The 2004 Honda Civic’s most common engines are a 1.7-liter inline-4 in the standard trims, with a 2.0-liter engine reserved for the high-performance Civic Si; there’s also a hybrid variant that uses a different powertrain, combining a petrol engine with electric assist.
In North America, the LX, EX and DX trims typically relied on the 1.7-liter engine, while the Civic Si used the larger 2.0-liter unit. The Civic Hybrid used a 1.3-liter gasoline engine paired with Honda’s IMA electric motor system. This article outlines those options and their basic characteristics.
