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 sportscars. And only 750 people in the world will get to own one of these cars.

The new GT R is aimed at a lifestyle-oriented target group who want exclusivity with their brand-defining sportscar. And like the other roadster models, the open GT R also has the triple-layer fabric soft top with a lightweight structure consisting of aluminium, magnesium and steel.

0 – 100 km/h in 3.6 seconds
Under the bonnet is an AMG 4.0-litre V8 biturbo which generates 585 ps/700 Nm, with the maximum torque available from 2,100 to 5,500 rpm. The muscular 8-cylinder power unit can propel the car from standstill to 100 km/h in a claimed 3.6 seconds and keep rocketing it to a top speed of 317 km/h.

The low-slung front section and the forward-inclined AMG-specific radiator grille create a distinctive “shark nose” impression and make the car appear to sit lower on the road. The V-shaped arrow-like appearance of the front end also enhances the dynamic looks, thus embodying the uninhibited forward thrust of the GT R Roadster even before it moves.

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. For this reason, they sport two aerodynamically shaped horizontal fins in place of meshes and as a result route the airflow to the radiators without loss.

Additional Air Curtains on the outside of the front apron calm the airflow, improving the Cd value of the two-seater. Thanks to their narrow, vertical openings, the Air Curtains also guide the air specifically towards the wheel arches, optimising the flow properties. To ensure ideal airflow through the double wheel arch radiators, the roadster additionally features unique wheel arch liners with special cooling-air slits.

Sucked to the road
An active aerodynamics profile is concealed almost invisibly in the underbody in front of the engine. Weighing around 2 kgs, this light carbonfibre element is speed-sensitive and automatically extends around 40 mm 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 kgs at 250 km/h.
