Mercedes-Benz C63 AMG coupe, an AW Flash Drive Car Review
What is it?

The powerful, rapid and loud range-topping version of Mercedes-Benz's new C-class coupe lineup, the C63 AMG coupe. It's a sister car to the recently face-lifted C63 AMG sedan, with which it shares elements of its styling, mechanical package and excellent interior. It takes over from the CLK55 AMG, providing renewed competition for the likes of the Audi RS5, the BMW M3 and the Lexus IS F.

Powering the latest in an ever-growing range of Mercedes-Benz performance models is its naturally aspirated 6.2-liter V8 engine. As in the C63 AMG sedan, it kicks out a nominal 451 hp at 6,800 rpm. However, an optional Performance package--which brings the same lightweight pistons, connecting rods and crankshaft as those used in the SLS--bumps its power up to 480 hp.

That is 37 hp more than the RS5's 4.2-liter V8 can manage, a substantial 66 hp beyond the M3's 4.0-liter V8 and an additional 63 hp over the IS F's 5.0-liter V8. The C63 AMG coupe trumps its rivals on torque, too, possessing 443 lb-ft at 5,000 rpm--370 lb-ft of which is available between 2,000 rpm and 6,250 rpm.

Just one gearbox choice is offered: AMG's seven-speed, multiclutch transmission. It is based on the standard C-class coupe's seven-speed 7G-tronic automatic unit but replaces the torque converter with an automatically operated clutch for more rapid shifting. As in other AMG models, it comes with remote shift paddles and offers four driving modes, including manual, which sees it hold on to gears at the redline rather than automatically select the next gear. There's also a race-start mode.

The C63 AMG coupe uses a different chassis setup than regular versions of the C-class coupe. The biggest change concerns the track measurements, which are up by 0.8 inch to 61.8 inches at the front, and down by 1.1 inches at the rear to 60.0 inches.

The setup of the three-link front and multilink rear suspension has also been modified in some detail, with greater negative camber, reduced ride height, unique spring and damper rates and larger-diameter antiroll bars--all aimed at bringing added response, extending grip levels and introducing improved body control. Underpinning it all are relatively narrow 235/40ZR-18 front and 255/35ZR-18 rear Continental Sport Contact tires.

What is it like to drive?

There's a lot like about the C63 AMG sedan in overall character. But given that they share their entire mechanical package, save for a few unique chassis tweaks, we really didn't expect anything else from the C63 AMG coupe. Still, one thing is clear: Even before you turn a wheel, the C63 AMG coupe makes the old CLK55 AMG that was built until 2009 appear just that--old.

Predictably, the driving experience is dominated by the engine. It might have been replaced by a newer twin-turbocharged 5.5-liter mill in other Mercedes-Benz performance models, but the big, naturally aspirated V8 is as memorable as ever, possessing a truly potent combination of response and firepower.

As impressive as the outright power is the ease at which you can tap into the vast reserves of torque. There's prodigious shove pretty much from idle onward. Reach the mid-range, and it is nothing short of explosive. The performance is effortless, enabling it to reach seriously high speeds without seemingly drawing a breath. On top of this, it makes a wonderful sound at full throttle, emitting a deep baritone growl that fully befits its muscle-car brief.
