduction strategies boost the engine’s efficiency and performance, all while preserving its smoothness.

New Opel Astra up to 441 lbs lighter than predecessor
August 27, 2015
The new Opel Astra, which makes its debut in several weeks at the IAA in Frankfurt, will be up to 200 kg (441 lbs) lighter than its predecessor (120 kg / 265 lbs at a minimum). The next generation of the compact bestseller is based on an all-new lightweight architecture, with a slimmer body and all-aluminum engines.
The Monza Concept presented at the 2013 IAA (earlier post) was the role model for Opel’s eleventh compact class generation. The new Astra features a slimmed down vehicle architecture: the bodyshell (body-in-white) and structure alone are more than 20 percent lighter, down from 357 to 280 kilograms (787 to 617 lbs). Another 50 kilograms (110 lbs) were saved in the design of chassis components: high-strength and ultra-high-strength lightweight steels, more compact subframes as well as modification to the front and rear suspensions all contributed to this end result.
Renault Trucks and partners launch EDIT project to cut distribution vehicles’ fuel consumption by 13%
After Optifuel Lab 2 (earlier post), the laboratory vehicle which brought together technological innovations designed to reduce long-distance trucks’ fuel consumption, Renault Trucks is extending its research to distribution vehicles.
Renault Trucks and six partners—Valeo, Lamberet, Michelin, BeNomad, INSA de Lyon (LamCoS) and IFSTTAR (LICIT)—have launched the EDIT (Efficient Distribution Truck) project, which aims to reduce distribution vehicles’ fuel consumption by 13% compared with a current production vehicle.
FEV working on water injection system using exhaust condensate; fuel consumption improvements up to 16% possible
August 26, 2015
FEV is developing a water injection system for internal combustion engines using condensate from exhaust gases, the “Extended Direct Condensate Injection” system. The concept, as reported in a new paper in the International Journal of Engine Research , demonstrates a potential for efficiency increase of 3.3% – 3.8% in the region of the minimum specific fuel consumption on a stoichiometric combustion concept with Miller cycle and cooled external exhaust gas recirculation.
Further improvement of the efficiency of up to 16% is possible at full-load operation, the researchers said. If water injection is used in addition to homogeneous lean combustion, an efficiency gain of 4.5% in the region of the minimum specific fuel consumption is achieved.
Team from GM, Ford, FCA reviews how to calculate engine efficiency benefits of high octane fuels
August 25, 2015
A team of engineers from GM Powertrain, Ford and FCA have published a detailed review of how to estimate the engine efficiency benefits of higher octane fuel—e.g., fuel with higher ethanol content—for part- and full-load operation for different engine types and fuel assumptions. Their paper is published in the ACS journal Environmental Science & Technology.
Engine compression ratio plays a fundamental role in engine efficiency; a higher compression ratio improves efficiency, but also causes higher temperatures and pressures of the unburned air-fuel mixture which can lead to knock at high loads. Compression ratio is thus limited to avoid knock. The compression ratio selected for a particular engine depends, the authors note, on the expected duty cycle and fuel octane. A higher compression ratio can be used if an engine will operate primarily at light loads, such that degraded efficiency at high loads is more than offset by improved efficiency at light loads.
CMU analysis finds BEVs powered with natural gas-based electricity have about 40% of the lifecycle GHGs of a conventional gasoline vehicle
August 21, 2015
According to a new lifecycle analysis by a team at Carnegie Mellon University, a battery electric vehicle (BEV) powered with natural gas-based electricity achieves around an average 40% lifecycle greenhouse gas (GHG) emissions reduction when compared to a conventional gasoline vehicle. Plug-in hybrids (PHEVs), either with a 30- or 60-km range, when powered by natural gas electricity, have the second lowest average emissions. Both BEVs and PHEVs provide large (more than 20%) emissions reductions compared to conventional gasoline, but none of them is a dominant strategy when compared to gasoline hybrid electric vehicles (HEVs), the team found.
