Mercedes Benz-AMG C63

The Mercedes-AMG C63 is a high performance saloon car that’s been designed to rival models such as the BMW M3 and Audi RS4.Based on the Mercedes C-Class compact executive saloon, the C63 features a subtly reworked version of the twin-turbo 4.0-litre V8 engine that recently made its debut in the Mercedes AMG GT sportscar. Despite being smaller than the old C63’s naturally 6.2-litre engine, the new unit manages to deliver even more power and even greater efficiency.

Like the larger E63, the new C63 is now available in standard and even more powerful C63 S guises. The entry-level model delivers 469bhp, 650Nm of torque and a 0-62mph time of 4.1 seconds, while the S packs a hefty 503bhp and 700Nm, but only lowers the time for the benchmark sprint by a tenth of a second. Both engines achieve 34.5mpg on the combined cycle and emit 192g/km of CO2.

Performance for both versions is blistering. The V8 engine responds crisply to the throttle, while the muscular torque delivery allows you to blast past slower traffic in the blink of an eye. Adding to the drama is the seven-speed auto gearbox that delivers fast and crisp shifts, while the optional £1,000 sports exhaust provides a spine-tingling soundtrack.

 Even better, the inclusion of uprated suspension and heavily revised steering has helped transform the standard C-Class’ handling. There’s loads of grip, rock solid composure and the ability to subtly adjust the car’s line using a combination of steering and throttle.

Visually there’s little to differentiate the C63 and C63 S models, but both get a number of tweaks that help them stand out from standard C-Class variants. The most obvious changes are the deeper front bumper, side skits, subtly vented front wings and quad exhaust layout. Eagle-eyed fans will also notice that the C63 rides on 18-inch alloys, while the S features larger 19-inch rims. As before, the fast Mercedes flagship is available in both four-door saloon and practical estate bodystyles.

As with the exterior, Mercedes has taken a low-key approach with the C63’s cabin. There’s a bespoke AMG instrument cluster, a chunky three-spoke steering wheel and heavily bolstered sports seats, but the rest of the interior is pure C-Class. That’s no bad thing, because the slick design and top notch finish help create a real sense of occasion.

You get a decent haul of standard kit, too, including sat-nav, leather seat trim and LED headlamps. However, as with any Mercedes model it’s easy to get carried away on the extensive and expensive list of options, such as the £2,595 Premium Pack that adds keyless go, a Burmester sound system and a panoramic sunroof.
