In 1906-1907, Ford's first straight-6 engine was introduced in the Model K. Henry Ford did not like the car because the engine could overpower its transmission.

The next Ford six was introduced in the 1941 Ford. The Ford Motor Company of America continued producing straight-six engines until 1996, when they were discontinued in favor of more compact V6 designs. Ford Australia manufactures these engines for their Falcon and Ford Territory vehicles.

The first-generation Ford six-cylinder engines were all flatheads. They were the G- and H-series engines of 226 cu in (3.7 L) used in cars and trucks and the M-series of 254 cu in (4.2 L) used in larger Ford trucks and for industrial applications.

Introduced with the 1941 model year, the first Ford L-6 (designated G-series) displaced 226 cu in (3.7 L) and produced 90 hp (67 kW), the same as the Flathead V-8 that year. Like the V-8, it was also a flathead or L-head engine. In 1948, Ford raised the compression of the flathead six or L-6 (designated H-series or Rouge 226) so that it generated 95 hp (71 kW) and 180 lb·ft (244 N·m) of torque. The G- and H-series engines were used in the full-sized Ford cars and trucks to replace the smaller 136 cu in (2.2 L) Flathead V8 that were used with the 1937 Ford. Ford discontinued production of the H-series engine with the 1951 model year.

A 254 cu in (4.2 L) version of the L-6 (designated the M-series or Rouge 254) was used from 1948 to 1953 in F6-series Ford trucks (COE, Dump, semi-, etc.), and small Ford school buses. The M-series engine produced 115 hp (86 kW) and 212 lb·ft (287 N·m). of torque. They were also used in miscellaneous industrial applications. e.g., to power water pumps for irrigation purposes and within wine-producing farms to manage risk by powering giant frost-control propellers on stands in the middle of rows of grapes.
