Our spy photographers caught Audi’s RS6 super sedan barely disguised. Expect a V10 engine with 580hp, when it debuts later this year.

The horsepower wars in Europe show no signs of slowing down, as witnessed by Audi’s latest RS 6 sedan. Undergoing cold weather testing in Scandinavia, our spy shots give us the best view yet of what to expect when the production model debuts later this year.

Powered by the same V-10 as found in the RS 6 Avant ,which debuted at the Frankfurt Auto Show, the engine is expected to put out 580hp and 650Nm of torque. Expect a 0-100km in less than 4.6 seconds and 0-200km/h by the 15 second mark.
