Mercedes-AMG is extending its sports car portfolio with the new AMG GT S Roadster as an attractive open-air model.

With this latest addition the AMG GT family now has a dozen members: four two-door Coupés, three Roadsters, two customer sports racing cars and three four-door Coupés.

The basis for the high driving performance of the new AMG GT S Roadster is the combination of a lightweight aluminium spaceframe, a V8 biturbo engine, a seven-speed dual clutch transmission, a rear axle locking differential and a sport suspension with aluminium double wishbone axles.

Compared to the AMG GT Roadster, the AMG GT S Roadster is rendered even more dynamic by numerous modifications to the engine, suspension, brakes, design and interior.

This positions it between the AMG GT Roadster and the even more powerful AMG GT C Roadster, now providing a choice of three open- top two-seaters.

The AMG 4.0-litre V8 biturbo in the AMG GT S Roadster delivers an output of 384 kW (522 hp) and maximum torque of 670 Nm. This is available over a wide engine speed range from 1900 to 5000 rpm. The eight-cylinder power unit delivers a sprint from standstill to 100 km/h in 3.8 seconds. The dynamic power delivery continues right up to the top speed of 308 km/h.

The two turbochargers of the V8 are not positioned on the outside of the cylinder banks, but inside the cylinder V. Advantages: a compact engine design and spontaneous response of the turbochargers.

Power transfer is based on the combination of a front mid-engine and the AMG SPEEDSHIFT DCT 7G sport transmission in a transaxle arrangement, combined with a torsionally-rigid torque tube. Thanks to the wide gear ratio spread, the decidedly high torque of the V8 biturbo engine can be used to optimum effect. The weight distribution is also ideal for optimum driving dynamics at 47 (front) and 53 (rear) percent.

The driver is able to set the AMG GT S Roadster to his or her individual requirements using the AMG DYNAMIC SELECT controller. Five drive modes, C (Comfort), S (Sport), S+ (Sport Plus), RACE and the individually programmable setup I (Individual) are available. These allow a broad range of driving experiences - from comfortable to very sporty.

By pressing the separate M button in the centre console, the driver can activate the manual transmission mode in any drive mode to change gear using the steering-wheel shift paddles.

For the body of the GT S, Mercedes-AMG has opted for an intelligent and particularly lightweight mix of materials with a high proportion of aluminium.

The three-layered fabric soft top is supported by a magnesium/steel/aluminium structure of low weight, which helps to keep the vehicle’s centre of gravity low. Additional roll-over protection is provided by an integrated aluminium cross- member, while the inserted acoustic mat improves noise comfort.

From the expressive AMG radiator grille to the long bonnet and the muscular tail end, the two-seater guarantees a pure sports car experience even when stationary, its designers say.

The flat front section and forward-sloping radiator grille make the Roadster appear to hug the road. At the same time this shape lowers the vehicle’s back-pressure point, enhancing the flow of cooling air and the car’s aerodynamic performance.

Viewed from the side, the arched roof line (when the soft top is closed) and the frameless doors are eye-catching features. The surfaces and lines of the side wall flow into the tail end with a dramatic tapered effect.

The active air regulation system AIRPANEL included as standard is a particular technical highlight. Vertical louvres at the bottom of the front apron are opened and closed electronically by means of an electric motor in around one second to guarantee the required amount of cooling.

As another active aerodynamic component the Roadster features an extendable rear spoiler. This reduces lift at the rear axle at higher speeds. With its broad shoulders and expressive tail light graphics, the rear end enhances the emotional overall appearance.

The interior design echoes the design lines of the exterior. The dashboard places a firm emphasis on width, creating an impression of a powerful wing. Thanks to the high beltlines, concave door panelling, a dynamic, rising centre console and the low seating position, the driver is integrated into the cockpit and feels fully attuned to the Roadster.

Prices will be announced soon. For more details contact Al Haddad Motors on 17785454.
