Ariès was a new entrant this year and arrived with four cars. It was founded in 1903 by former Panhard et Levassor engineer "Baron" and had competed in the early inter-city races. Two shortened GP versions of the standard Type S were prepared, one with a 3.2-litre and the other with a 3-litre engine. There were also two 1100cc cars entered: an older CC2 and a new CC4 4-seater. Getting back into post-war racing in 1924 Petiet assembled a team of well-known drivers. Fernand Gabriel was leading the ill-fated 1903 Paris-Madrid race when it was stopped. Arthur Duray had set land speed records before the war and finished second in the 1914 Indianapolis 500 behind René Thomas. Robert Laly had been Thomas’ riding mechanic in the same race.
