The 1899 Frederick Lanchester car was the first to be designed entirely in Britain. His horizontally-opposed 4033cc engine was very distinctive, with opposed pistons connected to two crankshafts rotating in opposite directions by two connecting rods. It was a strange engine, but it was an engine that spun wonderfully and smoothly. Even more surprising was that the cylinder had only one valve, which acted as both intake and exhaust valves. In 1901, Wilson Pilcher of the United Kingdom announced a car equipped with an advanced water-cooled flat 4 engine at the front. The flat 6 specification was completed in 1904, but now there is only one 4-cylinder engine.

In the United States Henry Ford was taking the first steps to become a car giant. In 1901, the one-off "Sweep Stakes" racer was loaded with a huge 7-inch horizontally opposed two-cylinder [593 cu-in = 9.7 liters!]. Ford's first mass-produced car was the 1903 Model A, but the engine was a 101 cubic inch [1668cc] flat twin, and the Models C and F were also similar boxer engine cars, but the legendary model was released in 1908. Model T had four in-line cylinders.

In the 20th century, front-mounted in-line or V-type multi-cylinder engines became commonplace in the automotive world, and the Flat 4 disappeared as if it had gone into hibernation. However, flat engines are suitable for aircraft and their history continues to this day.


In 1901, Wilson Pitcher announced an advanced car with a "quiet and vibration-free" water-cooled flat 4 on the front. In 1904 Flat 6 was also added.

The Blacksmith and talented engineer from Bradford, the Jouette brothers founded the company in 1901 and made several mistakes with the ambition to build a smaller car engine that was better than what was then commonplace. Later, in 1910, they finally launched a light car equipped with an 816cc water-cooled flat twin that had sufficient torque. The flat twin continued to be produced as a power unit for the "Bradford Van" until 1953 when Joe Wet stopped producing cars. It is also the longest-built British engine.

It wasn't until 1935 that Joe Wet put his hands on the Flat 4, but until the production was halted in World War II, the engine wasn't as popular as the Flat Twin. Conservative Joe Wet users preferred the old but sturdy and manageable twins.

Before World War I and after World War II, the popularity of the Flat 4 declined, while flat twin or V twin engines proliferated throughout Europe as lightweight cycle car and motorcycle engines. Literally produced by hundreds of manufacturers, the Morgan 3 Wheeler, launched in 1909, is the longest surviving car. In the United States, washing machines driven by flat twin engines were handy in rural areas where electricity was not drawn.