Gaseous hydrogen fuel cell electric vehicles (FCEVs) and compressed natural gas (CNG) vehicles have comparable life cycle emissions with conventional gasoline, offering limited reductions with 100-year global warming potential (GWP) yet leading to increases with 20-year GWP. Other liquid fuel pathways using natural gas—methanol, ethanol, and Fischer–Tropsch liquids—have larger GHG emissions than conventional gasoline even when carbon capture and storage technologies are available. The study is published in the ACS journal Energy & Fuels.
New UMTRI report on US vehicle fuel economy from 1923-2013 suggests need to focus on improving lower tails in each vehicle class
August 17, 2015
In a new report, researchers at the University of Michigan Transportation Research Institute (UMTRI) have calculated the actual, on-road fuel economy for the entire fleet of all vehicles in the US, and for different classes of vehicles, with primary interest in light-duty vehicles (cars, pickup trucks, vans, and SUVs), between 1923 and 2013.
The main findings from the analysis are that fuel economy decreased from 14.0 mpg (16.8 l/100 km) in 1923 to 11.9 mpg (19.6 l/100 km) in 1973. Starting in 1974, fuel economy increased rapidly to 16.9 mpg (13.9 l/100 km) in 1991. Thereafter, improvements have been small, with fuel economy in 2013 at 17.6 mpg (13.4 mpg US). Overall, the results suggest, the authors conclude, that efforts on improving fuel economy should focus on the lower tails of the distributions of fuel economy in each vehicle class.

The 200 hp variant is available on Limited specification while the 185 hp is fitted on Cherokee Longitude and Longitude+ variants only. The engines are available only with Jeep’s segment-first nine-speed automatic gearbox, and are matched to the Active-Drive four-wheel-drive systems.
Tsinghua studies on alcohol-gasoline dual fuel engines show fuel efficiency and particle number benefits
August 10, 2015
Researchers at Tsinghua University in China are studying the effects of Dual-Fuel Spark Ignition (DFSI) combustion fueled with different alcohols and gasoline. In one paper, published in the journal Fuel, they investigated the use of alcohols–gasoline DFSI Combustion for knock suppression and high fuel efficiency using a gasoline engine with high compression ratio.
In a second paper, also published in Fuel, they systematically compared the stoichiometric alcohol–gasoline and gasoline–alcohol DFSI combustion for engine particle number (PN) reduction (and fuel economy improvement), also using a high compression ratio gasoline engine.
Ford wins 3rd annual Altair Enlighten Award for lightweighting of F-150
August 07, 2015
Ford Motor Company was the winner of the 3rd annual Altair Enlighten Award for its use of various lightweight materials to minimize weight of the 2015 Ford F-150. The Enlighten Award is the automotive industry’s first award program created specifically to acknowledge innovation in vehicle weight reduction.
Ford’s entry, one of 17 nominations that competed for the award, was selected as the winner for taking 700 pounds (318 kg) off of the Ford F-150 while improving its performance, safety, and efficiency. (Earlier post.) Ford engineers took a holistic approach to weight reduction by incorporating advanced materials into the entire design of the vehicle, including the frame, body, powertrain, battery and interior features such as the seats. The weight savings help the truck tow more, haul more, accelerate quicker and stop shorter, and it contributes to fuel efficiency.
VW bringing EA211 1.4L turbo direct-injection engine to Jetta range in US
August 04, 2015
Volkswagen is introducing the 1.4-liter EA211 four-cylinder turbocharged and direct-injection TSI engine into the Jetta range, replacing the previous naturally aspirated 2.0-liter engine that was used in the S model and the 1.8T TSI engine in the SE model. This brings implementation of intelligent downsizing to more than 97% of vehicles sold by Volkswagen in the US, available across all the models on sale.
The engine will be mated to either a five-speed manual or a six-speed automatic transmission: manufacturer estimated fuel economy on the highway is predicted to be 39 mpg with the six-speed automatic transmission, an improvement of 13% over the EPA estimated highway fuel economy for the previous 2.0-liter engine and 7% over the 1.8T.
