What is it?
The Mercedes-AMG GLC S 63 is the three-pointed star’s most powerful mid-sized performance SUV yet. It joins the model line-up above the existing Mercedes-AMG GLC 43 and goes into battle against the Porsche Macan Turbo and BMW X3 M40i – with a raft of rivals from the likes of Jaguar and Alfa Romeo looming in 2018.
Available to order now with first right-hand-drive UK cars due for delivery next spring, the GLC 63 is available in a choice of two body styles and in two states of tune. There’s a coupé variant that carries with it a price premium of almost £2500 over the standard body shape. Meanwhile, the faster, more powerful S derivative of each body style costs £6750 more than the standard versions.
The GLC 43 is something of a halfway house between the standard GLC model range and a full performance model out of AMG’s Affalterbach headquarters, but there are no such qualms with the GLC 63, which derives a lot of its technology from AMG’s staple models.
All the GLC 63 derivatives are equipped with the nine-speed automatic transmission that originally appeared in the Mercedes-AMG E 63, plus the latter car’s version of the 4Matic four-wheel-drive system. The new set-up uses an electro-mechanically controlled clutch to connect the permanently driven rear axle with the front axle and provide a fully variable apportioning of drive dependent on grip and traction.
