The 2011 Honda Civic offered several engine options depending on the trim: a 1.8-liter four-cylinder for most models, a 2.0-liter four for the Civic Si, and a 1.5-liter hybrid powertrain for the Civic Hybrid. A rare Civic GX variant used a natural-gas version of the same base 1.8-liter engine.
In 2011, Honda lined up the Civic with choices designed to balance everyday practicality, spirited driving, and alternative-fuel options. The following breakdown covers the main powerplants that powered the 2011 Civic family.
