The flagship Mercedes S-Class gets its tracksuit on in 576bhp S63 AMG Coupe guise and what a tracksuit it is
Verdict ****
The Mercedes S63 AMG Coupe is a seriously impressive piece of engineering. It’s blisteringly fast and handles better than it has any right to, but it’s also a near-perfect companion for a 200-mile motorway journey. In fact, thanks to the semi-autonomous mode, it’ll take most of the strain for you. The sensible option is to go for the lesser S500, kicking off from £96,565, but there’s a definite appeal to this supercoupe.
In an effort to tidy up its model names, Mercedes has decided that the car previously known as the CL-Class will now be called the S-Class Coupe. As ever, there are tyre-smoking AMG models at the top of the range, and now we’ve had our first go in the S63 on British roads.
It sounds crazy, but this £124,715 twin-turbo V8-powered car isn’t the fastest or most expensive S-Class Coupe you can buy – that honour goes to the £183,000 V12 S65. Yet based on this first UK drive of the S63, there’s absolutely no need to upgrade.
Performance is utterly effortless, with 900Nm of torque available from as low as 2,250rpm. What that means for everyday driving is that whenever you put your foot down, there’s a seemingly endless supply of acceleration at your disposal. The hand-built 5.5-litre V8 also produces 576bhp, allowing for an official 0-62mph time of 4.3 seconds.
There’s a great understated burble from the exhausts at low revs, and more of an aggressive crackling note as they head towards the red line. You can hear it from inside the cabin, but it’s more background noise than anything else.
Being an S-Class, you’d expect a level of technical innovation from the S63, and it delivers it with something called Curve Tilt Function. This works with the Magic Body Control system (which uses cameras to set up the suspension for rough roads ahead) to actively lean against cornering forces. Pressing the air-suspension button twice activates it.
It’s definitely designed more for comfort than for handling. Going round a corner at 40mph feels more like taking it at 25mph because you’re not pulled against your seat quite so much, and you can feel it through the steering wheel, too – as it doesn’t weight up as much as you’d expect when turning.
With bespoke settings for the air-suspension, the S63 feels a little firmer than a standard S-Class Coupe, but with settings in Comfort it’s still one of the best riding cars out there. The switch to Sport immediately transmits more bumps into the cabin, but it does sharpen up the handling slightly. Don’t sit behind the wheel expecting it to feel like a lightweight sports car and you’ll be fine.
The S63 is more of a cruiser than it is a sports car, and in this respect it performs very well. The beautiful cabin is not only extremely elegant but it also has a seriously high-quality feel and the level of refinement is really impressive: not as good as an S500 Coupe, but as quiet and relaxing as you’re ever likely to want. And as standard you get adaptive cruise control with steering assist, which provides semi-autonomous driving. Set your distance and speed and the Coupe will brake and accelerate for you while keeping the car in its lane. Take your hands off the wheel and it’ll steer for you, too, before swiftly warning you to grip hold of the rim again.
But what don’t we like about the S63? Well, at this end of the price range, everything becomes relative. Yet no rivals can match the amount of innovation on offer in the S63 Coupe, which manages to deliver many of the S-Class saloon’s incredible abilities – both in terms of comfort and performance – while developing a real sense of style that outclasses it.
