GM has been working closely with Tula Technology; in 2012, GM Ventures made an equity investment in Tula. (Earlier post.) In 2015, Delphi also took a stake in the Silicon Valley-based company. (Earlier post.)
Tsinghua team evaluates impact of types and arrangements of electric traction motors in fuel cell hybrid buses
April 20, 2016
Researchers at Tsinghua University have compared the performance of two different powertrains for fuel cell hybrid buses. Both buses use 50 kW PEM fuel cell stacks (from different manufacturers) as the primary power source, with LiMn2O4 battery packs as secondary power sources. A significant difference between the two powertrains lies in the types and arrangements of the electrical motor.
One powertrain employs a single induction motor (IM) to drive the vehicle via a reduction gearbox and differential (Powertrain A), while the other powertrain adopts two permanent magnetic synchronous motors (PMSMs) for near-wheel propulsion (Powertrain B). A further difference between the proposed powertrains is the supply path for the fuel cell accessories. A paper on their study is published in Journal of Power Sources.

Their paper is published in the journal Fuel.
Use of lower carbon natural gas and carbon-free hydrogen have potential to reduce harmful emissions of criteria pollutants and greenhouse gas (GHG) emissions and and could displace a portion of conventional liquid fossil fuels, the IIT noted. However, both fuels pose different challenges for use in internal combustion (IC) engines.
CMU study shows autonomous vehicle algorithms can have considerable effect on fuel economy; need for new approaches in testing
March 24, 2016
Autonomous vehicle driving behavior can have a considerable effect on fuel economy. Researchers in the College of Engineering at Carnegie Mellon University have determined that fuel efficiency for self-driving cars—within the bounds of current fuel economy testing—could improve by up to 10% under efficiency-focused control strategies when following another vehicle.
However, the study also showed that autonomous vehicle (AV) technology following algorithms designed without considering efficiency can degrade fuel economy by up to 3%. In a paper published in the journal Transportation Research Part C: Emerging Technologies, Assistant Professor of Civil & Environmental Engineering Constantine Samaras and Ph.D. student Avi Chaim Mersky suggest the need for a new near-term approach in fuel economy testing to account for connected and autonomous vehicles.

MIT Energy Initiative report on transforming the US transportation system by 2050 to address climate challenges
March 16, 2016
A new MIT Energy Initiative report spearheaded by John Heywood, Sun Jae Professor of Mechanical Engineering Emeritus at MIT, identifies three important paths forward reducing light-duty vehicle energy use and greenhouse gas emissions: improve the existing system and technologies for shorter-term benefits; conserve fuel by changing driver habits for nearer- to longer-term benefits; and transform the transportation system into one that is radically less carbon-intensive for longer-term benefits.
According to the report, “On the Road Toward 2050: Potential for Substantial Reductions in Light-Duty Vehicle Energy Use and Greenhouse Gas Emissions,” each element is separately important, but must collectively be pursued aggressively to achieve necessary emissions reductions. More research, development, and demonstration studies are needed to lay the foundation for such a long-term transformation.

MIT/CalTrans study finds pavement-vehicle interaction accounts for 1% of overall fuel consumption on California highways
March 01, 2016
A recent collaboration between the MIT’s Concrete Sustainability Hub (CSHub) and the California Department of Transportation (Caltrans) showed that phenomena associated with deflection-induced pavement-vehicle interaction (PVI) accounts for 1% of overall fuel consumption on California highways.
Deflection-induced PVI—which results from a vehicle overcoming a resisting force (i.e. dissipating energy due to deformation of the pavement structure)—results in wasted fuel because the dissipated energy does not contribute to the vehicle’s forward movement. Past studies on PVI and the three elements that impact PVI—texture, roughness, and deflection—have been empirical in approach, using actual trucks on actual pavements. This approach has ignored the pavement layer structure and material properties, and has led to high variability in the reported results.

