Mercedes-Benz celebrates the 50th anniversary of its Mercedes-AMG performance division at the Detroit show with the unveiling of a new coupé model.

The Mercedes-AMG GT C Coupé is effectively a hard-top version of the already launched AMG GTC Roadster. It will join the range between the GT S and GT R models, extending the Mercedes-AMG line-up to six models.

Initial examples will be sold as special ‘Edition 50’ models to celebrate the golden jubilee of Mercedes-AMG.

The Mercedes-AMG GT C Coupé borrows several elements from its more expensive GT R sister, including the wider and more muscular rear end, extended by 57mm over the GT and GT S versions. The GT R’s rear axle steering is also fitted – aiding handling, it turns in the opposite direction as the front axle at speeds under 62mph, and in the same direction at higher speeds.

Power for the Coupé comes from the same 4-litre V8 petrol engine as in other GT variants, in the GT C roadster specification with 557hp and 680Nm of torque. Despite weighing 35kg more than the roadster the Coupé returns the same 0-62mph time of 3.7 seconds and will go on to 196mph.

Two colours for special edition

Edition 50 will be offered in two bespoke paint finishes: designo graphite grey magno and designo cashmere white magno. Both versions include black chrome highlights on the side skirt trim, the front splitter, the air inlet trim strips in the grille, the side air outlet fins in the front wings, the rear diffuser moulding and the exhaust tailpipe trims. The surfaces of the cross-spoke AMG forged wheels gain a similar treatment.

Inside there is silver pearl/black nappa leather with grey diamond-patterned contrasting top stitching, and a black steering wheel with grey contrasting top stitching. The AMG Interior Night package is fitted as standard – steering wheel spokes, shift paddles and door sill panels are finished in black, along with silver seat belts and black chrome trim.

Power gains across range

Meanwhile other GT models are gaining upgrades. The entry-level GT’s power goes up from 462 to 476hp and it also gets an extra 30Nm of torque. The GT S gains 12hp (522hp) and 20Nm.

Further changes see the Airpanel active air management system, standard on the range-topping 585hp GT R, being extended to all GT variants. An electric motor opens and closes vertical shutters in the grille, at one-second intervals, to constantly prove the exact amount of cooling needed.

UK prices of the Mercedes-AMG GT C Coupé are due to be announced shortly – first deliveries are set for summer 2017.