2016 Chevrolet Volt EPA-rated at 53 miles all-electric range
The Chevrolet Volt’s all-new second-generation Voltec extended-range electric propulsion system (earlier post) delivers 53 miles (85 km) of all-electric range, based on EPA testing. That is nearly a 40% improvement over the first-generation Volt, and a 6% boost over the projected 50-mile (80 km) AER estimated at the new Volt’s unveiling in January. (Earlier post.)
Chevrolet expects many next-generation Volt owners will use power solely from their batteries for more than 90% of trips. Today, Volt owners use battery power on 80% of their trips, according to GM. The additional range would enable the average Volt owner to travel well over 1,000 miles (1,609 km) (in multiple trips) between gas fill ups, if they charge regularly.
Researchers find HEV under real-world conditions delivers significantly greater fuel economy benefits than EPA “sticker” values
August 03, 2015
In a new study reported in the ACS journal Environmental Science & Technology, a team at the University of Vermont found that when including real-world road grade and ambient conditions compared to controlled laboratory tests, fuel consumption benefits for a hybrid electric vehicle (HEV) under study increased by 18% highway and 33% city compared to estimates based on EPA adjusted fuel economy “sticker” values. (The vehicles under study were a conventional and hybrid Camry).
In other words, they found that they real-world fuel economy benefit of adoption of HEVs may be better than for estimates based on EPA “sticker” fuel economy alone. The duo, Britt A. Holmén and Karen M. Sentoff, suggested that based on these results, more positive forecasts for future petroleum and corresponding CO2 emissions savings from increased hybridization of the passenger vehicle fleet may be warranted.
Aeristech launches new 48V electric supercharger
July 31, 2015
UK-based Aeristech has introduced a new 48V electric supercharger capable of continuous operation at high boost levels. Independently validated by Ricardo and MAHLE Powertrain UK, the technology provides greater efficiency and easier packaging than a mechanical supercharger or a two-stage turbocharger.
Aeristech said it overcame the thermal management issues that can restrict other electric boosting devices currently available on the market to only transient operation by using permanent magnet motor technology in place of the more usual switched reluctance type. This has been made cost-effective by developing a patented control and switching technology that enables the use of many cost-competitive components.
Delphi invests in Tula; Dynamic Skip Fire cylinder deactivation
July 30, 2015
Delphi has made a minority investment in Tula Technology, the developer of Dynamic Skip Fire cylinder deactivation technology. (Earlier post.) The software-enabled powertrain technology integrates advanced digital signal processing with advanced powertrain controls to create a variable displacement engine.
DSF allows the engine’s cylinders to fire or skip (deactivate) on a continuously variable basis. In independent tests, DSF has improved fuel efficiency by up to 17% as measured on a CAFE basis when compared to a vehicle (V8 engine) that does not have cylinder deactivation. GM Ventures made an equity investment in Tula in 2012.
Chevrolet introduces Colorado Duramax Diesel midsize pickup
July 28, 2015
Chevrolet has introduced the diesel version (earlier post) of its 2016 Colorado midsize pickup truck. (Colorado is the 2015 Motor Trend Truck of the Year and Cars.com’s Best Pickup Truck of 2015.) With 369 lb-ft of torque (500 N·m) generated by the all-new 2.8L Duramax turbo-diesel, the Colorado’s maximum trailering capacity rises to 7,700 pounds (3,492 kg) on 2WD models, with estimated fuel economy projected by GM to top the already segment-leading efficiency of the gas models (27 mpg (8.7 l/100 km) highway with 2.5L gasoline engine and automatic transmission).
It is also the cleanest diesel truck engine ever produced by General Motors. The new Colorado diesel goes on sales this fall, offered in LT and Z71 Crew Cab models, with 2WD or 4WD. It is priced $3,730 more than a comparably equipped 3.6L V-6 model.
