Ford straight-six engine

The Ford straight-six engines are the inline six-cylinder engines that Ford Motor Company produced from 1906 until 1908 and again from 1941 until 2016. The first was introduced in 1906 in the Model K, and the next in the 1941 Ford. Ford kept building straight-sixes for its North American vehicles until 1996, when they gave way to more compact V6 designs, while Ford Australia built them for the Falcon and Territory until 2016, when both lines ended. With the closure of the Australian engine plant Ford no longer produces a straight-six gasoline engine. The first generation were all flatheads: the G- and H-series of 226 cubic inches (3.7 litres) used in cars and trucks, introduced for the 1941 model year at 90 hp, and the M-series of 254 cubic inches (4.2 litres) used from 1950 to 1953 in F6-series trucks and small school buses and in industrial jobs such as irrigation pumps and vineyard frost-control propellers. The second generation was a newly designed inline-six produced from 1952 through 1964.
