In concept, I was undecided about the new Mercedes S-class coupé. It was a Mercedes CL by another name, and I couldn’t shake the hunch that its makers were trying to hoodwink me into thinking it was something more special with a simple nomenclature switch.

But now I’ve seen it, I understand. I understand why Mercedes' honchos have been talking about this car whilst hopping from foot to foot, so excited that they can’t stand still. I understand why it deserved this new name. I understand why this is now the most desirable Mercedes, bar none. At least until the GT AMG (or baby SLS, as we’ll call it for now) lands this summer.

By any measure, in the metal here on the eve of the Geneva motor show, the S-class coupé is a stunner. Its shoulder line is spectacular - bold yet sophisticated in a manner that makes you want one. The front sufficiently striking that you could park one next to an Aston Martin or Maserati and not feel remotely inferior. And the interior? Well, we’ve written enough superlatives about the innards of the Mercedes S-class in Autocar for you to get the picture.