BMW brings Enlighten real-time signals app into car
July 27, 2015
The BMW Group is the first manufacturer to bring the EnLighten App, by Connected Signals, into the car. Drivers of BMW Vehicles with iOS Devices will be able to see traffic signal data on the vehicle’s display in real time. The EnLighten app makes driving in cities easier by helping the driver anticipate traffic signal changes, which can increase safety and help save fuel by avoiding unnecessary acceleration.
The EnLighten app shows the current status of the traffic light in front of the car in real time as well as a countdown to when the signal will change. Based on the current vehicle position, as well as its speed, the EnLighten app offers a recommendation about whether or not to stop for the traffic light or proceed through. An audio alert notifies the driver about a pending change in the signal they are approaching.

The LNGreen joint industry project brought together experts from DNV GL and industry specialists from GTT (cryogenic membrane containment systems for LNG); shipbuilder Hyundai Heavy Industries; and shipowner GasLog.
Each of the project partners contributed their know-how and experience, to develop a next-generation LNG carrier using the latest technology, within the bounds of existing shipbuilding methods. The vessel concept has a significantly improved environmental footprint; a higher level of energy efficiency (up to 8% improvement); as well as an improved boil-off rate and cargo capacity (+5%), making it much better suited to future trading patterns than existing vessels.
GM using Continental Structural Plastics’ TCA Ultra Lite in Corvette for 20 lb weight savings
July 22, 2015
Continental Structural Plastics (CSP), a global provider of lightweight composite solutions, announced that its Tough Class A (TCA) Ultra Lite material, introduced in September 2014, is now in production on the 2016 Chevrolet Corvette. The use of TCA Ultra Lite, a Class A body panel material, results in a 20 lb (9 kg) weight savings on the Stingray Coupe model. This is the first production use of CSP’s Ultra Lite advanced composite.
Ultra Lite technology uses treated glass bubbles to replace some of the CaCO3 (calcium carbonate) filler, allowing the resin to adhere to the matrix and increase the interfacial strength between the bubble and the resin. This is a patented treatment technology that results in a more robust resin mix that makes molded parts more resistant to handling damage, and prevents the micro-cracks that cause paint pops, pits and blistering. The treated bubbles also help with paint adhesion and bonding characteristics.

Researchers at the US Department of Energy’s (DOE) Argonne National Laboratory are partnering with Ford Motor Company and FCA US LLC in pre-competitive research to study blending natural gas and gasoline using natural gas direct injection to enable more efficient engines. The project is a cooperative research and development agreement (CRADA) resulting from the 2014 DOE Vehicle Technologies Office (VTO) Funding Opportunity Announcement (FOA).
The project’s objective is to understand potential benefits and demonstrate targeted blending of gasoline and natural gas in an engine that uses half as much gasoline and shows a 10% increase in overall efficiency and a 10% improvement in power density.
Volkswagen launches new Passat GTE plug-in hybrid in Europe
Volkswagen has launched its second plug-in hybrid based on a high-volume production model: the Passat GTE, available either as a sedan or Variant (wagon)—the first plug-in hybrid from Volkswagen to be sold as either. (Earlier post, earlier post.) The Passat GTE and Passat GTE Variant will arrive on the European market this autumn; in the first few countries advance sales have already begun. In Asia the launch will also be this year. In terms of the brand, the Passat GTE is a basic building block in Volkswagen’s electric motoring strategy.
Together with the plug-in hybrids from Audi (A3 e-tron, Q7 e-tron and R8 e-tron) and Porsche (Cayenne S E-Hybrid and Panamera S E- Hybrid), Volkswagen AG now has ten models in its portfolio driven wholly or partially on electric power. (The Volkswagen brand contributes the Golf and Passat GTE plug-ins, the low-volume XL1, and the battery-electric e-up! and e-Golf.) The Passat GTE is the first plug-in hybrid model being sold by the Group in the high-volume segment of large family cars.
