Price, fuel economy, range and depreciation

Having gone through the Affalterbach skunkworks that is AMG, this particular GLC Coupé bears a far loftier price than its more pedestrian range-mates. Where the standard GLC220d Coupé costs from £42,365, the GLC63 S Coupé is priced from £78,560. Ours came in at £90,925 after options.

That makes it significantly more expensive than two of our favourite fast SUVs: the £63,981 Macan Turbo and £69,500 Stelvio Quadrifoglio. They outshine the GLC in the depreciation stakes, too, with the Stelvio expected to retain 58% of its value after 36 months and 36,000 miles and the Macan 63%. The GLC63 S, meanwhile, manages just 52%.

Forecasts aren’t terrible for the Merc, but it’s outdone by the Porsche by a huge margin and, interestingly, the Alfa too.

Standard kit is respectable, though. In addition to that thunderous V8, the Mercedes gets a sports exhaust, 20in alloy wheels, a 360deg parking camera, heated AMG performance seats, 8.4in infotainment system with navigation, DAB radio and Bluetooth connectivity, and more besides.

The £12,365 of options on our test car included the £2395 Premium Pack, which adds a Burmester sound system and glass sunroof, £4285 ceramic-composite brakes, and the £1695 Driving Assistance package with safety features such as active blindspot and lane keeping assist.
