Ferrari F50 GT

The car was co-developed with Dallara and Michelotto.

Following the motorsport theme of the Ferrari F40 LM, Ferrari developed the F50 GT, a prototype based on the F50 that was built to compete in GT1-class racing. The car had a fixed roof, a large rear wing, new front spoiler and many other adjustments. The 4.7 litre V12 engine was tuned to generate around 750 bhp at 10,500 rpm and 520 N.m of torque at 7,500 rpm. A test held in 1996 proved the car to be quicker even than the 333 SP, but this went unnoticed as Ferrari cancelled the F50 GT project because it was unhappy with FIA allowing homologation special cars such as the Porsche 911 GT1 in the series. Ferrari instead focused on Formula One after the BPR Global GT Series folded. The company sold off the three complete chassis out of the six planned chassis that were built–the test car 001, 002 and 003. Chassis 002 and 003 had bodies fitted before being sold. The remaining three tubs were reportedly destroyed.
