Mercedes-AMG GT Now has 2 Topless Variants – the GT Roadster and 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 557 hp and peak torque of 680 Nm, 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.

The 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.

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.

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. 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.

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.

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.

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.

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.

The already rigid bodyshell structure has been specifically reinforced further to take account of the car’s design as a roadster: side skirts with greater wall thicknesses and more chambers make the structure more rigid, for example. The dashboard support is braced against the windscreen surround by additional struts, and a strut tower brace between the soft top and the tank reinforces the rear axle. A cross-member behind the seats supports the fixed roll-over protection system.

 

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.

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.

Up to a speed of 100 km/h, the rear wheels are turned in the opposite direction to the front wheels, the Mercedes-AMG GT C Roadster turns into corners with significantly higher agility as a result, delivering even more driving pleasure and requiring less steering input. In day-to-day driving the driver also benefits from a reduced turning circle, for example when turning off or parking.

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. The driver also notices the high grip and stability of the Mercedes‑AMG GT C Roadster during rapid changes of direction, without the usual tendency for the rear to break out.

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.
