Mercedes-AMG GT R Roadster: Closing In On 200 MPH With More Power, Active Aero

Its top speed is 197 mph, according to Mercedes

The Mercedes-AMG GT R Roadster is the fastest variant yet.

If you were to buy a brand new Mercedes-AMG GT C convertible, you wouldn’t be wanting for power. Thanks to a hand-built 4.0-liter twin-turbocharged V8, you’d get 550 horsepower and 502 lb-ft of torque in the GT C. However, as with the coupe, there’s now another, more powerful version. Enter the new Mercedes-AMG GT R Roadster.

Now with more power than before, the GT R Roadster hits 197 mph. Under the hood, that twin-turbocharged V8 produces 577 horsepower and 516 lb-ft of torque. All that power is routed through a seven-speed dual-clutch transmission, sending power to the rear wheels. That enables the Mercedes-AMG GT R Roadster to sprint to 60 in 3.6 seconds. Then there’s the wing on the back, which combines with the huge brakes and the rear diffuser to tell you this is something more hardcore than your typical convertible.

The Mercedes-AMG GT R Roadster has track focused suspension, as well as dynamic engine and transmission mounts to try and provide the best of a comfortable cruiser and a stiffer, track-focused car. On the handling front, it also has active rear-wheel steering and an electronically-controlled limited slip differential.

Active aerodynamics

Then there’s the matter of active aerodynamics. A lightweight carbon fiber element is concealed under the front of the engine in normal driving conditions. However, depending on the drive program, it can extend downward by 1.6 inches. That improves downforce, using the Venturi effect to “suck” the car down onto the road. Mercedes claims that element provides 88 pounds of downforce at 155 mph in the Mercedes-AMG GT R Roadster. The large spoiler on the back also helps aid in the dornforce task.

Inside, the Mercedes-AMG GT R Roadster greets its owners with typical Mercedes fare. You still get a 12.3-inch digital instrument cluster along with a 10.25-inch infotainment screen surrounded by black carbon fiber trim. There are AMG Performance seats finished in Nappa leather, with numbered badging on the center console. As it’s a convertible, you also get a n AirScarf heating system, as well as heated and cooled seats.

Limited availability

While the Mercedes-AMG GT R Roadster is the fastest variant yet, don’t expect it to be cheap. Partially, that’s down to the performance. That said, Mercedes is building just 750 units worldwide, so it will be an exclusive model. They haven’t announced pricing yet, but we will provide that information as it’s available.
