An attractive open-air vehicle is joining the Mercedes-AMG sports car family, the AMG GT S Roadster. This addition means that the AMG GT roster 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 bi-turbo engine, a seven-speed dual clutch transmission, a rear axle locking differential, and a sport suspension with aluminium double wishbone axles. Modifications to the engine, suspension, brakes, design and interior make the GT S Roadster more dynamic than the GT Roadster.
The 4.0-liter V8 bi-turbo bring 522 hp and a maximum torque of 670 Nm. The GT S Roadster goes from standstill to 100 km/h in 3.8 seconds and its dynamic power delivery continues right up to the top speed of 308 km/h. The two turbochargers are positioned inside the cylinder, “V”, to make the engine more compact and ensure a spontaneous response.
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 bi-turbo engine can be used to optimum effect. The weight distribution is also ideal for optimum driving dynamics at 47 (front) and 53 (rear) percent.
Thanks to the AMG RIDE CONTROL suspension with adaptive damping adjustment as standard, the AMG GT S Roadster’s wheel damping is adjusted at each wheel to the current requirements. This improves driving safety and ride comfort. The ideal operating point can be selected at all times on the basis of extensive information relating to acceleration or vehicle speed, for example.
The AMG DYNAMIC SELECT controller offers the driver 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. And, by pressing the separate “M” button in the center console, the driver can activate the manual transmission mode in any drive mode to change gear using the steering-wheel shift paddles.
An electronically controlled locking differential at the rear axle, which is integrated into the compact transmission housing, raises the critical limit of vehicle dynamics to a new level. It not only further improves the traction of the drive wheels, but also increases the critical cornering speed. The greatest benefit of the electronic rear-axle limited-slip differential is the even more sensitive and proactive control, which pushes the critical threshold higher, making it even easier to drive at the vehicle’s limits.
The AMG high-performance composite brake system is adapted to the enhanced performance of the AMG GT S Roadster. The front axle features composite brake discs measuring 390 x 36 mm with 6-piston fixed callipers, with composite brake discs measuring 360 x 26 mm and single-piston fixed callipers at the rear. The brake callipers are painted in red with “AMG” lettering.
There is also the option of the AMG high-performance ceramic composite braking system with brake discs in size 402 x 39 mm at the front axle and 360 x 32 mm at the rear, together with specially painted brake calipers with “AMG Carbon Ceramic” lettering. Exceptionally short stopping distances, a precise pressure point and outstanding resistance to fading even under extreme operating conditions.
The AMG GT S Roadster’s 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 paneling, a dynamic, rising center console and the low seating position, the driver is integrated into the cockpit and feels fully attuned to the Roadster.As standard the AMG GT S Roadster comes with the AMG Silver Chrome Interior package. This creates particular highlights with trim in high-quality silver chrome.
Mercedes-AMG’s GT S Roadster offers extensive standard equipment. On this basis, the car offers a wide scope for individual wishes. The AMG DYNAMIC PLUS package ensures even higher driving dynamics and even sportier handling characteristics.
As an option the AMG rear axle steering can be ordered in conjunction with the AMG DYNAMIC PLUS package. This makes the AMG GT S Roadster even more agile, with even greater handling stability at the limits.
