among the top ranked non-works entries. Group B Following the introduction of Group B rules in 1982, Michelotto began building 308 GTB rally cars to compete in that class. The first Gr.B 308 was built at the request of Spanish rally driver Antonio Zanini. Four Gr.B specification cars were built, with certain engine and bodywork details differing from the earlier Gr.4 cars. The first Gr.B 308, chassis 18869, was constructed with a 2-valve engine like the Gr.4 cars, while the 3 later cars used a 4-valve-per-cylinder engine and Bosch K-Jetronic fuel injection from the 308 Quattrovalvole. The QV motor produced 310 hp at 8,000 rpm after tuning by Michelotto. The Gr.B cars were also equipped with a "quick-change" gearbox that allowed the final drive ratio to be replaced quickly and easily during racing or testing. Additional modifications included upgraded Brembo brakes, Fondmetal Canonica wheels, stronger anti-roll bars, rose-joint suspension links, lighter suspension wishbones and a quicker-ratio steering rack. As initial homologation rules required that Gr.B cars use the same body panels as their roadgoing counterparts, the Gr.B 308s were equipped with steel and fiberglass panels. This increased total weight by over the earlier Gr.4 cars. The 308 was homologated under Group B rules three separate times in October 1982, January 1983 and April 1983. This allowed Michelotto to incorporate additional Ferrari-made performance parts into their Gr.B cars, including engine parts, lightweight windows and body panels. In 1983, chassis 18869 was driven to first-place finishes at several rallies, including the Imperia Rally and the Sicilian Rally Championship. In 1985, Antonio Zanini drove this car to a third-place finish at the Targa Florio, followed by several other wins which led to his victory in the Spanish Rally Championship. At the 1984 Rally Della Lana, Luigi "Lucky" Battistolli and Claudio Berro drove chassis 18847 to a second-place finish. Also in 1984, the same car was driven to a third-place finish at the Rally di Monza by Björn Waldegård and co-driver Claes Billstam. 308 GT/M The Ferrari 308 GT/M was developed by Ferrari and Michelotto to compete under the Group B "Evolution/Termination" rules. Development began in November 1982 as the successes of the Gr.4 308 convinced Ferrari and Michelotto that a purpose-built Ferrari rally car could be competitive under Group B rules. The model was cancelled with the banning of Group B cars for the 1987 season. The 308 GT/M was built on a
