ExxonMobil: global GDP up ~140% by 2040, but energy demand ~35% due to efficiency; LDV energy demand to rise only slightly despite doubling parc
December 10, 2014
|As the world population increases by the estimated 30% from 2010 to 2040, ExxonMobil sees global GDP rising by about 140%, but energy demand by only about 35% due to greater efficiency. Click to enlarge.|
Significant growth in the global middle class, expansion of emerging economies and an additional 2 billion people in the world will contribute to a 35% increase in energy demand by 2040, according to ExxonMobil’s latest Outlook for Energy report.
Even as demand increases, the world will continue to become more efficient in its energy use, according to the 2015 Outlook for Energy: A View to 2040. Without efficiency gains across economies worldwide, energy demand from 2010 to 2040 would be headed toward a 140% increase instead of the 35% forecast in the report.

The company has customers located in the US, Japan, Europe, China and India and its current engine programs range from 45 hp to more than 5,000 hp.
ICCT study compares leading global driving cycles and provides usable conversion factors for CO2 emissions
December 08, 2014
A team at the International Council on Clean Transportation (ICCT) has compared the dynamics of the four leading driving cycles worldwide—the US CAFE standards (a composite of FTP75 and HWFET); the New European Driving Cycle (NEDC); Japan’s JC08; and the recently developed Worldwide Harmonized Light-Duty Test Cycle (WLTC)—and their impacts on fuel consumption and CO2 emissions on an equal basis. (WLTC will be replacing NEDC in a few years.)
The result is a set of usable conversion factors for distance-based CO2 emissions among the different driving cycles. The ICCT team determined these factors on distinct levels of detail, characterized by technology parameters such as share of diesel engines in the fleet, vehicle size, share of hybrid systems, aerodynamic drag, and others. This study updates and refines an earlier analysis completed in 2007. (Earlier post.) The new study uses a different methodology with different mathematical approaches.

|Audi A1. Click to enlarge.|
Since their introduction on the market in 2010, the Audi A1 and A1 Sportback have sold more than 500,000 units worldwide. Audi is now refreshing its A1 models, including the offer of six engines—gasoline and diesel—that are new or that have been intensively further developed.
For the first time, Audi is offering completely new three-cylinder engines: the 1.0 TFSI gasoline engine and the 1.4 TDI diesel. The 1.4 TDI follows the 2.0L 4-cylinder engine as the second engine in the Volkswagen Group’s modular diesel engine platform (MDB). (Earlier post.) Power output—ranging from from 66 kW (90 hp) to 141 kW (192 hp)—has been increased in most engines, while fuel economy has been reduced by as much as 10% percent. The seven-speed S tronic is available for all engines, either optional or standard (with the 1.8 TFSI).
Volkswagen outlines a range of near-term technologies for reducing fuel consumption and emissions; stop-start 2.0, 10-speed DSG
November 11, 2014
Volkswagen presented its latest technologies for reducing fuel consumption and CO2 emissions—which includes the first 10-speed dual-clutch gearbox (DSG)—in an Innovation Workshop for the media at the Ehra-Lessien test track facility near Wolfsburg.
Volkswagen AG has set the goal of becoming the world’s most sustainable carmaker by the year 2018. Compared to baseline figures for 2010, the Group wants to reduce energy and water consumption, waste generation and emissions (including CO2 emissions) by 25% in all of its business areas. (I.e., VW’s “Strategy 2018”, earlier post.) To achieve this, the Volkswagen brand—the highest volume brand of the Group—is counting on electric mobility (zero-emission and plug-in hybrid models); on continually more fuel-efficient combustion engines and gearboxes; progressive lightweight design; aerodynamics; and efficiency “in every conceivable area”.
New Unipiston clutch piston technology in series production; enables better fuel economy
November 06, 2014
Federal-Mogul Powertrain’s new high-modulus injection-molded Unipiston clutch pistons are now in series production at the company’s facility in Chivasso, Italy. The technology was a 2013 Automotive News PACE Award Winner in the process category.
Unipiston is a one-piece, rubber-to-metal bonded piston that hydraulically engages clutches to activate the gearshift. The compact one-piece design reduces the number of leak paths while improving reliability and simplifying assembly, and allows transmission designers more flexibility, including increased clutch apply pressures, higher rotational clutch speeds, and larger diameter clutches. This flexibility enables transmissions with additional clutches to be packaged in a smaller space, while providing improved fuel economy, reduced emissions and enhanced vehicle performance.
Volkswagen begins production of latest-gen DSG at new plant in China; 1.2M unit capacity by 2016
November 05, 2014
Volkswagen started production of the latest generation of its advanced dual-clutch gearbox (DSG), the DQ380, at its new Tianjin components plant in North China. Initially, the new Volkswagen plant will have an annual production capacity of 450,000 units, which will be increased to 1.2 million units by 2016. Volkswagen has invested about €265 million (US$332 million) in the first stage of the plant.
The dual-clutch gearboxes produced especially for the Chinese market will be used in several Group models in China in the future. With the DQ380 gearbox in combination with the third generation of the new EA888 engine, which is produced at the engine plants in Changchun and Shanghai, Volkswagen will achieve a consumption reduction of 0.5 l/100 km and therefore a CO2 reduction of 12 g/km compared with the previous generation.

