Bentley 3 Litre

Bentley 3 Litre

The Bentley 3 Litre, produced from 1921 to 1929, was the car that founded the Bentley legend. Designed by Walter Owen Bentley — universally known as W.O. — it was built around a single, clear philosophy: to create a fast car, a good car, and the best in its class. The 3 Litre delivered on this promise spectacularly, becoming one of the defining sports cars of the 1920s and establishing Bentley's reputation for combining performance with rugged reliability.

W.O. Bentley had made his name before World War I as an innovative engineer who introduced aluminium pistons to British aero engines — a development that significantly improved the performance and reliability of Allied aircraft. After the war, he applied the same engineering principles to his first car. The 3 Litre featured a 2,996cc single-overhead-camshaft four-cylinder engine with four valves per cylinder — remarkably advanced for 1919 when the design was finalized. The engine was built to extraordinarily robust tolerances, reflecting W.O.'s belief that reliability was paramount.

The chassis was equally substantial — a stiff ladder frame that could accept various coachwork from the leading body builders of the era. Most 3 Litres were fitted with open touring bodies, though saloon, drophead coupe, and sporting bodies were also available. The car was large and heavy by the standards of its class, but W.O. Bentley believed that strength and durability were more important than outright lightness.

The 3 Litre's competition career was stellar. It won the 24 Hours of Le Mans in 1924 — the second running of the great race — driven by John Duff and Frank Clement. This victory established Le Mans as a Bentley hunting ground. The 3 Litre won Le Mans again in 1927 (driven by the 'Bentley Boys' trio of Sammy Davis and Dudley Benjafield), in what remains one of the most dramatic Le Mans races ever run — Davis's badly damaged car limped across the line to take an unlikely victory after a multi-car pile-up at White House corner.

The 'Bentley Boys' — a group of wealthy, aristocratic young men who raced Bentleys with extraordinary bravery and panache — became synonymous with the 3 Litre and its successors. Figures like Woolf Barnato, Glen Kidston, Tim Birkin, and Davis created a legend of sporting heroism that remains central to the Bentley brand identity a century later.

Over its production life, the 3 Litre was offered in several specifications. The standard (Blue Label) model produced approximately 65-70 hp, while the Speed Model (Red Label) offered around 80 hp. The later Super Sports (Green Label) models, the rarest and most desirable, produced approximately 85-90 hp. The 100 mph models from the mid-1920s could genuinely achieve the magic ton — a remarkable feat for a 3-litre car of that era.

A total of 1,622 three-litre Bentleys were produced at the Cricklewood factory between 1921 and 1929. Today, the 3 Litre is among the most prized vintage Bentleys, with Le Mans team cars and Super Sports models commanding the highest values. Its significance as the founding model of one of the world's most prestigious automotive brands ensures enduring collectibility.
