After a 20 year absence from sports prototype racing, Ferrari revealed the F333 SP as part of their successful return. Built initially to run IMSA’s Exxon World Sports Car Championship in 1994, many called it an F1 car with two seats and full bodywork. Intended for private teams, the F333 was also quite successful—it won 12 Hours of Sebring, 24 Hours of Daytona and many championships in the period between 1998 to 2001.

Derek Bell, who has driven Ferrari’s sports prototypes from both eras says the F333 “drives like a wide bodied F1 car and is totally complete, flawless and homogeneous.”⁴

The F333 was constructed using techniques from Ferrari’s own F92 Formula 1 car, but was designed and manufactured partially at the facilities of Dallara in Parma and later with Michelotto Automobili in Padova. Chief Designer Mauro Rioli and aerodynamicists Dialma Zinelli and Giorgio Camaschella designed the car as a widened F1 with a fully-enclosed, two-seat body.⁵ WSC regulations meant that the car had to be an open-top, flat-bottomed design with no ground-effect venturis and be powered by a 4.0-liter, unblown engine sourced from a production car.

Fortunately, Ferrari had the F50, also known as project F130, coming down the pipeline so the engine was sourced from it. This unit was inspired by the 3.5-liter F1 engine and reduced from 4.7 to 4.0-liters which gave a single cylinder displacement of 333 cc. 650 bhp was possible when the car wasn’t running with restrictors that were imposed on the teams in later years. Unique to the design was a 5-valve cylinder head which could freely rev above 10,000 rpm and created a distinctive sound described by the teams as the “l’arrabiata” or enraged one.⁴

Chassis construction of the F333 is made from carbon-fiber composite and aluminum honeycomb covered by a carbon-fiber/nomex body. The panels are all quickly removable to reveal the fully-stressed V12 engine and sequential-manual gearbox which are an integral part of the chassis. The driver is quite well protected by a substantial roll hoop and additional bracing. Inside, the cockpit purposely sparse except for a few essentials such as toggles, fuses and the digital dashboard.

Racing

Since this was the first prototype from Ferrari since the 312 P of 1971, it won many prestigious events outright that hadn’t had a Ferrari victory in over 20 years.

The first F333 appeared at to prospective owners before the 1994 season by MOMO owner and sometimes driver Giampiero Moretti. During that season four cars were sent to America to compete in the IMSA GT Championship and they debuted mid-season in the Atlanta Sprint at Road Atlanta to win a resounding victory first time out. They won four races that year, but lost the overall Championship to the Oldsmobile Cutlass Supremes by four points.

In 1995, the design was updated to a new longer nose and each car had different aerodynamic details depending on the downforce required. Scandia Motorsports put their car to good use and won the 1995 12 Hours of Sebring outright. Another car would repeat this feat in 1997 and 1998, but the overall victory at Le Mans eluded the Ferrari. Another historic victory came at the 1998 24 Hours of Daytona when the F333 SP’s 1-2-3 victory was reminiscent of Ferrari’s own 1-2-3 in 1967.

Michelotto’s Series II

Driver Didier Theys said the F333’s “potential, if it were a Factory entry, would be far greater since none of the teams had the means to truly develop it extensively.” He talked about the development: “For 1996 at Momo we developed closed flanks bodywork. This and other versions were studied by Michelotto before they produced their 1998 body. For Le Mans and the European ISRS series the rules have allowed a six speed gearbox as well as one inch bigger wheels.”⁴

Kevin Doran, who managed the Momo team with Didier said “There has been very little development to the car in all these years because it has been very good from the beginning. The new nose developed for 1995 was, I think, primarily for aesthetics!” He also says the only major revision to the car was the 1998 engine which was much more durable thanks to its smaller valves and modified air filter.⁴

From car number 017 forward, the 1998 cars received the small-valve engine, a strengthened chassis and four-pages of numerous detail changes engineered by Ferrari themselves. These won Sebring and Daytona outright with a class victory at Le Mans. With even more updates, the F333 was successfully raced up to 2001 and won the FIA Sportscar Championship and IMSA GT Championship several times. In 2000, the Doran racing team fitted Judd GV4 V10 in an attempt to keep the old chassis competitive.

In total around 40 cars were manufactured in two series. The first 14 were constructed by Dallara while the remaining cars came from Michelotto. Ferrari priced the car at $900,000 USD which included two extra engines and a cache of spare parts.¹

Our feature example is chassis 028 which was sold new to Benny Caiola 1999. Manufactured in 1999 by Michelotto, it was only used sparingly as a track-day toy and was preserved in outstanding and original condition. It will be offered by Gooding & Company at their upcoming 2011 Scottsdale Auction.
