The Ford Model T used a 177 cu in (2.9 L) sidevalve, reverse-flow cylinder head inline 4-cylinder engine. It was primarily a gasoline engine. It produced 20 hp (14.9 kW) for a top speed of 45 mph (72 km/h). It was built in-unit with the Model T's novel transmission (a planetary design), sharing the same lubricating oil.

The T engine was known for its simplicity, reliability, and economy. The engine remained in production for many years, and millions of units were produced. The engine design's lifespan exceeded that of the Model T vehicle itself, with industrial, marine, and military applications extending its production run. The T engine is on the Ward's 10 Best Engines of the 20th Century list.
