Edo Competition takes the Mercedes-AMG GT R past 650bhp

German tuner imparts chassis and engine modifications on Mercedes-AMG GT R supercoupe.

With more power and a greater track focus, German performance tuner Edo Competition has turned the wick up on the Mercedes-AMG GT R. Edo hasn't disclosed a price for the upgrade package. 

While the engine modifications aren’t extensive, they’re effective, thanks to the receptiveness of modern turbocharged engines to tuning. Edo has extracted an extra 74bhp and 59lb ft of torque from the 4.0-litre twin-turbo V8 by increasing boost pressure, the result being new peaks of 651bhp and 575lb ft – both coming on stream slightly later than the peaks of the standard car.

The Edo GT R will sail past the standard car's limited top speed of 198mph, running out of puff at 211mph. Despite the traction-limited, rear-drive layout, Edo claims to have shaved 0.3sec off the stock car’s 3.6sec 0-62mph time.

evo comment - Mercedes-AMG GT R

‘Out on the road the Mercedes-AMG GT R feels hardcore. That’s as you’d hope, but it’s a very firm car, even in Comfort mode. On the plus side that means it’s sharp as a flick knife, cutting a clean line through the corners and revelling in rapid direction changes’

To provide the Edo GT R with a bespoke aesthetic and refocus the chassis setup for more track driving it has been lowered by 25mm at the front and 20mm at the rear. While the drop in ride height won’t guarantee quicker lap times, the squatter stance lends the already aggressive-looking Mercedes-AMG GT R even more purpose.

Edo claims the ride comfort hasn’t been totally sacrificed, however, the standard car is firm already so the effect of lowering the car will likely result in an even stiffer ride: ‘The vehicle’s already sporty handling is matched by unbeatable visual impact. As the vehicle hugs the road surface, the driver experiences an exhilarating mix of dynamism, racetrack response and comfort.’
