TechArt has unveiled the GrandGT Supreme, an extraordinary signature edition which uniquely combines sportiness and luxury. The exterior is characterised by the new TechArt GrandGT styling package for the Panamera Sport Turismo models, 22-inch TechArt Formula IV wheels, a TechArt sport exhaust system with titanium/carbon fibre tailpipes as well as a custom-painted car body in Racing Green.
The inside is once again a masterpiece of the renowned TechArt interior manufactory. Already, the choice of the leather hides for the GrandGT Supreme is unconventional.
The key challenge for TechArt’smaster craftsmen: the maintenance of softness and naturalness of the leather. And the result is overwhelming. They developed an un-embossed Nappa with a smooth and natural texture. The vegetable-tanned hides are free of chromium and are finished solvent-free.
The ultra-premium leather covers the complete interior of the Panamera Sport Turismo, including the footwells and the door panels. Combined with numerous details such as the handmade multi-colour stitchings, the customised TechArt sport steering wheel and custom-painted trims in body colour, the GrandGT Supreme has is a very high-end luxury interior.
Superior driving performance is granted by the TechArt Techtronic engine power enhancement, which boosts the Panamera Turbo’s power output to 640hp and raises the maximum torque to 900Nm. The easy-to-fit engine upgrade shrinks the gap between standstill and 100 km/h to 3.4 seconds. From this point, it takes only 8.3 seconds more to cross the 200km/h line.
