Mercedes-AMG S63 vs Denza B8

What's the difference?

Both of these vast vehicles are phenomenally comfortable - this is the kind of car that Mercedes does so well, and has done for decades. The S Class is rarely a disappointment but it's difficult to believe that such a big, heavy GT car can also dance the way the S63 does.

The S560 is far more weighted to being a GT - supremely comfortable with that active suspension, a growly, refined V8 and a cabin full of gadgets and comfort. The S63 is altogether more aggressive, to look at and to drive. Lopping the roof off both of them adds weight but, like any cruiser, also puts you out in the sun, the breeze and into your surroundings. Plus, in the case of the S63, you get more exhaust noise.

They're two very different cars and not just because of the engine. After all these years admiring it from afar, the S63 has delivered on my teenage expectations - fast, smooth and utterly mad.

The Denza B8 6S is a luxurious and well-equipped entry into the upper-large SUV segment, with space, comfort and technology that make it a serious contender. Even in six-seat form, it delivers strong family practicality and a level of kit that will appeal to buyers looking for something different in this space.

While the driving experience isn’t always fully convincing, particularly in terms of refinement and handling, its pricing and overall package do a lot of the heavy lifting.

On that basis, it’s a newcomer the established rivals will be wise to keep an eye on.
