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. They range from the start-stop system to a wide variety of measures aimed at reducing friction. The demand-controlled oil pump varies oil pressure in two stages.
