ABF (United Kingdom) - AllCarIndex

The A.B.F. (All-British Ford) was a British automobile brand founded in 1923 by Canadian-born Robert O. Ford in Kenilworth, Warwickshire. The brand aimed to distinguish itself from the more established Ford products by adopting the name A.B.F. to emphasize its British origins.

The A.B.F. featured a unique V4 2-stroke engine, with a displacement of 1216cc. This innovative engine design allowed each cylinder to deliver a charge to its neighbor during the firing stroke, similar to the design used in the Trojan vehicles. The car was equipped with a 3-speed gearbox integrated with the engine, and it utilized a shaft drive to a worm rear axle, although there were plans to replace this with a spiral bevel design. The body of the A.B.F. was derived from a racing 10/30 Alvis, while the production model was intended to be a 3-door, 4-seater tourer.

In addition to the A.B.F., Ford also developed a more conventional light car featuring a 4-stroke flat-twin engine. However, only one unit of each model was produced, and the 2-stroke variant is known to have survived to this day.
