Efficiency, Performance From Audi’s Electric Turbo Prototype
Based on the firm’s RS5 performance coupe, Audi’s turbocharged tech could legitimately wear bright 80s-style turbo stickers. And in fact, it does–in a sort of restrained, Germanic way.
But while normal RS5s motor down the road with a V-8 gasoline engine, the RS5 prototype uses Audi’s 3.0-liter TDI-badged V-6 turbodiesel, equipped with a brace of turbochargers.
The concept develops 553 lb-ft of torque from just 1,250 rpm–111 lb-ft more than Audi’s normal twin-turbo 3.0 TDI. Power has increased too, rising from 272 hp to a 385 hp maximum output.
Ett helt sjuk högt vridmoment.
