Aimed at the BMW X4, Porsche Macan and upcoming Jaguar F-Pace, the high-riding five-door will initially be offered with the choice of a 2.0-litre petrol engine and a 2.1-litre diesel in two different states of tune. Prices are expected to start at around £38,000, a premium of around £3000 over the standard GLC.
Originally previewed as a lightly veiled concept at last year’s Shanghai motor show, it shares the GLC’s C-Class-based underpinnings and will be produced alongsideit at Mercedes’ Bremen plant in Germany.
The GLC Coupé shares its bonnet, front wings and lower door panels with the GLC, but it receives new, more sportily styled bumpers, a more heavily angled windscreen, a plunging roof structure with a large liftback-style tailgate and a significantly longer rear overhang than its more practical sibling.
In addition to the basic steel spring arrangement, the GLC Coupé comes with the choice of two suspension set-ups with variable damping control, including a new steel spring Dynamic Body Control set-up and the Air Body Control system with air springs already available on the regular GLC. The Coupé also has a lower ride height than the GLC.
At 4730mm long and 1600mm high, the GLC Coupé is 60mm longer and 30mm lower than the X4. It has a wheelbase that is 60mm longer than the BMW’s, at 2870mm (the same as the GLC SUV) and rides on wheels up to 20in in diameter.
Inside, the GLC Coupé receives the same C-Class-sourced interior set-up as the GLC, including a 40/20/40 split/folding rear seat.
At launch, the GLC Coupé will come with a choice of three engine options. The first is a turbocharged 2.0-litre petrol unit delivering 208bhp and 258lb ft in the GLC 250 4Matic Coupé. It is supported by a 2.1-litre diesel offering 168bhp and 295lb ft in the GLC 220 d 4Matic Coupé and a gutsier 201bhp and 369lb ft in the GLC 250 d 4Matic Coupé.
All models run Mercedes’ 9G-Tronic nine-speed automatic gearbox and 4Matic four-wheel drive as standard.
The performance leader of the early GLC Coupé line-up is the petrol-powered GLC 250 4Matic Coupé, which hits 62mph from rest in 7.3sec and a maximum speed of 138mph.
Shortly after its UK launch, the model will receive further engine options, including a more powerful version of the 2.0-litre petrol engine with 242bhp in the GLC 300 4Matic Coupé and a turbocharged 3.0-litre V6 diesel with 254bhp and 457lb ft in the GLC 350 d.
Also under development is a petrol-electric-powered GLC 350 e 4Matic Coupé plug-in hybrid model that is claimed to provide a zero-emissions range of up to 19 miles and a 0-62mph time of 5.9sec. It combines the GLC 250 4Matic Coupé’s 2.0-litre petrol engine and a gearbox-mounted electric motor for a combined system output of 315bhp.
Heading the line-up at first will be the GLC 43, the first of two planned AMG models. It runs a twin-turbo 3.0-litre V6 petrol engine with 362bhp and 383lb ft, which is sufficient to provide the GLC 43 with a claimed 0-62mph time of less than five seconds.
Mercedes-AMG sources have also confirmed to Autocar the existence of plans for an even more powerful GLC 63 4Matic Coupé. It will receive AMG’s twin-turbocharged 4.0-litre V8 petrol engine producing up to 503bhp.
In an effort to broaden the model’s appeal, Mercedes says it will, in time, offer the GLC Coupé in rear-wheel-drive guise and with a six-speed manual gearbox, although only with selected engines.
