Mercedes-AMG GT S Roadster, 192 mph soft-top

Mercedes-AMG has released a new rag-top, the AMG GT S Roadster. The new AMG GT S Roadster combines a lightweight aluminum spaceframe, a Handcrafted AMG 4.0-liter V8 biturbo engine, a seven-speed dual clutch transmission, a rear axle locking differential and a sport suspension with aluminum double wishbone axles.

"With the AMG GT S Roadster, our AMG GT family has gained another exceptionally sporty member that combines high driving dynamics with an emotional open-air experience," says Tobias Moers, Chairman of
Mercedes-AMG GmbH. "The new model represents the perfect alternative for the performance-oriented AMG GT Roadster customer."

Compared to the AMG GT Roadster, the AMG GT S Roadster boasts 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 two-seater roadsters.

The Handcrafted AMG 4.0-liter V8 biturbo in the AMG GT S Roadster delivers an output of 515 hp and maximum torque of 494 lb-ft. This is available over a wide engine speed range from 1,900 to 5,000 rpm. The eight-cylinder power unit delivers muscular performance in all engine speed ranges, combined with high efficiency for low fuel consumption and emission levels. A sprint from standstill to 60 mph is absolved in an estimated 3.7 seconds and the dynamic power delivery continues right up to the top speed of 192 mph.

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, spontaneous response of the turbochargers and low exhaust emissions thanks to optimal airflow to the near-engine catalysts. The dry sump lubrication also ensures the oil supply even with high lateral forces and allows the engine to be installed lower, thus moving the center of gravity closer to the road and forming the basis for high lateral acceleration.

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 percent (front) and 53 (rear) percent.

AMG RIDE CONTROL suspension with adaptive damping adjustment as standard. This fully automatic, electronically controlled system adjusts the damping at each wheel to the current requirements. This improves driving safety and ride comfort. The damping is adjusted individually for each wheel, and depends on the driving style, the road surface and the selected suspension setting. The ideal operating point can be selected at all times on the basis of extensive information relating to acceleration or vehicle speed, for example. Using a switch in the center console or by selecting the drive mode, the driver is able to choose between the different damping characteristic maps "Comfort," "Sport" and "Sport+," and can thereby individually influence the driving experience.

The AMG high-performance composite brake system is adapted to the AMG GT S Roadster. The front axle features composite brake discs measuring 15.4 x 1.42 in with 6-piston fixed calipers, with composite brake discs measuring 14.2 x 1.02 in and single-piston fixed calipers at the rear. The brake calipers are painted in red with "AMG" lettering. There is also the option of AMG high-performance ceramic composite braking system with brake discs in size 15.8 x 1.54 in at the front axle and 14.2 x 1.26 in 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 high-performance ceramic composite braking system offers motorsport-like braking performance and weighs around 40 percent less than with conventional composite brake discs.

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. The sports seats, the Performance steering wheel and the instrument cluster also demonstrate outstanding precision and high-quality materials.

The Mercedes-AMG GT S Roadster will be available in U.S. dealers by late 2018. Additional details including pricing will be available closer to launch.