|Two-stroke diesel in test car. Click to enlarge.|
A European project led by Renault, in collaboration with the Czech Technical University in Prague, IFP Energies Nouvelles, Delphi, Le Moteur Moderne (LMM) and Universitat Politècnica de València have developed an advanced two-cylinder, two-stroke compression ignition (CI) engine integrating LTHC (low temperature homogeneous combustion) as part of the European project POWERFUL (POWERtrain for FUture Light-duty vehicles).
The €25-million (US$31-million) FP7 project, which ended in June, also supported two other engine projects: an advanced four-stroke two-cylinder SI engine concept characterized by low-cost / low emissions; and an advanced four-stroke, three-cylinder CI engine concept able to run also on new tailored fuels and integrating the LTC (low temperature combustion) mode in the CI combustion system.
Hyundai & Kia to pay record $100M penalty for GHG conformity violations & lose $200M+ in emission credits
November 03, 2014
Hyundai and Kia will pay a combined $100-million civil penalty, the largest in Clean Air Act history, to resolve violations concerning the testing and certification of vehicles sold in the US (“Conformity Violations”) and will spend approximately $50 million on measures to prevent any future violations. Hyundai and Kia will also forfeit 4.75 million greenhouse gas emission credits that the companies previously claimed, which are estimated to be worth more than $200 million. (The value for GHG emission credits is not set or controlled by EPA; it is determined by the market of automakers that buy and sell these credits.)
The US Environmental Protection Agency (EPA) and the US Department of Justice announced the historic settlement which will resolve alleged Clean Air Act violations based on the sale of close to 1.2 million vehicles that will emit approximately 4.75 million metric tons of greenhouse gases in excess of what the automakers certified to EPA.
ICCT analysis projects new 2020 European car CO2 target value of 100 g/km under WLTP
The anticipated transition from the New European Driving Cycle (NEDC) to the Worldwide Harmonized Light Vehicles Test Procedure (WLTP) for the European type approval procedure for fuel consumption and CO2 emissions of cars will result in a new WLTP-based target of 100g CO2/km for 2020, up from 95 g/km, according to a detailed analysis by a team at the the International Council on Clean Transportation (ICCT). If the ambient test temperature is also changed for the EU-WLTP (to 14 °C instead of 23 °C), an additional correction of 2 g CO2/km would be appropriate, making the target 102 g CO2/km, the authors said.
The currently in-use NEDC includes a number of tolerances and flexibilities and no longer accurately reflects current advanced technologies; the gap between official and real-world fuel-economy figures in Europe has risen to about 38%, according to an earlier report published by the ICCT. (Earlier post.) The European Union is planning to replace the NEDC with the newly developed Worldwide Harmonized Light Vehicles Test Procedure in 2017.
First look at all-new Voltec propulsion system for 2G Volt; “the only thing in common is a shipping cap”
October 29, 2014
The second-generation Volt, which makes its world debut in about 10 weeks at the North American International Auto Show in Detroit, features a clean-sheet, all-new Voltec propulsion system—new battery, new electric drive unit, new power electronics and new range-extending engine. At an introductory media briefing on the new powertrain held at the Warren Transmission Plant in Michigan, where the new drive unit will be built, Larry Nitz, GM Executive Director, Transmission and Electrification, noted that the only common part between the gen 1 and gen 2 drive units was a little yellow plastic intra-plant shipping cap for the manual selector.
The battery cells, with a tweaked NMC/LMO chemistry from LG, increase storage capacity by 20% volumetrically when compared to the original cell. The drive unit features a large number of changes: new roles for the two motors, two clutches instead of three, and a smaller power electronics unit integrated into the housing among them. (No more big orange high-voltage cables underneath the hood.) The new direct-injected 1.5 liter engine with cooled EGR features a high compression ratio and is optimized to function in its range extender role.

