Volvo to concentrate on hybrids and downsized engines for US

Green Car Congress

Volvo Car Corporation will rely on a powertrain strategy based on its new downsized 4-cylinder VEA (Volvo Environmental Architecture) engine platform ( earlier post ) and hybrids for the US market, said John Maloney, recently appointed President of Volvo Cars, US, in an interview at the Detroit Auto Show.

Mazdas new SKYACTIV gasoline and diesel engines are steps on the road to its Ideal Engine; focus on compression ratio

Green Car Congress

However, while Mazda plans to offer hybrid vehicles in the medium-term, its engineers are pushing hard to increase the efficiencies of both the gasoline and diesel platforms, moving toward what they call “the ideal Internal Combustion Engine.” Extreme compression ratio rather than downsizing. Although downsizing—i.e.,

Audi introducing 5-door A1 Sportback; fuel consumption as low as 62 mpg US for diesel versions

Green Car Congress

The new Audi A1 Sportback, which will go on-sale in 2012, is a five-door version of the compact 3-door A1. Buyers in Europe will be able to choose between three TFSI gasoline and three TDI diesel four-cylinder direct-injection engines producing between 63 kW (86 hp) and 136 kW (185 hp). The 105 kW (143 hp) 2.0

Federal-Mogul hybrid liner for cylinders reduces bore distortion and improves function in lighter, downsized engines; up to 40% reduction in oil consumption

Green Car Congress

Dynamic strength increases as well; in a cyclic pulsing pressure test, the Hybrid Liner showed no failure at pressures of up to 200 bar, whereas a standard liner block design cracked at 100 bar. The technology was a finalist in the 2012 Automotive News PACE Awards.

Bosch sees future requiring multiple powertrain technologies; the larger the vehicle, the more the electrification

Green Car Congress

Bosch does not believe there is just one powertrain solution for the future; most of the cars on the world’s roads are still running on diesel and gasoline, and things will stay that way for the rest of the decade, Bohr noted. Only the diesel engine will achieve this in the compact class, but the gasoline engine will come close.

Audi using supplementary port fuel injection to address particulates from gasoline direct injection

Green Car Congress

The EU has set a standard for 6 × 10 12 number/km limits between 2014 and 2017, tightening to 6 × 10 11 number/km. GDI technology provides fuel efficiency benefits from charge air cooling, more facile turbocharging, and the downsizing that these permit. Earlier post.). Earlier post.) Earlier post.).
