We compare three sports sedans – the Mercedes-AMG C63 S, the Audi RS5 Sportback and the Lexus GS F. Which is best? The super sedan segment is full of great cars, and we're all waiting to see the new BMW M3. But for now, should you buy an AMG C63? Only one can be crowned the winner. In this video, we take the V8 GS F, biturbo V8 C63 and twin-turbo V6 RS5 out onto the road.

Let us know your favourite fast sedan in the comments – and whether you think the GS, C-Class or RS5 is best!
