The Bentley Boys included:[citation needed] Thanks to the dedication of this group to serious racing, the company, located at Cricklewood, north London, was noted for its four consecutive victories at the 24 hours of Le Mans from 1927 to 1930.
Their greatest competitor at the time, Bugatti, whose lightweight, elegant, but fragile creations contrasted with the Bentley's rugged reliability and durability, referred to them as "the world's fastest lorries".
In March 1930, during the Blue Train Races, Woolf Barnato raised the stakes on Rover and its Rover Light Six having raced and beaten Le Train Bleu for the first time, to better that record with his 6½ litre Bentley Speed Six on a bet of £100.
He drove against the train from Cannes to Calais, then by ferry to Dover and finally London, travelling on public highways, and won.
The H. J. Mulliner-bodied formal saloon he drove during the race, as well as a streamlined fastback "Sportsman Coupe" by Gurney Nutting delivered to him on 21 May 1930 became known as the Blue Train Bentleys.
