Mercedes-AMG GT S gets Piecha makeover

Published: 02 September 2016

► German tuner Piecha tweaks GT S
► New AMG GT-RSR packs 604bhp
► Monstrous 620lb ft and 205mph top speed

German tuning house Piecha, seemingly convinced that the Mercedes-AMG GT S isn’t enough of a hooligan already, has unveiled its new 604bhp take on the super-coupe. 

The AMG GT-RSR, described as ‘a diamond’s sporty high-tech sibling’, features a host of cosmetic, aerodynamic and performance upgrades.

The 4.0-litre twin-turbo remains, but Piecha has fettled it to bring power up to 604bhp (that’s 100bhp more than the AMG GT S). Torque’s up, too, from a mere 479lb ft to a tyre-troubling 620lb ft. It’s got the performance to go with those beefed-up looks, then...

0-62mph is dispatched in 3.7 seconds, while the 205mph top speed is reached ‘in a jiffy’, according to boss Marcus Piecha. Only marginal improvements compared to the regular GT S, admittedly, but we’re in the land of diminishing returns. In any instance, it sounds like a serious bit of kit.

What else has been changed?

On the outside, carbonfibre front aprons, side skirts and a carbonfibre rear diffuser hunker the car down at speed and add some visual aggression (as if it needed it), while the rear spoiler adds to the drama. Interestingly, the standard retractable spoiler of the cooking AMG GT remains – popping up and down underneath the RSR’s fixed item.

There’s extra bark to go with the bite, too – the exhaust system has been upgraded with quad double-wall 90mm tailpipes, moving away from the trapezoid shape of the standard car.

Making vague attempts at keeping the thing in check are Yokohama tyres unique to the GT-RSR – 275/35 ZR19s at the front and 305/30 ZR20s at the back. They’re geared towards hanging together at that 205mph top speed, should you find yourself on a German autobahn.

What’s not to like?

The LED lighting in the side skirts. The five underfloor LED lamps make the RSR look a little like something straight out of Need for Speed. Whether that’s a good thing or not, ultimately, is up to you...
