The 1908 Grand Prix season was the third Grand Prix racing season. An international economic recession affected motor-racing with fewer races and smaller fields. However, in consequence, it also saw an increase in the number of smaller cars and voiturette racing. This gave close racing between the teams from Lion-Peugeot, Sizaire-Naudin and Delage. Both the major races in Europe, the Targa Florio and French Grand Prix, had precursor voiturette races, and along with the Coupe des Voiturettes, the honours were shared between those three manufacturers.This year’s Targa Florio had a small, but quality, field. Vincenzo Trucco won for Isotta-Fraschini with better mechanical reliability, after a close duel with the FIATs of Felice Nazzaro and Vincenzo Lancia.
