Techart is heading to the 2018 Geneva Motor Show with at least four Porsche projects.

Headlining Techart’s lineup is the world premiere of its new Porsche Panamera Sport Turismo project, called the GrandGT Supreme. The exterior receives a new Techart GrandGT styling package, along with 22-inch Techart Formula IV wheels, a Techart sport exhaust system with titanium and carbon fiber tips, as well as a custom painted body in Racing Green.

The interior of the customized Panamera Sport Turismo gets an overhaul as well, with un-embossed Nappa leather being used. The famous tuner says the vegetable-tanned hides are free of chromium and are finished solvent-free. There’s also a custom Techart steering wheel and painted trim panels, matching the exterior body shade.

Power has been increased to 640 horsepower, while maximum torque is 664 pound-feet. As a result, the stylish Sport Turismo goes zero-to-62 mph (0-100 km/h) in 3.4 seconds.

Joining the Porsche Panamera Sport Turismo project in Techart’s booth at Geneva is a modified 911 GT3, which includes a carbon fiber sport package, the Techart GTstreet R Cabriolet based on the 911 Turbo S, and a Macan to show off the Techart range of products for the crossover.
