If you can’t wait for Mercedes-AMG to introduce the Black Series version of the GT R, you can always turn to certain tuning companies that will take care good care of it.
When it leaves the factory, the GT R has a twin-turbo 4.0-liter V8 that pumps out a healthy 585 PS (577 HP / 430 kW) and 700 Nm (516 lb-ft) of torque.
Take it to Renntech, however, and they will bump the output up to 825 PS (813 HP / 606 kW) and 850 Nm (627 lb-ft). The extra muscle comes after the tuner upgraded the ECU, installed a larger turbo and air filter, and fiddled with the blow-off valves and other parts.
In order to cope with all of that power, the Mercedes-AMG GT R has had its dual-clutch seven-speed automatic gearbox upgraded. We don’t know how fast Renntech’s GT R is, but the stock model needs 3.6 seconds for the 0-100 km/h (0-62 mph) sprint and maxes out at 318 km/h (198 mph).
There’s a lesser version available as well, which provides just a minor power boost, to 612 PS (603 HP / 450 kW) and 730 Nm (538 lb-ft).
Renntech also took care of the exterior by adding front bumper canards, side rocker panels, a larger two-stage rear wing and bigger diffuser at the rear. These are complemented by a new set of wheels, measuring 10×19-inch at the front and 12×20-inch at the rear and wrapped in 285/30 and 335/25 Michelin Pilot Sport Cup 2 ZP semi-slick tires respectively.
