The Ford Model T (colloquially known as the Tin Lizzie, Tin Lizzy, T‑Model Ford, Model T, or T) is an automobile that was produced by Henry Ford's Ford Motor Company from October 1, 1908, to May 26, 1927. It is generally regarded as the first affordable automobile, the car that opened travel to the common middle-class American; some of this was because of Ford's efficient fabrication, including assembly line production instead of individual hand crafting. The Ford Model T was named the world's most influential car of the 20th century in an international poll.

The Model T had a front-mounted 177-cubic-inch (2.9 L) inline four-cylinder engine, producing 20 hp (15 kW), for a top speed of 40–45 mph (64–72 km/h). According to Ford Motor Company, the Model T had fuel economy on the order of 13–21 mpg-US (16–25 mpg-imp; 18–11 L/100 km). The engine was capable of running on gasoline, kerosene, or ethanol, although the decreasing cost of gasoline and the later introduction of Prohibition made ethanol an impractical fuel for most users. The Model T was a rear-wheel drive vehicle. Its transmission was a planetary gear type billed as "three speed". In today's terms it would be considered a two-speed, because one of the three speeds was reverse.

Model T engines continued to be produced until August 4, 1941. Almost 170,000 were built after car production stopped, as replacement engines were required to service already produced vehicles.
