The Audi RS6 Avant is powered by a 4.0-liter V8 engine generating 560 horsepower between 5,700 and 6,700 rpm, and 516 pound-feet of torque (700Nm) between 1,750 and 5,500 rpm. This engine is equipped with two large twin-scroll turbochargers and an additional intercooler inside the cylinder-bank valley. With the new engine the RS6 Avant will sprint from 0 to 62 mph in just 3.9 seconds and up to an electronically limited top speed of 155 mph. However, when the car is equipped with the optional Dynamic Plus package, it can go up to a sphincter-clinching 189 mph.
