Mercedes C55 AMG saloon

The front of the car had to be extended by 8cm, so while some designers were busy fitting 18-inch alloys, side skirts and a rear spoiler, others were ensuring the longer nose didn't spoil the imposing lines.

And after driving the C55 AMG, we can confirm that it goes as well as it looks. Mercedes claims a 0-60mph time of 5.2 seconds and a 155mph top speed - and we can believe it! Thanks to the 510Nm of torque, overtaking is in the warp speed category, whether you use the steering wheel button shift or full auto mode, while the quad tail-pipes burble menacingly. The trouble is, even a slight tap on the accelerator causes the car to surge forward. The all-or-nothing throttle means the warning light for the revised ESP seems to be on more than off as the rear tyres struggle for grip. In the dry this can be fun - but wet, twisty roads are not for the faint-hearted.

If you want to cover distances fast and in comfort, the C55 AMG makes for a good companion. But B-road drivers would be better off in a less potent car.
