New Audi S models to feature new downsized 4.0L V8 with cylinder deactivation, energy recuperation and start-stop

Green Car Congress

This is a downsized platform from the prior 5.2L It accelerates the S6 from 0 to 100 km/h (62 mph) in 4.8 It accelerates the S6 from 0 to 100 km/h (62 mph) in 4.8 Both models have an electronically governed top speed of 250 km/h (155 mph). Acceleration from zero to 100 km/h (62 mph) takes 4.2 Compared to the 5.2L

Volkswagen Emphasizes Downsizing at 30th Vienna Engine Symposium; Highlights 1.2 TSI and 1.6 TDI

Green Car Congress

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 The potential of internal combustion engines is far from exhausted. Downsizing is rigorously being developed in the volume segments with the 1.2 Click to enlarge. TSI and the 1.6

Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

Internal combustion engines have been significantly improving in the past decade, after the adoption of technologies such as Gasoline Direct Injection, mild electrification, downsizing and turbocharging. The OSU EcoCAR prototype vehicle features an extended-range electric architecture with a downsized 1.8L —Marcello Canova.

Downsized 4.0 TFSI for Audi S8 cuts fuel consumption 23% compared to predecessor; cylinder deactivation and start-stop

Green Car Congress

Audi’s principle of downsizing: “ Forced induction replaces displacement ” One twin-scroll turbocharger per cylinder bank compresses the fresh air. From each pair of cylinders, the exhaust ports lead separately to a manifold and the turbocharger housing; they are not combined until immediately ahead of the turbine.

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

Green Car Congress

For the first time, AMG is also utilizing the advantages of gasoline direct injection with spray-guided combustion and piezo-electric injectors: thanks to its higher thermodynamic efficiency, this technology makes more efficient use of fuel and leads to lower exhaust emissions. The 100 km/h mark is reached in 4.4

CPT VTES Electric Supercharger Selected for Two Projects

Green Car Congress

When applied to a radically downsized 1.2-liter liter turbocharged engine, VTES delivers in excess of a 50% increase in torque at engine speeds below 3,000rpm, more than compensating for insufficient power from the exhaust turbine. More than 90% of the available torque is delivered in less than a second. Compared with a 1.6-liter
