THe tuner Sportec->ke630 dropped this one on us in Geneva. It's the SPR1 M, an extremely modified version of the 997 Porsche Turbo. The M will be an extremely exclusive model with only 10 vehicles planned for production. Power has been increased to 858 HP and weight has been drastically reduced thanks to a plethora of carbon fiber. Expect the Porsche->ke1 to go from 0-60 MPH (0-100 km/hr) in under 3 seconds.

Specs and more after the jump.
