It may look quite innocent, but this creation of Swiss tuner Sportec is a performance monster. This is the SPR1R, a faster, lighter, improved version of last year’s SPR1. Based on the Porsche 911 Turbo, Sportec has managed to squeeze out 846 hp and 870 Nm from the bi-turbo 3.6-litre flat-six engine. Weighing just 1,295 kg, the SPR1R does the benchmark century sprint in 3.0 seconds flat, on to an outrageous top speed of over 380 km/h.

Managing that excess of power will be the addition of titanium connecting rods, a flat carbon fibre under floor, active suspension and F1 style ceramic brake discs, composite (carbon/kevlar) body panels, forged alloy wheels, an integrated safety cage and four wheel drive.

Also on offer is a driver adjustable traction control system which is managed by a touch screen display unit that also logs data, lap times and allows customers to monitor engine data.
