Ferrari is reportedly working on an open-top version of their hypercar and a hardcore model - the LaFerrari FXX track. Both models could launch in 2015 in very limited numbers. 50 for the LaFerrari Spider and 30 for the LaFerrari FXX.

It will cost twice the price of the coupe, according to insiders.

The FXX version will be a track only car and for road use and will be looked after by Ferrari and driven by owners at its private circuit events.

The FXX will be even more powerful than the standard car, with the V12 and the electric motor rumored to produce a combined 1,050 hp, 100 hp more than the street-legal model.

The standard car sprints from 0 to 100 km/h in less than 3 seconds and reaches a top speed of more than 217 mph (349 km/h) so expect more from the FXX.
