The 2017 Detroit motor show has played host to the debut of the updated 2017 Mercedes-AMG GT range, as the sporty arm of the German company celebrates 50 years.

The Mercedes-AMG GT range has expanded to include a new coupe derivative, the Mercedes-AMG GT C – there was already a convertible (Roadster) version, but apparently there was demand for it in the hard-top range, too.

The new wide-body AMG GT C is positioned to sit above the GT S and below the hardcore GT R, and from launch it will be sold as the Edition 50 variant pictured below – more on that in a sec.


But before we get to the details of the Edition 50, there’s good news for the rest of the Mercedes-AMG line-up – the range has been facelifted, and there’s even more power, too.

The 4.0-litre twin-turbocharged petrol V8 engine in the GT model now churns out 350kW of power, up 10kW, while torque has been tickled up by an extra 30Nm to 630Nm. This version – with or without roof – has a claimed 0-100km/h time of 4.0 seconds. The Roadster has a slightly lower top speed of 302km/h, where the coupe can do 304km/h.


The powerplant in the GT S model has seen a 9kW jump to 384kW, while torque for that version is up 20Nm, to 670Nm. The GT S is claimed to do the benchmark sprint in just 3.8sec, on its way to a top speed of 310km/h.

The GT C versions of the Mercedes-AMG coupe and convertible models have 410kW of power and 680Nm of torque, with claimed acceleration of 3.7 seconds in either body-style, and its top speed is 317km/h for the coupe and 316km/h for the drop-top. The GT C models have active rear-wheel steering, just like the GT R model.

The flagship GT R version continues with 430kW/700Nm (is that all?!), and does the mumbo in 3.6sec, on its way to a 318km/h top speed.

All variants of the AMG GT model range remain available only with the brand’s seven-speed dual-clutch automatic gearbox, and they’re all still rear-wheel drive.


All models have a rear differential lock (the GT models’ being mechanical, while all other versions have an electronic locking system), and the base model car has standard sports suspension while the higher-spec models get AMG Ride Control adaptive damping. The GT also misses out on the Race drive mode the other models get.

Visually, the 2017 Mercedes-AMG GT gets a revised grille – the AMG Panamericana grille, to be precise – which has 15 chrome-plated vertical bars, and there’s a new front apron that has been designed to make the car look wider and appear to sit flatter on the road.

The company’s Airpanel active air intake system with electric louvres is now fitted to all models, not just the top-spec GT R. They open up to allow more air into the engine when needed, or remain closed under easier driving.


To fill the wider rear guards – they’re pumped by 57 millimetres compared to the GT S and GT models – the GT C has wider wheels than the GT S, 20-inches by 12 across the tread, not 11. And in Edition 50 it will be available in two special paint finishes: Designo Graphite Grey Magno and Designo Cashmere White Magno.

The GT C Edition 50 has black chrome highlights to its side skirts, front splitter, trim strips and fins, as well as its exhaust trims.

Inside, the GT C Edition 50 has a contrasting black-on-silver trim, finished in Nappa leather and with a Dinamica microfibre steering wheel. There are a few Edition 50 model references littered through the cabin, too.

According to Mercedes-Benz Australia, the first customer orders for the updated Mercedes-AMG GT models will arrive in the third quarter of 2017.

At that time, Mercedes-Benz Australia will also launch the new AMG GT Roadster and GT R coupe models.
