Nannini was born in Siena. He began racing in a Lancia Stratos at national rally events before switching to Formula Italia in 1981. From 1982 to 1984, he raced for Minardi in Formula 2, attracting some attention for his speed in the uncompetitive car. Though his best season saw him only seventh overall in 1983, he was signed by Lancia to drive their fast but fragile LC2 prototype in the World Sportscar Championship, setting fastest lap at the 1984 24 Hours of Le Mans where he finished eighth with Bob Wollek, and later that year winning the 1984 1000 km of Kyalami with Riccardo Patrese. For 1985, Giancarlo Minardi wanted Nannini to drive his new Formula One car, but Nannini was controversially denied an FIA Super Licence with his former F2 teammate Pierluigi Martini taking the drive instead. Nannini continued with Lancia instead, his best result being third in the 1000km Monza.
