Car of the Day - Ferrari P4/5
Ferrari throughout its history supplied cars and chassis for special “Carrozzeria” treatment. In the early days it was a “relatively” common practice. During the transition to a “modern’ manufacturer, it was not so common, not as well known and far less accessible. In fact the entire practice was really aimed towards one client. The Sultan of Brunei’s brother. Many very special Ferrari’s were build during this period, predominantly by Pininfarina on 456 and TR chassis, usually in batches of less than ten in a selection of colors.
Well publicised domestic problems stopped this lucrative income stream for Pininfarina. Individualisation of Ferraris was for a period only available by the “tuner” route. We are now though in the early stages of a revival with some notable coachbuilt cars coming out of the new “Portfolio” program.
Perhaps the highest profile and most successful design to date is this one, the Enzo based P4/5. The dream of American James Glickenhaus, it is a modern interpretation of the classic Ferrari 330 P3/4, of which Glickenhaus also owns an example. The development of the P4/5 commenced in 2005, before the instigation of the new Ferrari Portfolio Program and the success of the car undoubtably helped Ferrari come to the conclusion the market was ripe for their new service. While this was pre Portfolio, Ferrari obviously liked what Glinkenhaus and Pinifarina were doing and not only supplied technical assistance but also their blessing to use the P4/5 name.
As this was a one-off coachbuilding exercise and the engine and running gear from the Enzo were already extremely capable, nothing was changed mechanically. With regard to the complete redesign of the body though, this was not just a “make it look good” exercise, a complete full scale mock-up was built for use in the Pininfarina wind tunnel. The result of the tuning to the final design was a reduction of drag while matching the Enzo’s downforce.
Adding to the reduction in drag is a 200kg reduction in weight with the P4/5 tipping the scales at 1200kg. The P4/5 would undoubtably be one dynamic performer.
