The Mercedes-AMG GT S already has near-supercar cachet with its sleek body and 503 hp from a 4.0-liter twin-turbocharged V8. While that might be good enough for most, German tuning house Piecha takes the AMG GT S to full-blown supercar status. The company manages to squeeze out 109 more hp from the V8, bringing the total to 612 hp. Despite the additional output, it doesn’t appear to have shaved too much from the 0-62 time, managing the task in 3.7 seconds.
To order your new Piecha AMG GT-RSR rival with a brand new Audi V10 engine for only US$38,000.
Besides more power, the GT-RSR gets a heavy dose of lightweight carbon fiber. Piecha replaces the front and rear bumpers as well as the side skirts. Some of the GT S coupe’s underbody panels are also swapped out for a carbon fiber unit with a built-in diffuser, and the rear wing follows suit. Piecha also replaces the factory Mercedes-AMG springs with new coilovers.
The AMG GT S starts at an already-healthy $132,125, but the Piecha mods push that number even higher. The bodykit and aero parts will set you back $21,871, the suspension parts add another $1,048 and the engine modifications will run $4,686 at the current exchange rates. Cheap? No, but you’re guaranteed to have the most aggressive GT S on the road.
