The extensive engine mods include the increase of the V8's displacement from 4.8- to 5.0-liters and the fitment of fortified forged pistons, special connecting rods, racing turbochargers along with a new air intercooler plus a remapping of the ECU. The result is an impressive output of 750HP at 6,400 rpm and a maximum torque of 1,050Nm or 774-lbs/ft at 3200 rpm. The Tornado 750 GTS accelerates from 0 to 100km/h (62mph) in 4.3 seconds and has a top speed in excess of 300 km/h or 187mph.
To put all that power on the road in a politically correct manner, Gemballa's engineers outfitted the Cayenne with a sports suspension that includes an adjustable coilover kit that allows the lowering of the car by up to 70mm. The Tornado 750 GTS rides on a set of extra light 22-inch alloy wheels shod in 335/25 Z22 high performance tires while stopping power is provided by a new braking system with 6-piston brake callipers and 420mm discs at the front axle and 4-piston brake callipers with 380mm discs at the rear axle.
On the outside, Gemballa's team turned the Cayenne into a vehicle that could easily have had a role in the movie Death Race. Aerodynamic accessories aside, one of the highlights is the bonnet which has been 'fused' with the front wings and now opens as a whole.
Inside, Gemballa opted for a four-seat layout while the cabin has been upgraded with new materials and a redesigned center console hosting the lifted gearbox and the Data Control System.
The German tuning house said that the Tornado 750 GTS will be built in a limited number of 50 units with prices set at €400,000 or about $520,000 US.
