The race was run under a new formula agreed in Ostend in 1907. There was no fuel consumption limit, but the cars had a minimum weight of 1100 kilograms, and a maximum cylinder bore of 155 millimetres. This formula differed from the regulations in place for the American
Vanderbilt Cup series, which discouraged American manufacturers from entering the race. Lewis Strang drove the single American entrant, the
Thomas Flyer.
D. Napier & Son cars were disqualified from the race due to their use of
Rudge-Whitworth center locking hubs, which the organizers believed were unsafe. ==The Race==
