Fiat's Grand Prix car for 1907 was meant to end French dominance once and for all. That year a new formula was introduced based on fuel consumption (a maximum of 30 liters per 100 km/9.42 mpg) without any weight or engine capacity limits. Fiat introduced a car designed by Giovanni Enrico which was powered by a 4 cylinder 16,00cc engine. The engine producing 130 bhp weighed more than 2000lbs! Each piston weighed almost ten pounds. Other features included hemi-spherical combustion chambers, centrally placed spark plugs and a Simms-Bosch magneto ignition.

Its first race of the season came at the Targa Florio in Sicily. The new Fiats scored a 1-2 with Felice Nazzaro leading Vincenzo Lancia. The most important race on the calendar was the French Grand Prix at Dieppe. This was also won by Nazzaro who set fastest lap for good measure. The successful season was capped by victory at the Kaiserpreis.
