After improving the performance of the Mercedes-AMG GT Black Series last year, German tuner OPUS Automotive is now back with an improved version of the GT R called the R777 GT R.

The car is equipped with improved suspension that provides better stability in all driving situations, rear spoiler like the one used by AMG GT4 race cars which increases downforce, carbon front vents (which makes the front of the car look even more aggressive), improved brake cooling system, brake calipers high performance, and 19 inch and 20 inch wheels wrapped in Michelin Cup2 R tires.

The R777 GT is powered by a 4.0-liter twin-turbocharged V8 engine with 777 hp (571 kW) and 625 lb-ft (847 Nm) of torque. This is a significant increase in power compared to the base model, which has 577 hp (424 kW) and 516 lb-ft (700 Nm) of torque. This has been achieved through the installation of improved turbochargers, sports catalysts, improved intercoolers and new engine and transmission software. Opus pointed out that torque is limited due to the durability of the drive.

If 777 hp is not enough for someone, the tuner offers a special equipment kit that increases power to more than 900 hp.
