The sport’s flexibility initially attracted manufacturers, but it’s also what made it dangerous. Core Group B rules required two seats, a minimum weight calculated by engine and tire displacement, and a roof, but outside of these regulations, manufacturers could essentially do what they pleased. FISA, now FIA, also loosened homologation rules to attract more manufacturers to the sport, only requiring 200 road-going variants of a Group B entry. In comparison, from 1982 to 1992, Group A stipulated that automakers must produce 5,000 examples of a specific model. GettyGroup B’s flexibility led to every other rally witnessing new evo models continually pushing performance limits. Ferrari had started limited Group 4 rallying experiments in 1978 with 308 GTBs. The rally cars were converted by Michelotto, a Ferrari dealership founded in 1969. It wasn’t until the mid-1980s that Ferrari’s Group B ambitions would start materializing via the 288 GTO Evoluzione. The Evoluzione, unveiled in 1986, was an extreme Group B homologation prototype built with clear competition intent. However, Group B’s 1986 cancellation stalled the model’s effort to develop into a race program.AdvertisementAdvertisementRelated: The 4 Cars That Funded Enzo Ferrari’s Racing DreamsGroup B cars started at around 300 horsepower in 1982, with those levels rapidly rising to 400, 500, and 600. This power, combined with insufficient safety tech, low vehicle control margins, lightweight cars, undeveloped driver aids, and a lack of crowd control, led to the sport’s cancellation. At the Rally de Portugal, a Ford RS200 lost control on a fast section, left the road, and crashed into spectators. Three died, and about 30 others were seriously injured. Around 8 weeks later, the Tour de Corse (Corsica Rally) in France saw Henri Toivonen and co-driver Sergio Cresto killed after lifting off the ground, tumbling down a mountain, and erupting into flames in their Lancia Delta S4. With Group B rallying over following these tragedies, Ferrari was left with unused race-developed engineering. However, the Italian automaker didn’t fully abandon its 288 GTO Evoluzione’s ideas. Instead, much of this prototype’s engineering philosophy directly influenced the F40.RM Sotheby'sView the 5 images of this gallery on the original articleFerrari saw the Porsche 959 changing what a supercar could beGroup B’s end wasn’t the only 1986 factor influencing the F40’s genesis. That same year, Porsche released its 959, the most technologically advanced supercar of the 1980s, and generally deemed the first hypercar. The 959 pioneered all-wheel drive (derived from the manufacturer’s Group B rally development program) for Porsche sports cars, registered a blistering 3.7-second 0-60 mph time, and included automatic ride-height adjustment for superior aerodynamics. Still, Ferrari wasn’t going to let Porsche have the last word in defining 1980s supercar performance, and they let their actions do the talking. The company’s founder, Enzo Ferrari, had approved a development direction for a lighter, rawer, and purely performance-focused car in the mid-1980s. This effort evolved through the 288 GTO Evoluzione before becoming the F40.Need new tires? Save up to 30% at Tire RackFind the perfect tires for your exact vehicle and driving style.

A blend of Kevlar and fiberglass significantly reduced the model’s weight to just 2,072 lbs, including a huge carbon fiber rear wing. It used the standard road-going 288 GTO’s 2.8-liter V8 engine, but added larger turbochargers and more refined engine tuning, increasing horsepower from 400 to 650. Group B’s death meant that only six of the 20 planned 288 GTO Evoluzione examples were built. AdvertisementAdvertisementChunks of Ferrari 288 GTO Evoluzione philosophy flowing into the F40 included the twin-turbo V8 concept, advanced lightweight materials (further expanded), more aggressive aerodynamic development, and a stronger race-car-for-the-road ethos. Compared to its 288 GTO predecessor, the F40 increased horsepower by up to 78, shaved up to one second off its counterpart’s 0-60 mph time, and became the first street-legal production car to exceed 200 mph. The F40 also weighed 132 lbs less than the 288 GTO at 2,425 lbs. Enzo Ferrari’s final era and the ideology that defined the F40The F40 was the last production Ferrari personally approved by Enzo, with its 1987 release aligning with the brand’s 40th anniversary. This halo Ferrari wasn’t a reaction to a single influence. Instead, Group B’s collapse, a shifting 1980s supercar landscape via models like the Porsche 959, and 288 GTO Evoluzione philosophy spurred the model’s creation. The F40’s extreme lightness, turbocharged performance, and stripped interior facilitated a raw driving experience, contrasting with flashier competitors at the time like Lamborghini’s Countach and establishing what enthusiasts consider Ferrari’s last true analog car. In other words, Ferrari showed that limitations and deliberate lack of refinement could create one of the greatest cars ever during a decade of excess. While people still glorify Group B rallying, its continuation could mean that the F40 wouldn’t occupy the same cultural space.
