The new 312 (3-litre, 12 cylindres) and 316 (3-litre, 16 cylindres) were entered, but they got engine trouble during practice and Clemente Biondetti took the start at the wheel of the 308 held in reserve.

In 1949 the 166MM barchetta also won the 24 Hours of Le Mans (driven by Luigi Chinetti and Lord Selsdon) and the Targa Florio (with Clemente Biondetti and Igor Troubetzkoy), the only car ever to win all three races in the same year.
The factory entered three, whose driver pairings were Stirling Moss and Jack Fairman, Leslie Johnson and 3-times Mille Miglia winner Clemente Biondetti, and the eventual winners, Peter Walker and Peter Whitehead.
