O. Bentley put the word out to his team to line up for a formation finish. Quite a novelty at the time, the “Motor” magazine described it as “superb, disposed in line ahead like a squadron of battleships.” Bouriat/Rothschild bought the Stutz home in fifth, barely a lap ahead of the hard-charging Benoist in his Chrysler, with his teammate three laps further back. Ken Peacock's privateer Lea-Francis was the first smaller-engined car, in eighth, with two of the Tractas rounding out the ten finishers. Team-owner Grégoire almost had a race-ending spin at Arnage near the end of the race, but they were the only French cars to finish this year. It was the most dominant display by a manufacturer in the short history of the race to date, and not matched until 1957 by Jaguar. The leading two Bentleys had not missed a beat. In the mighty Speed Six, Tim Birkin had stamped an impressive new lap record, fully 46 seconds faster, helped by the slightly abbreviated track layout. They also broke the race distance record, covering over . The Speed Six's performance was so strong that they also won all three major awards, becoming the biggest car to win the Index. In finishing fourth, Frank Clement has the distinction of being the only driver to have participated in all seven of the Le Mans through the 1920s, all for Bentley and including the distance victory in 1924. Feeling very pleased with his consecutive victories, Barnato loaned Bentley another £25000. In August, the innovative supercharging pioneer René Cozette was killed making a speed-record attempt when he crashed at 200 kp/h at Montlhéry.In November, Kidston was badly burned when he was the sole survivor in an air-crash in England of a Luft Hansa passenger flight.
