Gemballa started his business in 1981 in Leonberg in Germany. Today the brand continues its activity after the death of Uwe Gemballa, which took place in 2010. The preparation mainly concerns Porsche cars, with a style that is often anything but discreet. The engine transformations are very intense: the 911 Turbo, for example, sees the power go from 540 to 818 horsepower, taking the name GTR 8XX Evo-R, with a maximum speed of 370 km / h.