The electric motor in Visio.M draws its power from a lithium-ion battery pack behind the seats, which consists of consumer cells and provides a capacity of 13.5 kWh.
EPA Trends on EVs and PHEVs; beginning of a “measurable and meaningful impact” on new vehicle fuel economy and emissions
October 11, 2014
The US Environmental Protection Agency’s (EPA) annual report “Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends” (earlier post) has, in its past editions since its inception in 1975, treated alternative fuel vehicles—electric vehicles (EVs), plug-in hybrid vehicles (PHEVs), and compressed natural gas (CNG) vehicles—separately from gasoline and diesel vehicles, with the vast majority of its analysis limited to gasoline and diesel vehicles only.
The agency’s reasoning was that since alternative fuel vehicle production has generally been less than 0.1% of total vehicle production until very recently, the impact of excluding alternative fuel vehicles was negligible. With alternative fuel vehicles now approaching 1% of new vehicle production, however, they are in fact beginning to have a “measurable and meaningful impact” on overall new vehicle fuel economy and CO2 emissions.
EPA annual trends report finds new vehicle fuel economy at record 24.1 mpg; new powertrain technologies rapidly gaining share
October 10, 2014
EPA released the latest edition of its annual report on trends in CO2 emissions, fuel economy and powertrain technology for new personal vehicles in the US. Among the top-level findings was that Model year 2013 vehicles achieved an average of 24.1 mpg (9.76 l/100 km)—a 0.5 mpg increase over the previous year and an increase of nearly 5 mpg since 2004. Fuel economy has now increased in eight of the last nine years; average carbon dioxide emissions are also at a record low of 369 g/mile in model year 2013. The majority of the carbon and oil savings from current vehicles is due to new gasoline vehicle technologies, the report observed.
The report, “Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends: 1975 Through 2014”, also found that the light truck market share increased slightly in MY 2013, after several years of volatility; that the vehicle weight trend is flat and vehicle power trend is increasing more slowly; that many new powertrain technologies are rapidly gaining market share; and that consumers have an increasing number of high fuel economy/low CO2 vehicle choices.

New “2-in-1” EV unit integrates traction motor and A/C compressor for increased range in hot climates
October 01, 2014
Engineers from Nanyang Technological University (NTU) and the German Aerospace Centre (DLR) have designed a “2-in-1” electric motor unit which can increase the range of electric vehicles in hot climates. This innovative electric machine integrates the A/C compressor, the compressor drive motor and the traction motor into a single housing physically clutching with the compressor during braking events.
The approach unifies the EV traction and compressor drives into a single housing which drive together during braking events. Based on simulations and analysis, the team expects the system to reduce battery consumption by at least 3% compared to existing mechanisms while improving the regenerative energy capturing capacity of the system by 8%. Overall, the novel design could increase the range of electric vehicles by an additional 15 to 20% with other modifications, the researchers suggested.
Honeywell Global Turbo Forecast projects 49M turbocharged vehicle sales, $12B revenue per year by 2019
September 30, 2014
The automotive turbocharging industry will generate $12 billion in revenue by equipping 49 million vehicles with turbochargers annually by 2019, according to Honeywell Turbo Technologies’ 2014 Global Turbo Forecast. The continued growth of turbocharging technologies will be driven by requirements for manufacturers to meet global environmental emissions regulations and bolstered by strong demand in emerging markets.
Automakers are turning to downsized turbocharged engines to satisfy more stringent global fuel economy and emission regulations and customer demand for better-performing vehicles. Turbochargers can help downsized engines improve fuel economy as much as 20 to 40% in gasoline and diesel engines, respectively, when compared with larger naturally aspirated engines and still provide the same or better engine performance. In addition to improving fuel efficiency, downsized turbocharged engines also reduce harmful exhaust emissions.

