2018 Mercedes-AMG S63 Summary

Ever since the middle of the 1990s, I've been captivated by the Mercedes-Benz S Class. It used to be known as Sonderklasse - special class - and teenage me certainly thought it was. The one that caught my attention was the W140. A huge, two-tonne beast when that sort of mass was rare, it was loaded with amazingness and owned the road.

Part of its unique appeal was that that it was properly ugly. When it hove into view it was like a battleship entering Sydney Harbour. And it used almost as much fuel, with the V12 on board.

Over the years, genuine style has invaded the S-Class and today I found myself, for the first time, in an unusually pretty pair of S Classes - the S560 and S63 Coupes. And, astonishingly, it's the first time I've ever driven an S-Class. So with all that baggage I've built up over the years, they had a lot to live up to.

2025 BMW M235i Summary

Sometimes a name change can make all the difference.

Google used to be called “Back Rub”. The Spice Girls started off as “Touch”. And – particularly in Germany – some premium sedans became known as “coupes”, as they struggled to stay popular against SUVs.

Case in point: what is essentially a 1 Series hatchback with a boot has been more glamorously badged the “2 Series Gran Coupe” since 2020.

Still following the sedan script with four doors, it’s BMW’s tilt at Mercedes’ booted A-Class hatch, the rakish CLA, unveiled early last decade as the Concept Style Coupe and now in its third series-production iteration – though since 2019 a more conservatively styled A-Class Sedan has also existed, that goes up against Audi’s A3 Sedan.

But we digress. Now there’s a “new” 2 Gran Coupe, coded F74, though it’s really a heavy facelift of the superseded F44. Oh, and the ‘i’ no longer exists in the badge, so (M-enhanced models aside) it’s just numbers from here on in. 218. 220. M235.

Regardless of names, does it live up to the BMW promise?
