Debut next year at the Geneva Motor Show.

One of our readers from Germany has spotted a partially camouflaged prototype of next year's Mercedes-Benz GLC Coupe.

Developed to go head to head with the BMW X4, Mercedes-Benz's "coupe" version of the new GLC compact crossover will be out early next year, but until then it has to undergo a series of tests and in these spy pics we see a prototype on the German autobahn near Stuttgart. You will notice there's camouflage only on the rear of the car, but that shouldn't come as a surprise since the front half will be virtually identical to the regular GLC. It's the same story with the larger GLE & GLE Coupe duo and most likely Mercedes will do the same thing with the GLS Coupe and the rumored GLA Coupe (based on the second-gen).

The Daimler-owned marque already showed us a GLC Coupe concept earlier this year at Auto Shanghai and we estimate the production car will stay very close to the concept, albeit without the Lexus-like stacked exhaust pipes and the recessed door handles. It will also have less flashy bumpers and a set of more conventional side mirrors, but other than that it will remain just about the same.

As far as the engine lineup is concerned, it will be carried over from the regular GLC, including the frugal plug-in version and the range-topping AMG model which will likely be available right away.

Expect the Mercedes-Benz GLC Coupe to show up March next year at the Geneva Motor Show and go on sale right after that at a price tag slightly higher than the equivalent GLC.
