Modified outside and under the hood, it's the interior that appears to have received the most attention.
Set for a world premiere next week at Geneva is this Porsche Panamera Sport Turismo tuned by German-based Techart. Techart calls it the GrandGT Supreme styling package, specifically for the Panamera Sport Turismo. Styling wise, it dramatically enhances the car’s presence, starting with a set of 22-inch wheels with the entire car painted in gorgeous racing green. Also added is a Techart sport exhaust system with titanium and carbon fiber tailpipes. But it’s the interior that’s received the most attention.
Techart’s in-house team of expert craftsman developed an un-embossed Nappa leather with a smooth and natural texture that covers the entire interior, including the footwell and door panels. The leather has been vegetable-tanned so that it’s free of chromium. Also take note, in the included photos, of some of the finer details, such as the handmade multi-color stitching and customized Techart sport steering wheel. Under the hood lies the Panamera Turbo’s 4.0-liter bi-turbo V8 whose output has been increased from 550 hp to 640 hp. This engine upgrade also reduces 0-62 mph time to just 3.4 seconds and 0-124 mph in 8.3 seconds.