UK study finds fifth of car fuel-efficiency savings eroded by increased driving; long-term rebound effect
February 10, 2016
Around a fifth of the energy-saving benefits of fuel-efficient cars are eroded because people end up driving them more, according to a study into British motoring habits over the last 40 years.
Using data from 1970 to 2011, energy experts at the University of Sussex found a long-term rebound effect among British car-drivers of around 20%. Published in an open access paper in the February issue of the journal Energy Economics, this is the first estimation of this rebound effect—a term used to describe the increased consumption of cheaper energy services—for car travel in Great Britain.
Study of eco-driving in hybrids finds need for systems that facilitate energy-efficient behaviors
January 30, 2016
A study of eco-driving behavior in hybrid electric vehicles (HEVs) by a team from Technische Universität Chemnitz (Germany) and the University of Southampton (UK) has found that simply providing drivers with a technology that has the potential for high energy savings—i.e., a hybrid—is not sufficient to result in high energy savings; systems must be developed in a way that facilitates energy efficient behaviors.
Put another way, they found that eco-driving motivation does not guarantee ecodriving success. Their study showed that even among drivers who were highly motivated for eco-driving, the individual differences in applied ecodriving strategies were still substantial. Building on the results, the team presented a number of suggestions for the design of systems that facilitate ecodriving. A paper on their study is published in the journal Applied Ergonomics.
Federal-Mogul Powertrain cuts engine valve development time using new simulation model
January 28, 2016

Woodruff School of Mechanical Engineering at Georgia Tech.
Northwestern researchers discover crumpled graphene balls are a promising lubricant additive
Researchers at Northwestern University’s McCormick School of Engineering have found that crumpled graphene balls are an extremely promising lubricant additive. In a series of tests, a polyalphaolefin base oil with only 0.01–0.1 wt % of crumpled graphene balls outperformed a fully formulated commercial lubricant in terms of friction and wear reduction. A paper on their work is published in the Proceedings of the National Academy of Sciences.
For the average car, 15% of the fuel consumption is spent overcoming friction in the engine and transmission. While oil helps reduce this friction, researchers have long sought additives that enhance oil’s performance. Ultrafine particles are often used as lubricant additives because they are capable of reducing friction and protecting surfaces from wear. They also tend to be more stable than molecular additives under high thermal and mechanical stresses during rubbing. However, they also can aggregate, reducing the effective concentration.
ExxonMobil projects 25% energy demand increase between 2014-2040, 50% decline in carbon intensity; hybrids to be 40% of new car sales
January 25, 2016
Global energy demand will increase 25% between 2014 and 2040, driven by population growth and economic expansion, ExxonMobil forecasts in the 2016 edition of its annual The Outlook for Energy. At the same time, energy efficiency gains and increased use of renewable energy sources and lower carbon fuels, such as natural gas, are expected to help reduce by half the carbon intensity of the global economy.
During the period, the world’s population will increase by about 2 billion people and emerging economies will continue to expand significantly, according to the forecast. Most growth in energy demand will occur in developing nations that are not part of the Organization for Economic Co-operation and Development (OECD). Per capita income in those countries is likely to increase by 135%.
Bosch says its haptic gas pedal can reduce fuel consumption up to 7%; safety warnings via nav and V2X systems
The automotive industry has been exploring the use of haptic gas pedal technologies as a way to reduce fuel consumption and increase safety by signaling the driver using a mechanism such as a vibration or a counterforce in the accelerator pedal. Continental announced its Accelerator Force Feedback Pedal in 2010, Frost & Sullivan anticipates wide premium-segment deployment of the active gas pedal technology post-2018 (earlier post); and Mercedes-Benz offers the technology in the C 350 PLUG-IN HYBRID (earlier post).
Bosch now says that its active gas pedal allows drivers to reduce fuel consumption by as much as 7%. This is possible because the gas pedal can be networked with other automotive functions, such as the transmission. Up to now, the only indication drivers have had of the best time to shift gear has been in the form of small arrows on the instrument display. The active gas pedal comes with the option of a palpable indication of the best time to shift gear.
Driving Chevrolet’s 2015 Impala Bi-Fuel sedan
January 19, 2016
Chevrolet offers the 2015 Impala full-size sedan as an all-new bi-fuel model—the only manufacturer-produced full-size sedan in North America that can run on both compressed natural gas (CNG) and gasoline. Available at the end of 2015 to both fleet and retail customers in either LS or LT trims, the bi-fuel Impala features a dedicated version of the standard 3.6L V–6, with specific valves and hardened valve seats for improved wear resistance and durability with the CNG fuel system. The engine, mated to a six-speed automatic, is rated at an estimated 260 hp (195 kW) on gasoline and 230 horsepower (172 kW) on CNG.
EPA figures put combined fuel economy in gasoline mode at 20 mpg combined (17 mpg city/25 mpg highway), and 19 mpg combined (16 mpg city/24 mpg highway) with natural gas. That works out to 437 grams CO2 per mile with gasoline, and 343 g CO2/mile with natural gas.
ORNL team reviews fuel-injection strategies for low-temperature gasoline compression ignition
January 18, 2016
The potential for using low temperature combustion (LTC) in compression ignition engines (i.e., diesel) to reduce NOx and PM while maintaining high efficiency has attracted a great deal of research interest over the past several years. While achieving LTC with diesel fuel over a wide operating range has been shown to be difficult for several reasons, gasoline, with its high volatility and low chemical reactivity, offers a more attractive fuel option for LTC.
Accordingly, in the industry’s quest for lower fuel consumption and emissions, a number of schemes for achieving LTC gasoline compression ignition have emerged. Now, a team of researchers from Oak Ridge National Laboratory’s National Transportation Research Center (NTRC) has published a comprehensive, open-access review of a variety of fuel injection strategies being investigated for LTCGCI. The paper is available for download from the International Journal of Engine Research.
ICCT analysis shows growing divergence between official and real-world fuel economy values for new cars in Europe

