The 1909 Grand Prix season was the fourth Grand Prix racing season. There were no Grandes Épreuves that year, as the economic recession of the previous year continued on. Renault had withdrawn from motor-racing and a number of French manufacturers, falling behind the success of their German and Italian rivals, followed suit. The French Grand Prix was cancelled, leaving the Targa Florio in Italy and Vanderbilt Cup in the United States as the only major races this season. With so little competition and financial incentive, technological advances ground to a halt. Emphasis shifted from racing to setting speed and endurance records. Benz & Cie built a new 12.4-litre racing-engine, and its 200 bhp derivative was put into the Blitzen Benz. This 21.5-litre monster held the Land speed record from 1909 to 1922, with various drivers starting with Victor Hémery in November, 1909 at Brooklands.

S.P.A. was an Italian automobile, military vehicle and aero-engine manufacturer founded in Turin by Matteo Ceirano and Michele Ansaldi. It was active between 1906 and 1926. In 1908, it merged with Fabbrica Ligure Automobili Genova (FLAG) and the new company, Società Ligure Piemontese Automobili, was headquartered in Genoa while manufacturing in Turin.
