The Bentley Boys were a group of wealthy British motorists who drove Bentley sports cars to victory in the 1920s and kept the marque's reputation for high performance alive. In 1925, as the marque foundered, Bentley Boy Woolf Barnato bought the company, leading to the creation of the famous supercharged Bentley Blower car.

The Bentley 4½ Litre was a British car based on a rolling chassis built by Bentley Motors. Walter Owen Bentley replaced the Bentley 3 Litre with a more powerful car by increasing its engine displacement to 4.4 litres (270 cubic inches).
Bentley buyers used their cars for personal transport and arranged for their new chassis to be fitted with various body styles, mostly saloons or tourers. However, the publicity brought by their competition programme was invaluable for marketing Bentley's cars.
At the time, noted car manufacturers such as Bugatti and Lorraine-Dietrich focused on designing cars to compete in the 24 Hours of Le Mans, a popular automotive endurance course established only a few years earlier. A victory in this competition quickly elevated any car maker's reputation.
A total of 720 4½ Litre cars were produced between 1927 and 1931, including 55 cars with a supercharged engine popularly known as the Blower Bentley. A 4½ Litre Bentley won the 24 Hours of Le Mans in 1928. Though the supercharged 4½ Litre Bentley's competitive performance was not outstanding, it set several speed records, most famously the Bentley Blower No.1 Monoposto in 1932 at Brooklands with a recorded speed of 222.03 km/h (138 mph).
Today, Bentley 4½ Litre automobiles from this inter-war period – the "Belle Époque" of the automobile for some  – sell for around €1,000,000. Blowers can fetch more than €7 million and are coveted by collectors despite never winning a single race.For many, the 4½ Litre is to automobiles what the Spitfire is to aircraft
