The Course:
The course near the French city of Strasbourg was roughly a triangular of unpaved public roads with three near straights and three sharp corners. The start line where elaborate viewing tribunes and fronting ‘pits’ were built was at Duppigheim, first corner was at Enzheim, second at Innenheim, and final corner at Duttlenheim. It was 8.31mile long, requiring 60 laps to complete the 498.89 miles.

The 1922 Grand Prix de l’ACF:
In practice it became clear that the Fiat team had superior speed; Sunbeam axle ratio were lowered to improve speed. In the race, the Sunbeams could not match the performance of the Fiats, safe engine revolutions were exceeded and the inlet valves fractured; the Sunbeams were ‘put out of running’. Jean Chassagne in car No.9, the team leader and winner of that year’s IoM T.T. retired after only five laps as did K L Guinness in car No.16. Segrave, in car No.21, the junior team member, in his second ever Grand Prix lasted ‘approximately half the full distance’. He was later to remember this event as ‘sheer misery’ (not least due to chemical fuel burns on his backside sustained by fuel spillage, the result of a hurried and untidy refueling) ; he did hold a fourth place behind the Fiats for most of his race.
