RM Auctions recently listed a rare Ferrari F40 Prototype for its Monaco auction, due to take place on May 12 at the Grimaldi Forum. This particular Ferrari F40 Prototype, one of eight F40 Prototypes known to exist, has been converted into GT racing spec by Michelotto. It has spent time more recently in the garage of a Milanese collector.
The car RM Auctions offers for sale is the sixth of eight cars used by the factory for testing. It is chassis number 74047, displayed at the 1987 Frankfurt Motor Show after which, GT modifications were made. As a result, this F40 features a ride height lowered by five centimeters, 590hp, Brembo brakes, a racing uniball suspension, a quick-fill fuel system, extra NACA cooling ducts, a fire system and wider Speedline wheels.
This particular Ferrari F40 Prototype still wears ToTip racing livery, the colours it wore to secure two first and two second place podiums in the Italian Supercar GT Championship. The upgrades from Prototype to GT specification were carried out in 1987 by Michelotto with further work completed in 1993 to maintain its competitive edge.
It comes complete with Ferrari Classiche attestation. The estimate is between € 700,000 and € 900,000.
