This does, perhaps, oversimplify the engineering a bit, but the original RS6 still wasn't quite as radical a departure from the rest of Audi's lineup as the second RS6 would be. This turbocharged and intercooled version of the engine produced 450 horsepower (fully 101 more than the contemporary competing Mercedes-Benz
E55 AMG), as well as 428lb-ft of torque. A wide power band came from the combined use of variable valve timing and turbocharging, and peak torque was available all the way from 1,950 to 5,600 RPM. This meant that, despite the car's considerable weight, it could sprint to 60mph in just 4.6 seconds.
