Mercedes-AMG is blowing even more fresh air into the AMG GT family. The sports car and performance brand from Affalterbach has launched two exciting roadster variants of the two-seater sports car into the region. Alongside the AMG GT Roadster, the AMG GT C Roadster enhances the portfolio with a completely new model that, with an output of 410 kW (557 hp) and peak torque of 680 Nm, also makes it the most powerful. The active rear axle steering and the electronically controlled rear axle locking differential, in combination with the AMG RIDE CONTROL sports suspension, ensures the AMG GT C Roadster delivers dynamic performance at the highest level.

“The AMG GT Roadster and the AMG GT C Roadster models expands the AMG GT family, adding a new level of sportiness and exclusivity between the AMG GT S and the AMG GT R,” said Lennart Mueller-Teut, Head of Marketing & Communications, Mercedes-Benz Cars Middle East. “Both Roadsters are the perfect choice for sports car enthusiasts who are always on the hunt for the next adrenalin rush. Our new Roadsters offers a powerful sense of freedom and adventure in an exclusive high performance environment.”

Fully automatic: the weight-optimised fabric soft top

Both Roadsters are transformed from coupés to open-top sports cars at the touch of a button and even on the go. The three-layered fabric roof with magnesium/steel/aluminium support structure opens and closes in around 11 seconds, and can do this at speeds of up to 50 km/h. Additional rollover protection is provided by an integrated aluminium cross-member with rollover bars. Three colour options for the soft top - black, red and beige – are available to complement the 11 exterior and 10 interior colours for the models.  

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

At the heart of the AMG GT C Roadster is a 4.0-litre V8 biturbo engine - 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 newton metres is available from 1900 to 5750 rpm, while a sprint from zero to 100 km/h is achieved in 3.7 seconds, and culminates in a top speed of 316 km/h.

The AMG GT Roadster has an output of 350 kW (476 hp) and 630 Nm of torque, and equally impressive acceleration response to 100 km/h in just 4.0 seconds, and a top speed of 302 km/h.

Also adapted: the dual-clutch transmission

By modifying the hardware and software, 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. 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 exceptional responses to sudden accelerator movements.

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 system

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 R

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.

Highly expressive: the athletic exterior design

From the expressive AMG Panamericana grille to the long, muscular bonnet and wide rear end, the two-seater guarantees a pure sports car experience even when stationary. The striking AMG Panamericana grille underlines the motor racing heritage: 15 chrome-plated, vertical bars echo the look of the current Mercedes‑AMG GT3 customer sports racing car.

Greater rigidity and low weight: intelligent material mix

Mercedes-AMG uses an intelligent material mix for the body structure of the AMG GT and GT C Roadster. Various aluminium alloys are used for the chassis and body, and magnesium for the front deck. This extremely light element at the front reduces the inertia ahead of the front axle, thus improving agility.

The boot lid is particularly light, thanks to an innovative composite material. The load-bearing structure is of SMC (Sheet Moulding Compound) with carbon fibres. These high-tech plastics excel with their light weight, great strength and first-class surface condition. These innovative materials were developed by the Mercedes‑Benz TEC factory in Sindelfingen, and brought to production maturity together with the AMG specialists in Affalterbach. This material combination is used for the first time in the new AMG Roadsters.

Even more agility: active rear axle steering from the AMG GT R

As standard the new Mercedes-AMG GT C Roadster responds even more sensitively thanks to the active rear axle steering that had its debut in the Mercedes-AMG GT R. The system offers an ideal combination of agility and stability ‑ handling characteristics that are normally in direct conflict.

With the rear wheels turning in the opposite direction to the front wheels up to a speed of 100 km/h, the Mercedes-AMG GT C Roadster turns into corners with significantly higher agility, to deliver even more driving pleasure with less steering input required.

Once the speed of the AMG GT C Roadster exceeds 100 km/h, the system turns the rear wheels in the same direction as the front wheels. This noticeably improves handling stability. At the same time, the lateral force on the rear wheels builds up considerably faster when changing direction, which makes the response to steering inputs quicker.

On board as standard: the rear-axle locking differential

As standard, the AMG GT C Roadster is equipped with an electronically controlled locking differential at the rear axle (Mercedes-AMG GT Roadster: mechanical locking differential), which is integrated into the compact transmission housing. Its sensitive and rapid control elevates the physical handling limits to a new level. It not only further improves the grip of the driven wheels, but also increases the cornering speeds at the limit.

High quality and exclusivity: the interior

The interior design echoes the design lines of the exterior. The dashboard places strong emphasis on width, creating the impression of a powerful wing. The high beltlines, concave door panels, dynamically rising centre console and low seat position perfectly integrate the driver with the cockpit. The new, light-coloured interior in macchiato beige Exclusive nappa STYLE leather is available for the first time, lending the open-top sports car even more individuality and exclusivity.

Standard features include an Exclusive nappa leather interior for the GCC, and the AMG performance steering wheel in nappa leather.

More lateral support and comfort: AMG performance seats

The optionally available AMG performance seats provide even more lateral support with more heavily contoured backrest and seat cushion side bolsters. For the first time the AMG performance seat is also optionally available with the AIRSCARF neck-level heating system, which makes open-air driving enjoyable even in low outside temperatures.

Hot summer days are also factored into the design, with comfort ensured by seat climate control, which is also available exclusively for the AMG performance seat for the first time. The intensity of the climatisation can also be set in three stages.

Impressive sound in the interior: External Coupled Subwoofer

The Burmester® surround sound system and the Burmester® high-end surround sound system ensure a superior musical experience in the AMG GT Roadster. Both systems benefit from the innovative External Coupled Subwoofer (ECS). This new bass sound reproduction system with an extremely low bass range turns the open two-seater into a mobile concert stage. Instead of a subwoofer box of limited dimensions, ECS uses the entire interior as a bass box.
