The rear of a camouflaged prototype of the Mercedes-AMG GLC 450 Coupe was caught on camera recently while it was going through tests, as shown on a report from worldcarfans.com.

Industry watchers have indicated that it may be impractical for the German luxury vehicle manufacturer to produce arrival to the BMW X4 by turning a GLC into a coupe. The slope on its roofline will have an adverse effect on the headroom at the back along with the capacity of its trunk. This is noticeable when the GLE is compared to the GLE Coupe. The GLC 450 Coupe is set to occupy a niche in the market right under the Mercedes-AMG GLC 63 Coupe.

In addition to the quad exhaust tips, the Mercedes-AMG GLC 450 Coupe will also feature a rather aggressively-designed body, bespoke wheels, bigger engine, larger brakes and a more rigid suspension. It will also feature a bi-turbo 3.0-liter V6 engine offering 362 HP of power and torque of 384 lb-ft. The power and torque are sent through the 7-speed automatic transmission system into its 4MATIC all-wheel drive system. While the C450 Sedan, featuring the same hardware, is capable of accelerating from 0 to 60 mph with 4.8 seconds the weight of the GLC 450 Coupe slows down its acceleration to around 5 seconds.

The Mercedes-AMG GLC 450 Coupe is expected to be officially unveiled in March during the Geneva Motor show together with the GLC Coupe. On the other hand, the range-topping Mercedes-AMG GLC 63 Coupe will not see the light of day until 2017. It features a 4.0-liter bi-turbo V8 engine offering 469 HP of power for the standard model while the S model offers 503 HP of power.
