1930 "Blower" Bentley
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 in 1932 at Brooklands with a recorded speed of 138 mph. Very few vintage Bentleys have survived with their four-seater coachwork intact. The inaugural 24 Hours race was held May 26–27 at Le Mans in 1927.
