The Bentley 4½ Litre is a British sports car built by Bentley Motors. Its supercharged variant is also known as the Blower Bentley. Famous for his statement "there's no replacement for displacement", Walter Owen Bentley upped the displacement of the Bentley 3 Litre in 1926 to produce the 4½ Litre. Upon taking control of the company, the "Bentley Boys" went in search of even more power and developed the supercharged model in 1929 at Henry Birkin's racing workshops in Welwyn Garden City.
The 4½ Litre was an evolution of the 3 Litre, sharing that car's basic chassis, including its semi-elliptical suspension at all four wheels and four-wheel brakes. The straight-4 engine was bored out to 100 mm (3.9 in) to produce 4.4 L (4398 cc/268 in³) of displacement. This was good for 110 hp (82 kW) in road-going models or 130 hp (97 kW) when tweaked for racing.
A 4½ Litre Bentley claimed victory at the 24 Hours of Le Mans in 1928 with drivers Woolf Barnato and Bernard Rubin.