Promising results from Mercedes-Benz fleet test of Clariant high-octane cellulosic E20
September 23, 2014
Clariant, Haltermann and Mercedes-Benz have fleet-tested high-octane sunliquid 20 fuel—containing 20% cellulosic ethanol produced from straw—since January. (Earlier post.) The test found that the use of sunliquid 20 improves engine efficiency—more than compensating for its 4% lower energy content compared to E10. For drivers, this means with sunliquid 20, CO2emissions are reduced while consumption remains the same.
Use of sunliquid 20 also resulted in a 50% improvement in particle emissions count in contrast to the EU 5 reference fuel. The cellulosic ethanol in sunliquid 20 demonstrates greenhouse gas emission savings of up to 95% across the entire value chain (well-to-wheel perspective) without competing with food production or agricultural acreage.

Study finds US refining sector could produce higher octane E20 and E30 at modest additional cost; enabling more efficient engines
September 18, 2014
|A new study concludes that using ethanol can be a cost-effective approach to increasing the octane rating of the US gasoline pool. Source: ACS, Hirshfeld et al. Click to enlarge.|
A number of studies recently have pointed out that increasing the octane rating of the US gasoline pool (currently ∼93 Research Octane Number (RON)) would enable higher engine efficiency for light-duty vehicles through reducing engine knock constraints, thereby enabling the design of new spark-ignition engines with higher compression ratios and boost levels. (Earlier post.) Such a move would also have significant implications for refineries in the US refining sector, whether the higher octane was achieved via more severe refining operations, increased use of ethanol, or both.
A linear programming analysis of US refining sector by a team from MathPro Inc., Ford, GM and Chrysler has found that, by increasing the volume of ethanol, the refining sector could produce hydrocarbon blendstocks for oxygenate blending (BOBs) yielding finished E20 and E30 gasolines with higher octane ratings at modest additional refining cost (ARC): e.g., ∼1¢/gal for 95-RON E20 or 97-RON E30; 3–5¢/gal for 95-RON E10, 98-RON E20, or 100-RON E30; and 96-RON E10, 99-RON E20, or 101-RON E30 gasoline pools at approximately 10¢/gal.
MAHLE NanoNapier Steel piston ring helps reduce weight and improve quality
MAHLE has developed a piston ring with new technology that offers engine manufacturers improvements in weight, quality and overall value. MAHLE’s new “second” piston ring uses chrome-silicon steel to replace cast iron traditionally used for the second of three rings found on gasoline-powered spark-ignition engines. MAHLE’s thinner, lighter-weight steel-wire design for the second ring is based on the company’s own NanoNapier Steel (NNS) technology for which a patent is pending.
Conventionally, there are two types of piston rings: compression and oil control. A piston assembly includes one or more compression rings that generate a seal between the outer surface of the piston and the wall of the cylinder to prevent high-pressure combustion gases and air from escaping the combustion chamber. Today’s engines have three piston rings: two compression rings: top (or first) and second and the oil control ring. The second ring is known as a Napier ring.

|EOLAB. Click to enlarge.|
Renault has presented EOLAB, a new prototype which explores ways to deliver ultra-low fuel consumption. EOLAB delivers NEDC combined cycle fuel consumption of 1 liter/100 km (235 mpg US), equivalent to 22g of CO2/km. To achieve such low figures, the designers focused their efforts on three main areas: minimizing weight; leveraging aerodynamics with active systems; and using the “Z.E. Hybrid” plug-in hybrid system—the last offering all-electric trips of up to 60 km (37 miles) at speeds of up to 120 km/h (75 mph).
Conceived around a B-segment platform, the prototype incorporates around 100 new, realistic technological developments that are designed to be introduced gradually on upcoming Renault vehicles. EOLAB features materials such as magnesium and aluminium, which are extremely light and also much cheaper than titanium. Meanwhile, the notion of such a car being produced in large numbers within the next 10 years was dialed into the plan from the start.

Chevy’s Cruze Diesel: a compact diesel contender in the US
September 08, 2014
|The Cruze Diesel is identified by a discreet badge on the trunk. Click to enlarge.|
US buyers hunting for a non-premium diesel passenger car (i.e., not a truck or SUV, and not a vehicle from BMW, Audi, Porsche or Mercedes-Benz) have until recently only had Volkswagen-brand cars as an option: Beetle, Golf, Jetta, Passat. Accordingly, Volkswagen of America (VoA) diesel sales to date in 2014 represent slightly north of 23% of all Volkswagen of America sales. In August, Jetta posted 3,988 diesels sales (26% of Jetta sales, while Passat TDI sales were 2,767 units, representing 30.1% of sales of the vehicle.
However, Chevrolet is trying to challenge that passenger car diesel hegemony with the compact Cruze Diesel, introduced for MY 2014, and now with a facelift for MY 2015. (Earlier post.) Chevrolet is positioning the Cruze, which features a US-modified 2.0L diesel from GM’s European lineup (the engine is manufactured in Kaiserslautern, Germany) to challenge Jetta on the basis of highway fuel economy and power, as well as content. Based on a week with the car (MY2014), the claimed fuel economy superiority may be tough to realize in real-world driving (especially in the face of the new, more fuel-efficient diesel in the 2015 Jetta, earlier post) but overall, the Cruze Diesel is a worthy challenger, and a very good and thrifty drive, especially on the highway.

