What’s the point?
Audi and Mercedes would insist the A7 and CLS are models in their own right, when in reality they’re basically swoopier, more style-lead and (supposedly) more dynamic versions of their existing saloons. The old A7 was based on the A6, but this new one shares a chassis, much of its technology and 48-volt mild-hybrid powertrains with the new A8. It’s gone up in the world, you might say.
The CLS, however, remains an E-Class underneath, as indeed it always has been since it gave birth to this whole swoopy four-door coupe thing back in 2004. So the two kinda meet in the middle now, at £60k or thereabouts if you factor in options. Which you most definitely should because they ratchet up the value somewhat.
As tested, both are six-cylinder, 3.0-litre diesels, all-wheel drive and automatic of gearbox. Eight speeds in the Audi, nine in the Merc. The Merc is an AMG-Line – the only trim available in Britain – and the Audi an S-Line. It’s £66,140 for the Merc as-tested, and £66,350 for the Audi.
