those which do not favor one technology over another through consumer incentives, federal subsidies, testing standards or technology-specific credits. The quickest and most cost-effective way to achieve our energy usage goals is through faster adoption of fuel-efficient downsized gasoline and diesel engines.
Continuing to emphasize a downsizing approach, Volkswagen presented two new engines at the at the 30 th Vienna Engine Symposium (7-8 May): the 1.2-liter Downsizing is rigorously being developed in the volume segments with the 1.2 L/100km (43 mpg US), with 129 g/km CO 2. It meets the EU 5 exhaust emission standard.

Other highlights include an all-aluminum crankcase, four-valve technology with adjustable camshafts, an air/water intercooler, generator management and the standard stop-start function. The new AMG 5.5-liter
year-over-year increase in fuel efficiency and reduction in GHG emissions standards, which will result in projected overall industry averages of 40.4 mpg and 199 g/mile CO 2 in 2026. We believe the industry could exceed the relaxed US efficiency standards as it must meet tighter standards in Europe, China, Japan, Korea and India.
GM says that the choice to use a small-displacement turbocharged engine for a more powerful Verano model is consistent with Buick’s effort to downsize its powertrains without sacrificing performance. The standard 2013 Regal four-cylinder engine also is equipped with eAssist. Verano’s standard Ecotec 2.4L
49% of respondents thought that powertrains would see the greatest percentage of material changes as a result of proposed 2025 CAFE standards. The auto industry’s current materials portfolio will need to be augmented to meet new 2025 fuel economy standards, according to a WardsAuto and DuPont Automotive survey conducted in late July.

Downsizing is a key element of Audi’s efficiency strategy. mpg), with 127 grams of CO 2 per kilometer (204 g/mile). TDI clean diesel quattro complies with the emission limits of the EU’s Euro 6 standard, expected to become law in 2014. mpg) [provisional figures]—the best in this power-output category, according to Audi.
liters of diesel fuel per 100 kilometers (47 mpg US)—the saving achieved through the use of the steel piston is around 3%. This is particularly advantageous for further downsizing concepts. The new pistons contribute to the maintenance of the same engine output (190 kW/ 258 hp), but with fuel consumption of around 5.0

” The more weight we can take out of our vehicles though use of alternative materials, and other lightweighting strategies that we have, that enables us to further downsize the engine—which is the biggest lever you can pull in the vehicle. As one current example, the 2011 Ford Explorer (3.5-liter
Engine downsizing and downspeeding are two strategies that can be applied to gasoline and diesel engines to improve vehicle fuel economy. They performed fuel economy and 0-60 mpg acceleration simulations for three shift schedule optimization strategies for 81 transmission gear ratio configurations of the supercharged configuration.
mpg US mpg) in 2011—an improvement of 1.8% mpg US) global average by 2030 for new cars. Reaching this level is ambitious but achievable, the paper noted; the enacted fuel economy standards around the world require annual improvements of up to 4.7%. The trend is toward smaller displacements (downsizing).
Based on test work already carried out, Ricardo estimates that a fuel economy improvement of up to 30% is possible with no loss of power or performance, using a downsized EBDI engine in place of currently available gasoline powertrain technology. liter EBDI engine—resulting in up to a 16.8% fuel economy improvement.