Ford’s first mass-produced carbon fiber wheels
July 12, 2015
To source the new lightweight track-capable carbon fiber wheels that are standard on the new Shelby GT350R Mustang, Ford partnered with Australia-based Carbon Revolution. Carbon Revolution first began delivering composite wheels in 2004 for Formula SAE campaigns. The company now is producing its “CR-9” wheel series in limited numbers for Porsche, BMW M3, Audi R8, Lamborghini and McLaren MP4-12C within Europe, Japan and North America. Ford, however, wanted more of a mass-production solution.
The one-piece carbon fiber wheels for the Mustang weigh nearly half that of an equivalent aluminum wheel (18 pounds versus 33 pounds), and handling and acceleration performance see serious benefits. The wheels also provide a reduction in rotational inertia of more than 40%, which positively impacts acceleration and braking performance. The wheels are so light, the springs and MagneRide dampers had to be recalibrated because the suspension can respond considerably faster to road inputs.
UMTRI study finds total cost of ownership of diesels in US often much less than gasoline counterparts
July 09, 2015
A comprehensive study of the total cost of ownership (TCO) of light- and medium-duty diesel passenger vehicles in the US has found that the total cost of ownership—depreciation, fuel costs, repairs, maintenance, insurance, and fees and taxes—is often much less for diesel vehicles as compared to gasoline versions of the same vehicles, mostly ranging from $2,000 to $7,000 over three to five years.
Bruce Belzowski, managing director of the U-M Transportation Research Institute's Automotive Futures group, compared thousands of gasoline and diesel versions of the same or nearly identical vehicles sold at auction in 2012-13, including Audi, BMW, Mercedes-Benz and Volkswagen passenger cars and SUVs, and Chevrolet, Ram, Ford and GMC medium-duty pickup trucks.
European automakers and fuel suppliers argue for diesel as they call on policy makers to accelerate fleet renewal
July 08, 2015
In an open letter to EU policy makers, leading representatives of the automotive and petroleum refining industry in Europe called on policy makers to help accelerate fleet renewal and the introduction of the cleanest vehicles and committed to keep pushing the technical boundaries in order to find ever better ways of combining the customer benefits of diesel—fuel economy and low CO2—with continuously reduced emissions.
The associations pointed out that political measures restricting the rollout of the new generation of diesel technology would undermine existing efforts to cut CO2 emissions.
Volkswagen 2015 Golf TDI diesel tours all lower 48 states on 101.43 gallons; 81.17 mpg
A 2015 Golf TDI Clean Diesel has set a new Guinness World Records achievement for the “lowest fuel consumption—48 US contiguous States for a non-hybrid car” with an 81.17 mpg (2.9 l/100 km) performance. Traveling 8,233.5 miles (13,251 km) around the US in 16 days on $294.98 of Shell Diesel fuel, the Golf beat the previous mark of 77.99 mpg (3.01 l/100 km) by more than 3 mpg, and also beat the hybrid vehicle record of 74.34 mpg (3.16 l/10 km) by more than 6 mpg. The 2015 Golf TDI carries an EPA-estimated highway fuel economy rating of 45 mpg (5.22 l/100 km).
The record-setting Golf TDI, sporting Volkswagen of America’s 60th anniversary emblem, as well as logos from sponsors Shell, Goodyear, LG, Garmin and Linear-Logic, departed from Volkswagen of America’s headquarters in Herndon, Va., on 22 June. It returned on 7 July, having visited all 48 contiguous states.

(Earlier post.) The car achieved an average 932 miles (1,500 km) on each tank of fuel, at a total fuel cost for the whole journey of just £459 (US$716).
Behind the wheel of a Honda Civic Tourer 1.6 i-DTEC for the entire journey were two members of Honda’s European Research & Development (R&D) team, Fergal McGrath and Julian Warren, who took on the challenge to further demonstrate the real-world fuel economy of the Tourer.
