A camouflaged prototype of the Mercedes-Benz GLC has been spotted testing on a banked track.

Chances are the second generation GLK (to be commercialized as the GLC) was being put through its paces on Mercedes-Benz's oval test track located in Stuttgart which is 3 km (1.86 miles) long and has a 90-degree banked turn at the north west end. As for the car, it will be known as the GLC in order to better reflect its connections with the similarly-sized C-Class and as you can see it will drop the boxy shape in favor of a more curvaceous body.

Underneath the skin it will essentially be a C-Class but transformed into a crossover and set to grown in size compared to the first-gen in order to better distance itself from the GLA which now serves as Mercedes-Benz's entry-level high-riding model. Engines will be sourced from the C-Class, all the way up to a twin-turbo V8 4.0-liter which will power the GLC 63 AMG.

The model is codenamed X253 and is expected to spawn a BMW X4-rivaling GLC Coupe (C253) set to be introduced several months after the regular model's arrival in September 2015 at the Frankfurt Motor Show while AMG versions of both body styles are expected to follow shortly.
