2015 Porsche Panamera Turbo GTP 720 by Gemballa

German tuner Gemballa has unveiled a 710-horsepower (720 PS) Porsche Panamera that is able to hit a top speed of 211 mph (340 km/h).

During independent tests on a closed-off airport in Germany, the Porsche Panamera Turbo GTP 720 achieved a new acceleration record for road-legal cars in its weight category and a new lap record at the Sachsenring circuit for Panamera-based cars, which now stands at 1:37.08.

The four-door saloon can accelerate to 60 mph in just 3.1 seconds, a whole second faster than a standard version.

0-186 mph: 26.4 s - 60 s

"This exceptional performance is not only due to the car's horse power but also to its torque, raised by 188 lb (255 Nm) and available over a wide range of revs," says Gemballa CEO Andreas Schwarz.
