TechArt’s work on the Porsche Panamera extends all the way from the saloon’s introduction in 2009. We’ve seen the German tuner introduce different versions of its GrandGT tuning kit in the past eight years. At the 2018 Geneva Motor Show, TechArt is keeping the tradition alive with its latest and punchiest Panamera program to date. The kit is called the GrandGT Supreme, and as its name suggests, the program is a more sophisticated version of the standard GrandGT, one that features a more aggressive body kit, a more opulent interior, and enough power to justify its cutting-edge looks.

Exterior

TechArt’s exterior upgrades for the Porsche Panamera are far from subtle. That much is clear with the tuner’s standard GrandGT kit, and it’s even more prominent with the GrandGT Supreme program. Though there are some similarities between the two programs, the latter offers a more pronounced hood with a noticeable power bulge. The fenders, arches, and lower side sills are all wider to the point that they look abnormal. Together, they help enhance what is already an imposing-looking Panamera.

At the back, the tuner installed a more prominent diffuser with larger strakes than the ones found on the “standard” aftermarket version. If these upgrades aren’t enough, TechArt also installed a new set of 22-inch Formula IV wheels. And to top it all off, the tuner chose an interesting color to put the saloon’s aesthetics altogether.

We all thought that “Racing Green” only looked good on Aston Martins. Turns out, it doesn’t look too shabby on a Porsche Panamera either.

Interior

It can be argued that most of the work TechArt did with this Porsche Panamera can be found in the car’s interior. We’re not just talking about run-off-the-mill improvements, either. The tuner’s master craftsmen — yes, it has those — developed an un-embossed Nappa leather fabric that is apparently free of chromium and finished without the need for solvents. I didn’t even know that chromium and solvents were involved in the leather-making process, but that’s fine. All I know is that the good stuff is all over the interior of the Panamera, right down to the door panels and footwells.

The wooden sideboard on the dashboard and the wood trims help elevate the elegance of the cabin, while the multi-colored stitching brings out a bit of the interior’s personality.

It’s not hard to imagine what a well-appointed Porsche Panamera looks like. Porsche does a good job of doing that all by itself. But if you really want a Panamera that really looks the part of a luxury sedan on wheels, TechArt’s GrandGT Supreme kit does a good job bringing that vision to life.

Drivetrain

As exciting as the aesthetic and aerodynamic upgrades are, TechArt’s GrandGT Supreme program wouldn’t be complete without the accompanying engine upgrade. In this instance, the base Panamera Sport Turismo Turbo gets a shot of adrenaline in the form of the tuner’s gnarly TECHTRONIC tuning kit. The software program doesn’t add any turbochargers in the mix, but it is responsible for giving the saloon an extra 90 horsepower and 100 pound-feet of torque.

The result is a car that now boasts 640 horsepower and 664 pound-feet of torque, enough power to properly it from a standstill position to going 62 mph in just 3.4 seconds. TechArt didn’t say what kind of top speed the Panamera GrandGT Supreme is capable of, but if the saloon’s speed limiter was removed, we can’t imagine it doing anything less than 200 mph.

Regardless of the numbers, the GrandGT Supreme kit isn’t a novelty tuning program. It’s meant for Porsche Panamera Sport Turismo Turbo models that have no issues standing out, both on the streets, and on the race tracks.

Conclusion

When it comes to tuning programs for the Porsche Panamera, there aren't a lot of tuners that are capable of maximizing the luxury sedan's aftermarket potential. It's a good thing that TechArt happens to be one of the few aftermarket companies that can do that kind of work. It has an eight-year history of building programs for the Panamera, and it looks like that form hasn't waned since. There's a lot about the GrandGT Supreme that appeals to us. At the end of the day, that's what these programs are all about, right?