GMZ-led project tracking to deliver vehicular thermoelectric generators for Bradley Fighting Vehicle, Honda Accord
|The assembled 200W TEG tested in June delivered 270W of output. Click to enlarge.|
GMZ Energy and its partners are on track to deliver a 1 kW thermoelectric generator (TEG) for the Bradley Fighting Vehicle as well as to design and to integrate a light-duty vehicle TEG into a Honda Accord as part of a DOE-funded project. Thermoelectric materials convert temperature differences into electric voltage; a TEG in a vehicle is designed to convert waste heat to power. GMZ Energy, a provider of advanced nano-structured thermoelectric generation technology, was co-founded by MIT’s Professor Gang Chen and collaborator Zhifeng Ren of the University of Houston.
The project is using Half-Heusler (HH) thermoelectric materials (earlier post) in designing the vehicular TEG systems. Although these materials (ferromagnetic intermetallic alloys with a strong crystal structure that allows great stability at high temperatures) have a ZT (dimensionless figure of merit) lower than some other TE materials such as Skutterudites, the mechanical strength and the reliability of HH compensates for this deficit, according to GMZ.

August 04, 2014
|VTTI test display for adaptive road signs. Click to enlarge.|
Researchers at the Virginia Tech Transportation Institute (VTTI) are in the early stages of investigating the development of adaptive stop and yield traffic signs. The concept is to replace conventional roadside stop and yield signs with an in-vehicle display that would automatically alert the driver of what actions to take, if any. If no other car is present at the intersection, the driver would be allowed to pass through and go on—i.e., without halting before proceeding.
Alexandria Noble is spearheading the proof of concept adaptive stop-yield study with funding from the US Department of Transportation and under direction of her adviser and project manager, Thomas A. Dingus, the institute’s director and an endowed professor of civil and environmental engineering at Virginia Tech. Noble is the first student in the newly launched Human Factors Transportation Safety Graduate Certificate Program, led by the transportation institute.

Argonne VERIFI researchers applying GSA to investigate combustion engine parameters; seeking cleaner and more efficient engines
July 18, 2014
Researchers at Argonne National Laboratory, as part of the new Virtual Engine Research Institute and Fuels Initiative (VERIFI) (earlier post), are using global sensitivity analysis (GSA)—a specific form of uncertainty analysis which breaks down the uncertainty into constitute parts—to investigate a number of parameters in the internal combustion process. By gaining a better understanding of how these parameter uncertainties affect outcomes, the VERIFI researchers, along with colleagues at the University of Connecticut, are seeking to create cleaner and more efficient engines.
The parameters being investigated include the relationships between the diameter of the nozzle in the fuel injector; the dynamics of the fuel spray; the proportion of fuel to air in the combustion chamber; and the exhaust products. In an SAE paper presented at the World Congress this year, the researchers described the results of the first demonstration of GSA for engine simulations.
First high-heat plastic air intake manifold with integrated charge air cooler in production on hybrid sports car
|Plastic air intake manifold with integrated CAC for 3-cylinder 1.5-liter engine.|
The world’s first high-heat plastic air intake manifold (AIM) with integrated charge air cooler (CAC) in Stanyl Diablo, Royal DSM’s high-temperature-resistant polyamide 46, recently went into production on a recently introduced hybrid sports car—by its description (although not by confirmation from DSM) the BMW i8 (earlier post). Royal DSM noted that the use marks another major step forward in the use of thermoplastics in automotive high-heat zones.
The injection-molded AIM/CAC manifold operates at 220 °C and withstands pulses of high internal pressure. DSM worked closely together with a leading system supplier to develop the AIM/CAC combination, with DSM providing extensive development and processing support. The part is made in Stanyl Diablo OCD2100, which contains 40% glass fiber reinforcement as well as a specially developed and patented heat stabilizer. This grade has a continuous-use temperature of 220 °C and is able to withstand peak temperatures up to 250 °C.
OpEneR: improving EV range by optimizing energy management
July 17, 2014
|OpEneR partners have developed driving strategies and driver assistance systems to improve the efficiency and safety of electric vehicles. Click to enlarge.|
At its final review, the European research project OpEneR (“optimal energy consumption and recovery based on a system network”) presented collaboratively developed driving strategies and driver assistance systems to improve significantly the efficiency (and hence range) and safety of electric vehicles by optimizing energy management. (Earlier post.)
In comparison to a typical sporty driver, the OpEneR operation strategies resulted in a reduced energy consumption of 27 to 36%, with the trade-off of an increase in travel time of between 8 to 21%—depending on the driver’s willingness to follow the recommendations. Approximately 5 percentage points of the energy consumption reduction were due to intelligent torque distribution between front and rear electric motors in the demonstrators, which had no influence on travel time at all.

