AMG GT Roadster and AMG GT C Roadster

Mercedes-AMG is blowing even more fresh air into the AMG GT family. Shortly after the world premiere of the AMG GT R, the sports car and performance brand from Affalterbach is presenting two exciting roadster variants of the two-seater sports car. Alongside the AMG GT Roadster, the AMG GT C Roadster enhances the portfolio with a completely new model variant. With an output of 410 kW (557 hp) and peak torque of 680 Nm (502 lb-ft), the AMG GT C is the most powerful new Roadster variant and uses some of the technical refinements of the AMG GT R. These include active rear axle steering and the electronically controlled rear axle locking differential. In combination with the AMG RIDE CONTROL sports suspension, the AMG GT C Roadster guarantees dynamic performance at the highest level. The top Roadster also takes its lead from the top AMG GT R sports car where muscular proportions are concerned: the wider rear wings create space for a wider track and wider wheels at the rear axle, allowing even higher cornering speeds and best traction. The variable performance exhaust system also ensures an authentic V8 sound from the AMG Roadster.Mercedes-AMG GT Roadster (R 190), 2016

The new Roadsters make hallmark AMG driving performance an even more intensive experience. “With our two Roadster models, we are strategically expanding the AMG GT family by two exciting variants. With the AMG GT C Roadster, we are also introducing a new model variant to which we have transferred main performance-related components from our top sports car, the AMG GT R. The result: a highly dynamic driving experience in a very exclusive ambience, coupled with that pure roadster feeling,” says Tobias Moers, Chairman of Mercedes‑AMG GmbH.

With the two Roadster variants, the Mercedes‑AMG GT family has now increased to five members. The two new sports cars with fabric soft tops likewise have the technical genes for which AMG is famous. These include e.g. the lightweight and torsionally rigid aluminium bodyshell plus powerful and efficient V8 biturbo engines. The entry level into the Roadster world is the AMG GT with an output of 350 kW (476 hp). The GT C Roadster adds a completely new output level. With 410 kW (557 hp) it is the more powerful of the two new open-top sports cars.

Mercedes-AMG GT Roadster (R 190), 2016The AMG GT C Roadster not only delivers more output and torque, it also impresses with numerous technical highlights from the Mercedes‑AMG GT R for even more dynamic performance. Like the AMG GT R, the AMG GT C Roadster is recognisable by its wide, muscular rear end and large wheels. Other technical measures include the wider rear track and active rear axle steering.Mercedes-AMG GT Roadster (R 190), 2016

The AMG GT C Roadster is also equipped with a lithium-ion battery, and has more exclusive appointments. Standard features include a nappa leather interior, the AMG performance steering wheel in nappa leather/DINAMICA microfibre and the additional transmission mode RACE.

Fully automatic: the weight-optimised fabric soft topMercedes-AMG GT C Roadster (R 190), 2016

Both Roadsters are quickly transformed from coupés to open-top sports cars. The fabric roof opens and closes in around eleven seconds, and can do this at speeds of up to 50 km/h (31 mph). The three soft top colours black, red and beige can be chosen to suit the eleven exterior and ten interior colours. The three-layered fabric soft top is supported by a magnesium/steel/aluminium structure of low weight, which helps to keep the centre of gravity low. Additional rollover protection is provided by an integrated aluminium cross-member with rollover bars.

New output level: the AMG 4.0-litre V8 biturbo engine

With the AMG GT C Roadster, Mercedes-AMG is introducing a further output level of the 4.0-litre V8 biturbo, thereby underlining the exclusive character of the new model. At 410 kW (557 hp), the peak output is 35 kW (47 hp) above that of the AMG GT S and 20 kW (28 hp) below the Mercedes-AMG GT R. The maximum torque of 680 Nm (502 lb-ft) is available from 1900 to 5750 rpm. A sprint from zero to 100 km/h (62 mph) is absolved in 3.7 seconds, and this fulminating acceleration only ends at the top speed of 316 km/h (196 mph).

The AMG GT Roadster has an output of 350 kW (476 hp) and 630 Nm (465 lb-ft) of torque. This variant accelerates to 100 km/h in 4.0 seconds, and has a top speed of 302 km/h (188 mph).Mercedes-AMG GT Roadster (R 190), 2016

The eight-cylinder engine thrills with its immediate response, a linear, finely controllable power delivery and powerful acceleration in all rpm ranges. The AMG 4.0-litre V8 comes with well-proven twin turbocharging, with the two chargers not located outside on the cylinder banks, but rather between them in the V of the cylinders. The advantages of the “hot inner V”: a compact engine design, spontaneous response from the turbochargers and low exhaust emissions thanks to optimum air flow for the close-coupled catalytic converters.

Also adapted: the dual-clutch transmissionMercedes-AMG GT Roadster (R 190), 2016

The developers have also adapted the seven-speed dual clutch transmission in a transaxle arrangement at the rear axle to the new power level of the Mercedes‑AMG GT C Roadster by modifying the hardware and software. The first gear of the AMG SPEEDSHIFT DCT 7-speed sport transmission has a higher ratio, while seventh gear and the final drive have a lower ratio. This makes for even more agile acceleration and very fast responses to sudden accelerator movements.Mercedes-AMG GT (C 190) 2014

The driver is able to set the AMG GT Roadster to his/her individual requirements using the AMG DYNAMIC SELECT controller. The three transmission modes “C” (Comfort), “S” (Sport), “S+” (Sport Plus) and the individually programmable setup “I” (Individual) allow a broad range of driving experiences from comfortable to very sporty.

The transmission mode “RACE” is additionally available for the Mercedes-AMG GT C Roadster. This mode optimally adjusts the shift strategy of the dual clutch transmission to the needs of the racetrack – very fast shift speeds and highly emotive engine sound are included. By pressing the separate “M” button in the centre console, the driver can activate the manual transmission mode in any drive mode.

Pure sound: the AMG performance exhaust systemMercedes-AMG GT C Roadster (R 190), 2016

The AMG GT C Roadster is equipped with the AMG performance exhaust system as standard to obtain an even more emotive sound experience. Two variably adjustable flaps modulate the exhaust note of the Mercedes-AMG GT C Roadsters authentically and directly. The flaps open and close depending on the selected AMG DRIVE SELECT mode, although they can also be controlled individually using a separate button in the AMG DRIVE UNIT. In the “Comfort” and “Sport” settings, the low-frequency sound typical of a V8 is designed for comfort. In “Sport Plus” and “RACE” modes the sound composition is far more emotive. The variable AMG performance exhaust system is also available as an option for the Mercedes-AMG GT Roadster.

Also for the Roadster models: active air management system from the AMG GT RMercedes-AMG GT Roadster (R 190), 2016

The two AMG Roadster variants have adopted a special technical highlight from the AMG GT R: the active air management system. Vertical louvres located in the lower area directly behind the front fascia can be opened and closed by an electric motor in around one second. This ensures that the cooling performance is according to need. Always achieving the optimum position requires highly intelligent and fast control.

During normal driving with no increased cooling requirement, the louvres are closed to reduce aerodynamic drag and specifically conduct the air to the underbody. Only when certain components reach predefined temperatures and the air requirement is particularly high do the louvres open to allow the maximum cooling airflow to the heat exchangers.
