GAD-Motors installed an uprated V8 twin-turbo M157 engine in a C63 AMG Black Series with 4MATIC.

While the standard C63 AMG Black Series has a 517 HP (380 kW) naturally-aspirated V8 6.3-liter M156 engine, this particular example received an upgraded twin-turbo V8 M157 motor which can rev over 7,000 rpm. The engine transplant has increased the coupe's output to an impressive 850 HP (625 kW) and 1,350 Nm (996 lb-ft) of torque.

Power is transferred to all four wheels via a modified 4MATIC system with a customized MCT gearbox that can handle up to 1,500 Nm (1,106 lb-ft) of torque. It will do 0-62 mph (0-100 km/h) in 3.1 seconds which makes it 1.1s quicker than the stock model. GAD's highly-tuned C63 AMG Black Series will sprint to 124 mph (200 km/h) in 8.8 seconds and needs 23.5s to reach 186 mph (300 km/h) from a standstill.

The vehicle has also received a bespoke adjustable suspension from KW while stopping power comes from carbon ceramic brakes which will stop the car from 100 km/h in 33 meters and from 200 km/h in 132 meters.

The entire upgrade kit (without the car) is available for 180,250 EUR.