|Streamlines showing intake process for an SI engine in a FORTE simulation. Source: ANSYS. Click to enlarge.|
The US Environmental Protection Agency (EPA) has selected ANSYS simulation solutions to model in-cylinder combustion to develop an advanced test engine that will demonstrate fuel-saving and emissions-reducing technologies. The EPA’s test engine will help establish the feasibility of meeting recently issued fuel standards through improvements to combustion chamber geometries, fuel injection strategies, fuel composition, valve timing and intake conditions.
While physical prototyping and direct tests on real engine hardware can guide engine design, they are very costly and time-intensive. By using ANSYS FORTÉ, the EPA can experiment with engine design in a virtual setting. As a result, its engineers can quickly and inexpensively make multiple design iterations. ANSYS acquired FORTÉ as part of its acquisition of Reaction Design earlier this year. (Earlier post.)

The estimated 32 mpg (7.4 l/100 km) combined rating is segment-leading for a non-hybrid mid-size sedan and more than a 10% improvement over a 2015 Sonata SE powered by the 2.4-liter Theta II engine.
Toyota implements Atkinson cycle in non-hybrid ESTEC engine; up to 38% thermal efficiency and improved fuel economy
|Performance of the new ESTEC engine (1NR-FKE) compared to the current 1NR-FE engine applied in the Yaris. Yamada et al. Click to enlarge.|
Engineers at Toyota have developed an approach to applying the Atkinson cycle—used in the engines in Toyota hybrids since 1997—for engines in conventional, non-hybrid vehicles. The Atkinson cycle with a high compression ratio is a common approach that hybrid vehicle engines use to enhance thermal efficiency. However, the drawback of the high compression ratio is a reduction of engine torque; in a hybrid, the motor torque compensates for this reduction in engine torque. Thermal efficiency at low load areas is relatively more important with conventional engines than with hybrid engines and how to overcome these issues is significantly important with conventional engines, the Toyota developers observed.
The result of their work, presented in papers this spring at the SAE 2014 World Congress, the Vienna Motor Symposium, and the JSAE Annual Congress, is the new 1.3-liter ESTEC (Economy with Superior Thermal Efficient Combustion) in-line 4-cylinder Gasoline Engine (1NR-FKE). The ESTEC 1NR-FKE achieves 73 kW of output (3 kW higher than the 1NR-FE used in Toyota A and B segment vehicles such as Yaris, iQ, etc.) with thermal efficiency of up to 38%—equivalent to the engines in hybrids. Further, at low loads, the ESTEC engine improves fuel consumption by 11% in the JC08 mode.

Ford lowers fuel economy ratings for hybrids, plug-in hybrids, and Fiestas; goodwill payments to buyers coming
Ford Motor Company is lowering the fuel economy ratings for its 2013- and 2014-model year hybrid and plug-in hybrid vehicles, as well as most 2014-model year Fiestas. In some cases, the reduction was minor, on the order of 2-3%. The MKZ hybrid, however, was hit with a 15.6% reduction in combined fuel economy (45 mpg down to 38 mpg), and the C-MAX and Fusion plug-in hybrids saw about a 12% decrease in charge sustaining and charge depleting fuel economy, and about a 10% decrease in all-electric range.
Ford said it had identified an error with fuel economy ratings on the vehicles and notified the US Environmental Protection Agency (EPA). Ford worked with EPA as the agency retested the vehicles to determine the correct fuel economy ratings. Ford reviewed its entire line up to determine the vehicles that required further testing and revised the fuel economy ratings for the affected vehicles. No other label adjustments are planned.
