Bentley buyers purchased a rolling chassis and selected their desired bodies, mostly Saloons and Tourers, to be built to their own specification from a variety of independent coach builders. 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 The 4½ litre was a heavy car, weighing 1,625 kg (3,583 lb), and spacious, with a length of 4,380 mm (172 in) and a wheelbase of 3,302 mm (130.0 in), it was also well balanced and with nimble handling. The robustness of the 4½ Litre's lattice chassis made of steel and reinforced with ties, was needed to support the heavy cast iron inline-four engine. The 4398cc engine was fed by twin SU carburettors and dual ignition with Bosch magnetos with an output of 110hp for the touring model and 130 hp for performance and racing models, with the engine speed limited to 4000 revs. A single, crossflow, overhead camshaft actuated four valves per cylinder, inclined at 30 degrees. This was a technically advanced design at a time where most cars used only two valves per cylinder in a side-valve cylinder head. The camshaft was driven by bevel gears on a vertical shaft at the front of the engine, as on the 3 Litre engine. Brakes were conventional, consisting of 17-inch (430 mm) drum brakes finned for improved cooling and operated by rod. Semi-elliptic leaf springs were used at front and rear VR 1523 Delivered new in July 1929 to its first owner T F Francopula, originally fitted with a Vanden Plas fabric two seater, with double dickey seats and a three piece screen, now sporting a four seater body by Tonwsend Diolch am 95,917,405 o olygfeydd anhygoel, mae pob un yn cael ei werthfawrogi'n fawr.
