Mercedes has added a new uprated version of its GLC SUV to the range with some help from tuning arm AMG.

The new Mercedes-AMG GLC 63S ditches its predecessor’s memorable 4.0-litre bi-turbo V8 in favour of a radically different 2.0-litre turbocharged four-cylinder petrol engine. Billed as the first performance hybrid SUV, it’s a model which develops 670bhp and 1,020Nm of torque – significantly more than the 604bhp and 850Nm you would’ve found in the car it replaces.

Mercedes also claims a 0-60mph time of 3.3 seconds and a top speed of 171mph.

A less powerful GLC 43 will also be available. Acting as an entry point to the AMG GLC range, this uses a lower-output 2.0-litre turbocharged petrol engine, which here develops 415bhp. It’s integrated with a mild-hybrid system, which helps to boost power while also making the start-stop system a little smoother. Still, this version can manage the 0-60mph sprint in 4.6 seconds and carry on to a top speed of 155mph. It too features four-wheel-drive and a nine-speed automatic gearbox.

It’s expected that Mercedes will announce an official on-sale date for the AMG GLC shortly, along with pricing and specifications.