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.

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.

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.
Freudenberg-NOK wins first regular-production order for dry gas-lubricated frictionless engine seals
October 05, 2015
Freudenberg-NOK Sealing Technologies (Freudenberg-NOK) has won its first major order for its new generation of dry gas-lubricated automotive seals—a first in the automotive market. The frictionless Levitex seals, a subject of the company’s research for years, will go into an engine for a global platform in 2017. The new seals function with a cushion of air, reducing both fuel consumption and CO2 emissions. CO2 reductions can be as high as 1 gram per kilometer driven.
Freudenberg-NOK initially will produce Levitex seals in Europe, although the company plans to expand product into North America in the future as customer demand grows.
GM planning to “own” the customer relationship beyond the vehicle; autonomous Volts, car sharing and fuel cells
October 01, 2015
General Motors CEO Mary Barra and her leadership team outlined the company’s plans to capitalize on the future of personal mobility by owning the customer relationship beyond the vehicle, building upon nearly two decades of connectivity leadership.
GM also said it plans to strengthen its core business through global growth initiatives and an aggressive product launch cadence, while continuing to focus on driving cost efficiencies. As a result, the company expects to increase its earnings per share and generate significant shareholder value. The company shared its plans with investors during a conference at its Milford Proving Ground.
JAC and Ricardo develop production version of HyBoost concept; seeking 30% boost in fuel economy with same performance
September 30, 2015
Anhui Jianghuai Automobile Group Co Ltd (JAC) and Ricardo are collaborating on a project to develop the Ricardo HyBoost concept (earlier post)—a combination of low-cost technologies to deliver improved performance and fuel economy which featured recently in the Ricardo Centenary celebrations —into volume production on a JAC vehicle.
The Ricardo HyBoost concept is based on a downsized, highly boosted turbocharged direct injection gasoline (TDGI) engine giving improved fuel economy at low cost, linked to a 48V electrical architecture including a belt starter generator (BSG), DC-DC converter and a lithium-ion battery for energy storage.
Eaton launches new, more efficient TVS2 supercharger; targeting super-turbo systems
September 25, 2015

The announcement came at the 20th Supercharging Conference in Dresden, Germany.
Eaton’s Twin Vortices Series (TVS) is a Roots-type supercharger with four- lobe rotors and high-flow inlet and outlet ports. TVS2 technology builds on Eaton’s supercharger portfolio by delivering significant improvements in efficiency and increased capability, achieved through a rotor design that improves the internal aerodynamics. Key elements of this new design include:
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.

NRC Canada team investigates effect of gasoline particulate filter on PM from light-duty GDI engine
September 17, 2015
A team led by researchers from the National Research Council Canada has investigated the effect of the use of a gasoline particulate filter on the size and morphology of PM emitted from a light-duty gasoline-direct-injection (GDI) vehicle over the FTP-75 and US06 transient drive cycles.
Using transmission-electron-microscope (TEM) image analysis, they compared PM from a 2012 Ford Focus powered by a 2.0-liter wall-guided GDI engine, operating under globally stoichiometric condition, to the results for the same vehicle equipped with a catalyzed gasoline particulate filter (GPF). A paper describing their results is published in the ACS journal Environmental Science & Technology.
