Ferrari’s Special Version cars push the performance of its production models to new extremes. Some, such as the 488 Pista and 812 Competizione, have earned a rightful place in the Prancing Horse’s recent pantheon. Ferrari’s ‘XX Programme’, on the other hand, offers a select group of expert client drivers extreme cars that are not homologated for the road, to drive on the very limit on the track. One such model is the FXX-K EVO. Ferrari has now drawn on these two different spheres of experience to create a Special Version that draws on the programme’s concepts to make it effectively a road-legal XX: the SF90 XX Stradale. Its performance has been raised to impressive new heights by an additional 30 cv, specific software logics and the use of radical new aero solutions, not least a fixed rear wing, the first to appear on a road-going Ferrari since the days of the F50.
