The 1928 24 Hours of Le Mans was the 6th Grand Prix of Endurance that took place at the Circuit de la Sarthe on 16 and 17 June 1928. Bentley director Woolf Barnato and Australian-born Bernard Rubin in a Bentley 4½ Litre gave the company back-to-back victories after a race-long duel with the Stutz of Édouard Brisson and Robert Bloch. In the process they won the inaugural prize for overall distance. Salmson achieved consecutive victories in the Biennial Cup, while the new car from Bollack Netter and Co won the Index of Performance.
