Downsized 5.5L V8 Biturbo in S 63 AMG Delivers 25% Fuel Savings Compared to Predecessor; Stop-Start is Standard

Green Car Congress

In addition to its twin turbos, the new eight-cylinder unit—known internally as the M 157—features gasoline direct injection with spray-guided combustion and twin turbochargers. The wet start-up clutch replaces a conventional torque converter, and helps to save fuel. AMG has developed a 5.5-liter The new AMG 5.5-liter

Researchers propose evaluating alt fuel efficiency based on energy rather than volume; impact of ethanol on vehicle efficiency and GHGs

Green Car Congress

Relative changes in vehicle energy efficiency (VEE) (km/MJ) on ethanol/gasoline blends over those on gasoline for different blending levels. Several recent highly cited LCAs that have incorporated vehicle efficiency differences between gasoline and ethanol/gasoline blends could potentially be misleading. Click to enlarge.
