This Mercedes-AMG GT 63 S runs the standard sprint in 3 seconds flat

Even in its stock guise, the Mercedes-AMG GT 63 S packs formidable performance courtesy of its 4.0-liter twin-turbo V8 rated at 630 hp (470 kW) and 900 Nm (664 lb×ft) of torque. Despite this, the guys over at Performmaster believe it is capable of more than that with the help of a bit of chip tuning.

The PEC Tuning Module plugs directly into the ECU and raises the output to 730 hp (544 kW) and 1,030 Nm (760 lb×ft) of torque. Once upgraded, the supercar sprints from zero to 100 km/h (62 mph) in three seconds flat and reaches 200 km/h (124 mph) in mere 9.9 s. Keep in mind that all tests took place on a race circuit, meaning that a dedicated drag strip could improve these results even further.

Performmaster also offers an aero kit for the model, including a front splitter, a rear wing, and a rear diffuser. You can also lower the suspension using height-adjustable springs.

The tuner will only be releasing 31 such Mercedes-AMG GT 63 S upgrade kits to celebrate its 31st birthday.
