Front-wheel drive had previously been introduced to small, inexpensive cars by BMC, firstly with the Mini in 1959 and then with the larger 1100/1300 series in 1962. During the mid-1960s, Fiat set about designing a new car to compete with the latter. The BMC design of Alec Issigonis had the transmission and engine sharing a single oil sump — despite disparate lubricating requirements — and located the engine's radiator at the side of the engine, away from the flow of fresh air and drawing heated rather than cool air over the engine. The layout often required the engine to be removed to service the clutch.
