A Mercedes spokesperson suggested that the concept, which was revealed at the Shanghai motor show last year, is more similar to the production version than the spy shots we’ve seen so far would suggest. The disguised GLC Coupé has the same swooping roof design as the concept, but with smaller wheels, and it features a similar front to its GLC sibling, aside from a different grille.
Engines for the GLC Coupé will be shared with the regular GLC, although Mercedes would not specify which engines would make it across. The GLC Coupé’s larger sibling, the GLE Coupé, carries over one petrol and one diesel V6 from its namesake, so it’s likely that one petrol and one diesel four-cylinder unit will be used in the GLC Coupé.
No official measurements for the production version are available, but at 4727mm long, 2000mm wide and 1593mm tall, the GLC Coupé concept was 57mm longer, 120mm wider and 28mm lower than the X4.
It also rode on a wheelbase that was 17mm longer than the BMW’s, at 2827mm. Compared with the outgoing GLK, it was 192mm longer, 160mm wider and 77mm lower.
The sporting SUV had a modified version of Mercedes’ modular high-strength steel MRA platform, as found beneath the latest C-Class. It was allied to aluminium-intensive suspension that uses a combination of double wishbones up front and multi-links at the rear.
Although it has not been officially confirmed, Autocar can reveal that production versions of the new swoopy-styled GLC Coupé will have the option of rear air springs, following the lead taken by the C-Class.
Power for the concept came from a twin-turbocharged 3.0-litre V6 petrol engine, one of a number of units that will be made available in the GLC and GLC Coupé, according to senior Mercedes sources.
The twin-turbo V6 kicks out 362bhp and 383lb ft of torque - 60bhp and 88lb ft more than the most powerful petrol-powered X4 model, the xDrive35i.
This particular engine is set to power a GLC450 Coupé AMG model, in line with moves made with the larger GLE450 Coupé Sport shown in 2015.
Channelling these reserves to all four wheels is Mercedes’ new nine-speed 9G-Tronic automatic gearbox and 4Matic four-wheel drive system.
Officials revealed in Shanghai that the company’s SUV line-up would eventually extend to seven models.
Included are the GLA, GLC, GLC Coupé, GLE, GLE Coupé, GLS and traditional G-Class, which is set to be substantially updated in 2017.
