It’s got a dirty suspension secret
The S-Class Coupe is available with the S-Class saloon’s Magic Body Control, which scans the road head and sets up the suspension according to incoming bumps. It will also lean into corners like a high-speed train to tuck the centre-of-gravity as close as possible to the apex.
Thanks to the chassis reinforcements and roof mechanism, the S-Class Cabriolet is available with…neither of these things, Happily, it rides perfectly comfortably without them. It’s not as if you’re short of gadgets to show off, anyway.