Mercedes-Benz introduces next-gen OM 471 heavy-duty engine; more fuel efficient, more torque with fast build-up at very low revs
July 03, 2015
Mercedes-Benz Trucks has introduced the latest generation of its OM 471 six-cylinder, in-line heavy-duty diesel engine. The latest generation reduces fuel consumption by up to 3% while increasing torque; the new series is also spearheaded by a unit offering new top performance figures of 390 kW (530 hp) and 2600 N·m (1,918 lb-ft) of torque.
Assuming an annual mileage of 130,000 km (80,778 miles) in long-distance transport and a consumption of approx. 28.5 liters/100 km (8.25 mpg US) on a demanding route covered at full load capacity, the latest-generation OM 471 engine would save around 1100 liters (291 gallons) of fuel a year and emit about three tonnes less CO2.
Study: even with high LDV electrification, low-carbon biofuels will be necessary to meet 80% GHG reduction target; “daunting” policy implications
A study by researchers from the University of Wisconsin-Madison and a Michigan State University colleague has concluded that even with a relatively high rate of electrification of the US light-duty fleet (40% of vehicle miles traveled and 26% by fuel), an 80% reduction in greenhouse gases by 2050 relative to 1990 can only be achieved with significant quantities of low-carbon liquid fuel. The paper is published in the ACS journal Environmental Science & Technology.
For the study, the researchers benchmarked 27 scenarios against a 50% petroleum-reduction target and an 80% GHG-reduction target. They found that with high rates of electrification (40% of miles traveled) the petroleum-reduction benchmark could be satisfied, even with high travel demand growth. The same highly electrified scenarios, however, could not satisfy 80% GHG-reduction targets, even assuming 80% decarbonized electricity and no growth in travel demand.

Tire-integrated triboelectric generator harvests electricity from rolling tire friction; est. up to +10% fuel econ
June 30, 2015
A group of University of Wisconsin-Madison engineers and a collaborator from China have developed a triboelectric nanogenerator (TENG) that harvests energy from a car’s rolling tire friction. An innovative method of reusing energy, the nanogenerator ultimately could provide automobile manufacturers a new way to squeeze greater efficiency out of their vehicles.
The TENG is a novel energy harvesting device to convert mechanical energy into electricity based on the universally known triboelectric principle—i.e., the generation of an electric charge resulting from the contact or rubbing together of two dissimilar objects. Specifically, the nanogenerator relies on the triboelectric effect to harness energy from the changing electric potential between the pavement and a vehicle’s wheels.

Chevrolet will add a new clean diesel engine to the US lineup in 2017, featuring a B20-capable 1.6L diesel already proven in Europe and other global markets.
Ford assessment of two cylinder deactivation strategies for award-winning 3-cyl. EcoBoost
June 23, 2015
|A comparison of the benefits of two different cylinder deactivation operating strategies for downsized 3-cylinder engines such as the 1.0L EcoBoost. The largest difference proved to be in cost. Schamel et al. Click to enlarge.|
Ford’s 1.0-liter EcoBoost engine recently received its eighth award in four years at the 2015 International Engine of the Year Awards. The judges selected the 999cc EcoBoost as the winner (for the fourth consecutive year) in the “Sub 1-Litre” category, awarding it 444 points. The second place challenger, GM’s 999cc EcoTec 3-cylinder turbo, scored 176 points. (Although the EcoBoost received 61 fewer points than last year, the gap between first and second place widened.) Last year, the 1.0‑liter EcoBoost became the first engine to be named overall International Engine of the Year three times in a row, and was in 2012 named “Best New Engine.”
One of the judges, Hormazd Sorabjee of Autocar India said, “That so much can be achieved from a sub 1-liter, three-cylinder motor is simply astounding.” That may be, but Ford is exploring ways to further improve the fuel efficiency of the three-cylinder design, including the possible use of cylinder deactivation.

BorgWarner R2S two-stage turbo boosts performance of new top-end Ford 2.0L diesel
June 22, 2015
BorgWarner’s regulated two-stage (R2S) turbocharging technology is improving the performance and fuel economy of Ford’s new 2.0-liter TDCi diesel engine, the first Ford engine for passenger cars equipped with a two-stage turbocharging system. The high-performance engine, being offered in Mondeo, S-MAX and Galaxy models in Europe, achieves an output of 155 kW (210 PS) and a maximum torque of 450 N·m from 2000 rpm and will replace the 2.2-liter TDCi diesel engine.
