Ferrari 365 GTB/4 Daytona Competizione


The “Competizione” versions of the 365 GTB/4 “Daytona” model were developed from the standard road cars. There were three series of five client competition examples built at the factory's "Assistenza Clienti" department in Modena, along with an earlier one-off all aluminium bodied car for Luigi Chinetti's North American Racing Team. The first series of five competition examples, built in 1971, had all aluminium bodies. They featured slightly flared wheel arches with wider wheels, aerodynamic "fences" on the front wings, a small chin spoiler, and a lack of quarter bumpers, as the main identifying features. The second series, produced in early 1972, had steel bodies with the aluminium bonnet, boot lid, and doors of the road cars, but with much increased flares to the wheel arches, to accommodate even wider wheels and tyres. The third series, produced in early 1973, were visually very similar to the series II cars, but had steel doors, with only the bonnet and boot lid in aluminium. They received carefully built and balanced engines to racing standards, and some performance details were enhanced by the homologation of special parts over the period of production.

These competition examples proved to be very successful in the GT category, not only due to their power, but also reliability in endurance events. At the Le Mans 24 Hour Race in 1972 they filled the top five positions in their class, repeating the class wins there in 1973 and 1974. As late as 1979, they were still performing credibly with a second overall in the Daytona 24 Hour Race, an amazing result for a car that had been out of production for six years. The November 1974 issue of the American magazine "Road & Track"  featured a track test of a competition version, recording the following times, a 0-60 mph time of 5.8 seconds, a 0-100 mph time of 12.6 seconds, a standing start quarter mile time of 14.5 seconds at a terminal speed of 107.5 mph, and a top speed of 186 mph. Not vastly different to the figures for the standard road version, but a vast difference in lap times would come about through the stiffer suspension, wider wheels,  and racing tyres of the competition model. It also serves to show how good the performance of the standard car was, and how little straight line performance gain the homologated parts gave.

Apart from the “factory” cars, there were 8 unofficial but recognised converted cars, mainly for the North American Racing Team, but one was prepared by Garage Francorchamps in Belgium, and a couple for private entrants in the USA. It really was the last of a generation of competition cars that could also be used on the road, and with only sixteen official models plus the eight unofficial variants, it is even rarer than the legendary 250 GTO.
