Performmaster injects some serious horsepower into Mercedes-AMG G63

Performmaster, a dedicated Mercedes-AMG tuner based in Germany, has released a tuning plan for the latest Mercedes-AMG G63 (W463A) that helps it beat even the AMG GT!

The stock V8 with its 585 hp (436 kW) and 850 Nm (627 lb-ft) of torque gets new, in-house designed turbochargers, increased boost pressure, and various structural reinforcements, as well as some ECU tuning. Once complete, the upgrade lifts the output to the stellar 805 hp (600 kW) and 1,020 Nm (752 lb-ft) of torque.

If you still have any doubt remaining about the efficiency of this mod, consider that the SUV now sprints 0-100 km/h (0-62 mph) in 3.9 seconds. Not bad at all for a vehicle that weighs in at two and a half metric tons (5,500+ lbs)! To put things into perspective, the much lighter Mercedes-AMG GT – a purebred sports car – accomplishes the same in four seconds at best.

The only downside is that you have to pay separately for the certificates and the warranty, if you want either.
