The new Mercedes-AMG GT S Roadster

2019 Mercedes-AMG GT S Roadster

New open-air member of the AMG GT family

Later this year, Mercedes-AMG is extending its sports car portfolio with an attractive open-air model: the new AMG GT S Roadster. With this latest addition, the AMG GT family now has a dozen members: four two-door Coupes, three Roadsters, two customer sports racing cars and three four-door Coupes. The basis for the high Driving Performance of the new AMG GT S Roadster is the combination of 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 is rendered even more dynamic by 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 open- top two-seaters.

Muscular power unit for a top speed of over 190 mph
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.

With adaptive adjustable damping as standard
The AMG GT S Roadster is equipped with the 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.

Choice of driving experience from comfortable to very sporty
The driver is able to set the AMG GT S Roadster to his/her individual requirements using the AMG DYNAMIC SELECT controller. 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.

In all modes, key parameters such as the response of the engine and transmission, the accelerator characteristics, AMG RIDE CONTROL sports suspension, the steering, the 3-stage ESP® and the position of the AMG Performance exhaust flaps are modified.

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. The suspension set-ups can also be selected specifically as needed.

Standard equipment: Electronically controlled rear differential
As standard, the AMG GT S Roadster is equipped with an electronically controlled locking differential at the rear axle, which is integrated into the compact transmission housing. Its precision and fast control raises the limit of vehicle dynamics to a new level. It not only further improves the traction of the drive wheels, but also increases the cornering speed capability. The result is that the driver is able to accelerate out of corners earlier and with more power thanks to the improved traction. The vehicle remains more stable when braking from high speed, while the limited-slip differential also improves traction.

The greatest benefit of the electronic rear-axle limited-slip differential is the even more precision and proactive control, which pushes the performance threshold higher, making it even easier to drive at the vehicle’s limits. To deliver optimum cooling, the housing of the limited-slip differential has additional cooling fins.

Large dimensions: the AMG high-performance composite braking system
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 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.

Intelligent lightweight construction with high proportion of aluminum
For the body of the GT S, Mercedes-AMG has opted for an intelligent and particularly lightweight mix of materials with a high proportion of aluminum. The spaceframe and exterior parts are of aluminum, and the trunk lid too is particularly light in weight thanks to an innovative composite material. The load-bearing structure is made of SMC (Sheet Molding Compound). These high- tech composites excel with their lightweight design, high strength and outstanding surface quality. The innovative materials were developed by the Mercedes-Benz TEC factory in Sindelfingen, and brought to production  maturity together with the AMG specialists in Affalterbach. The extremely lightweight front deck made of magnesium reduces the inertia ahead of the   front axle, improving the agility of the Roadster.

Weight-optimized: the fabric soft top
The three-layered fabric soft top is supported by a magnesium/steel/aluminum structure of low weight, which helps to keep the vehicle’s center of gravity low. Additional roll-over protection is provided by an integrated aluminum cross- member, while the inserted acoustic mat improves noise comfort.

Authentic sports car experience embodying sensual purity
From the expressive AMG radiator grille to the long hood and the muscular tail end, the two-seater guarantees a pure sports car experience even when stationary. The flat front section and forward-sloping radiator grille make the Roadster appear to hug the road. At the same time this shape lowers the vehicle’s back-pressure point, enhancing the flow of cooling air and the car’s aerodynamic performance.

The front bumper has a jet wing design that emphasizes the car’s width, making it sit flatter on the road. The large outer air inlets guarantee the supply of cooling air to the engine. The LED High Performance headlamps offer more safety at night and an unmistakably sporty and distinctive look. Thanks to LED technology, they illuminate the road more effectively than conventional headlamps – with lower energy consumption.

Viewed from the side, the arched roof line (when the soft top is closed) and the frameless doors are eye-catching features. The surfaces and lines of the side   wall flow into the tail end with a dramatic tapered effect. The long hood with its pronounced powerdomes, the greenhouse which has been moved far back, the large wheels and broad tail end also contribute to the distinctive looks. As standard the AMG GT S Roadster is equipped with mixed tires on 19-inch rims at the front and 20-inch rims at the rear.

The high-gloss chrome features in the standard-equipped AMG Chrome package include the front splitter, the fin on the air inlet grilles in the front bumper, the fins in the fenders and the trim strip in the diffuser.

AIRPANEL active air management system
The active air regulation system AIRPANEL included as standard is a particular technical highlight. Vertical louvers at the bottom of the front bumper are opened and closed electronically by means of an electric motor in around one second to guarantee the required amount of cooling. Constantly achieving the ideal position calls for highly intelligent and fast control.

During normal driving with no increased cooling demand, the louvers are closed for reduced drag and the air is directed at the underbody. This improves the aerodynamic efficiency of the vehicles. Only when certain components reach predefined temperatures and the air demand is particularly high do the louvers open to allow the maximum cooling air flow to the heat exchangers.

As another active aerodynamic component, the Roadster features an extendable rear spoiler. This reduces lift at the rear axle at higher speeds. With its broad shoulders and expressive taillamp graphics, the rear end enhances the emotional overall appearance.

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

The performance seats are upholstered in black MB-Tex man-made leather/DINAMICA microfiber as standard. Numerous other materials and colors are also optionally available:

  • Nappa leather in Black
