2019 Geneva Motor Show: Mercedes-AMG GT R Roadster

By THOMAS HUONG | 5 March 2019


GENEVA: The Mercedes-AMG GT R Roadster is limited to 750 units, and we take our hats off to this beast of the green hell.

Mercedes-AMG is combining its top model brimming with motorsport technology with the freedom of the open-air driving experience – crowning the model portfolio of open-top sports cars.

The new AMG GT R Roadster is just as much at home on winding racetracks as it is on prestigious boulevards or beautiful coastal roads.

The 585hp V8 biturbo, the adjustable coil-over suspension with active rear axle steering, the active aerodynamics and the intelligent lightweight construction provide highly dynamic handling characteristics.

And like the other roadster models, the open AMG GT R also has the triple-layer fabric soft top with a lightweight structure consisting of aluminium, magnesium and steel.

The AMG 4.0-litre V8 biturbo in the AMG GT R Roadster delivers an output of 585hp and maximum torque of 700 Nm.

This is available over a wide engine speed range from 2100 to 5500 rpm.

A sprint from standstill to 100kph is absolved in 3.6 seconds.

The low-slung front section and the forward-inclined AMG-specific radiator grille create a distinctive “shark nose” impression

It has standard-fit LED High Performance headlamps while a tri-functional, arched light guide takes on the functions of daytime running light, navigation light and turn signals.

The V-shaped arrow-like appearance of the front end also enhances the dynamic looks, while the front apron in jet wing design and the front splitter emphasise the car’s width.

The large outer air inlets in the front apron guarantee the increased supply of cooling air to the engine.

Additional Air Curtains on the outside of the front apron calm the airflow, improving the Cd value of the open-top two-seater.

An active aerodynamics profile is concealed almost invisibly in the underbody in front of the engine.

Weighing around two kilograms, this light carbon-fibre element is speed-sensitive and automatically extends around 40 millimetres downwards depending on the drive programme.

This process involves considerable change in the airflow and results in what is known as the Venturi effect, which additionally “sucks” the car onto the road and reduces the front-axle lift by around 40 kilograms at 250kph.

The aerodynamics profile automatically retracts again depending on the drive programme and speed.
