Despite only 30 FXX supercars being produced in total (not including the even more extreme Evolution models), German tuner Edo Competition has managed to get its hands on one of the ultra-rare cars and has modified it to be street legal. For anyone unfamiliar with the FXX, the car is a development test-bed for new technologies that will eventually filter across to Ferrari’s road cars.

Owners of the car are given the chance to drive it regularly on Ferrari’s Fiorano test track in Italy, where the carmaker’s own engineers compile useful data from the track sessions to help develop future models.

For this reason, the FXX was never intended to be driven on public roads. That was never going to stop Edo Competition’s founder Edo Karabegovic, who saw modifying the FXX as a challenge.

Straight out of the box, the FXX features a 800hp (598kW) 6.3L V12 engine, 19in forged alloy wheels shod with racing slicks, carbon-ceramic brakes and a gearbox that manages to shift gears in less than 100ms. The car is also so low that it is almost impossible to drive it on public roads.

To meet Germany’s TÜV regulations, the only changes needed were the addition of new brake pads, production car tires, an exhaust valve and a more restrictive catalytic converter. Surprisingly, Edo were able to squeeze an additional 80hp (59kW) from the high-strung engine with only some minor ECU mods.

For now the car will remain the property of Edo but if one of the other 29 owners, including Michael Schumacher, wants to make their cars road legal they now know who to call.
