• 2020 Mercedes-AMG G63 by PerformMaster

This Mercedes-AMG G63 receives a lot of carbon fiber treatment and a healthy power boost

LISTEN 04:31

The Mercedes-AMG G63 is turning out to be quite popular with the aftermarket tuners. We’ve seen builds from companies like Carlex Design, Wald International, Brabus, Mansory, and many others in the past.

This time, another company has laid its hands on the luxurious, boxy SUV. Germany-based PerformMaster has given the G63 a twist that includes a few cosmetic changes and a power bump that pushes it over 800 horses. Is this enough to set it apart from other customized builds?

What’s Different On The Outside?

PerformMaster has equipped the G63 with a wide body kit and a generous dose of carbon fiber all around the body. With the kit, the SUV is now 3.9 inches wider than the standard G63.

The track of the SUV is also widened by the same number. Up front, the stock bumper makes way for a wider carbon fiber bumper that gels well with the body shade. It also comes with a front splitter here. Perform Master has installed LED daytime running lights to the headlights. To wrap up the face, there’s a carbon fiber hood attachment and a front spoiler on the roof that make this G63 look one-of-a-kind.

The wide carbon fiber bumper design continues to the side profile in the form of carbon wheel arches. The tuner has equipped running boards with LED lighting here that turns on when the door is opened. Surprisingly, there’s no unique wheel design here. The black wheels with red rims look fine, but something less contrasting would look even better. The same carbon fiber treatment continues at the back as well. A wider bumper is placed at the rear with vents to dissipate the hot air. Finally, there’s a carbon fiber rear spoiler to end the list of changes that PerformMaster has made to the Mercedes-AMG G63.

This Is Faster And More Powerful Than The Standard G63

The standard Mercedes-AMG G63 comes packed with a 4.0-liter, V-8 Biturbo engine that makes 585 horses and 627 pound-feet of torque. Power is sent to the wheels via a nine-speed automatic gearbox. It features a central differential lock along with a front and rear diff lock, and a low range as well. It takes 4.5 seconds to hit the 62 mph mark.

PerformMaster has upped the ante a bit. The same engine is upgraded and now makes 805 ponies and 752 pound-feet of torque.

This comes courtesy of the company’s PEC tuning module with Bosch wiring. With the power bump, this SUV now takes just 3.9 seconds to sprint to 62 mph, 0.6 seconds faster than the stock G63.

PerformMaster Has Thrown In A Freebie

It isn’t exactly a freebie, but more like part of the package. PerformMaster has said that the first eight people to order the full tuning package will get a chance to take part in an event organized by the tuner. The chosen ones will drive a lap around a racetrack in the Mercedes-AMG GT4 with Bernd Mayländer, Formula 1 safety car driver, as the co-pilot.

Final Thoughts

PerformMaster hasn’t revealed the price yet for this build, but you can expect it to be north of $200,000, including the price of the donor vehicle, which itself starts from $156,450. The company didn’t go overboard with the cosmetic changes and that’s a good thing. A lot of changes generally draw polarizing opinions, but this build will please all and offend none. There are no changes made to the cabin, although a few exclusive touches would’ve been appreciated.

The highlight is the power boost and the faster 0-62 mph time. Also, the company is offering a full warranty on the engine, turbos, transmission, and the differential. All-in-all, the PerformMaster G63 is a pretty good package and you should shortlist it if you’re looking to buy a customized Mercedes-AMG G63.
