Around a year ago, Performmaster GmbH
produced a limited batch of Mercedes-AMG GT63 S customs. All 31
units were sold, but now, another batch is coming up with even higher specs.
In its stock guise, the luxury saloon
packs 630 hp and 900 Nm of torque. The Stage 1 kit from
last year resorts to chip tuning to get 730 hp and 1,030 Nm of torque out of the car’s four-liter V8. The newly announced Stage 2
introduces turbocharger modifications and results in 810 hp along with
1,070 Nm of maximum torque.
Once tuned, the saloon only needs 2.8
seconds to get from standstill to 100 km/h, whereas the unmodded car
needs 3.2 seconds. It also maxes out at 340 km/h instead of the
manufacturer-guaranteed 315 km/h.
Performmaster has not revealed the pricing
and availability information yet.