BorgWarner’s R2S turbocharging technology consists of two turbochargers arranged in series to deliver improved torque and smooth power over the entire engine speed range. One compact KP35 high-pressure turbocharger generates boost pressure at low exhaust gas flow rates for rapid acceleration at low engine speeds without delay or turbo lag. As engine speed increases, the exhaust gas stream is split, and the larger K04 low-pressure turbocharger works in series with the KP35 high-pressure turbocharger.
New PSA 1.2-liter 3-cylinder turbo takes International Engine of Year category award
PSA Peugeot Citroën’s new 1.2-liter 3-cylinder Turbo PureTech engine (earlier post) was named best in the 1.0-liter to 1.4-liter category International Engine of the Year 2015 earlier this month. Some 100,000 units of the engine, which displaced the reigning category champion Volkswagen Group 1.4-liter TSI Twincharger (2014-2006) by 69 points, have already rolled off the production line at the Française de Mécanique plant in Douvrin, France.
The PureTech family of 3-cylinder engines offers high levels of performance, cutting fuel consumption and CO2 emissions by an average of 18% compared with its predecessors. The 1.0-liter and 1.2-liter naturally aspirated versions have been manufactured since 2012 at the French Trémery plant, which has an annual production capacity of 640,000 units. The 1.2-liter turbo versions have been split since 2014 between the Française de Mécanique plant and the Xiangyang plant in China, which have respective annual production capacities of 320,000 and 200,000 units.
EPA and NHTSA propose Phase 2 GHG and fuel efficiency standards for medium- and heavy-duty trucks
June 19, 2015
The US Environmental Protection Agency (EPA) and the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) are jointly proposing Phase 2 standards for medium- and heavy-duty vehicles to improve fuel efficiency and cut greenhouse gas emissions. The proposal builds on the Phase 1 fuel efficiency and GHG emissions standards already in place for model years 2014-2018. (Earlier post.)
Three years in development, the proposed Phase 2 vehicle and engine performance standards would cover model years 2021-2027, and apply to semi-trucks, large pickup trucks and vans, and all types and sizes of buses and work trucks. They would achieve up to 24% lower CO2 emissions and fuel consumption than an equivalent tractor in 2018, based on the fully phased-in standards for the tractor alone in a tractor-trailer vehicle.
NRC report finds Federal analysis to set LD CAFE and GHG standards generally of high quality; some technologies and issues should be re-examined
The analysis used by federal agencies to set standards for fuel economy (CAFE) and greenhouse gas emissions for new US light-duty vehicles from 2017 to 2025 was thorough and of high caliber overall, according to a new report from the National Research Council.
However, the report authors found, the agencies should re-examine certain issues such as consumer behavior and the effectiveness of certain technologies in an upcoming mid-term review. In addition, the report found, evidence suggests that the standards will lead the nation’s light-duty vehicle fleet to become lighter but not less safe.

US$7.5M JOSPEL project to develop energy efficient climate control for EVs; leveraging Joule and Peltier effects
June 03, 2015
A trans-European collaboration aims to develop a novel energy efficient climate control system to help reduce the energy used for passenger comfort in electric vehicles by at least 50%. Even in today’s modern electric vehicles, a lot of energy is wasted on heating or cooling, in turn limiting the already relatively short range by further draining the battery capacity.
The aim of the €6.7-million (US$7.5-million) JOSPEL project is to develop an efficient, electrical climate control system using an integrated approach that combines the application of the Joule and Peltier effects; efficient insulation of the vehicle interior; energy recovery from heat zones; increased battery life as a side effect of thermal management; reduced battery energy consumption via the integration of Peltier cooling; innovative automated and eco-driving strategies; and the electronic control of power flows.
