Two Turbos, 580 Horses
For all the RS6's visual drama, though, it's what lurks underneath the hood that is sure to set tongues wagging at this Audi's debut in Frankfurt. The previous model's Cosworth-tweaked twin-turbocharged 4.2-liter V8 is history; this new RS is powered by a twin-turbocharged version of Audi's 5.2-liter V10 engine featuring the latest direct-injection system.

Peak power is put at 580 hp at 6,250 rpm with a mountainous 479 pound-feet of torque at just 1,500 rpm. These numbers eclipse the naturally aspirated 5.0-liter V10 of the BMW M5 by 80 hp and 96 lb-ft, while they surpass the 6.2-liter V8 of the Mercedes-Benz E63 AMG by 73 hp and 10 lb-ft.
