The 2007 Honda Civic FD was mainly offered with two petrol engine options, depending on the market: a 1.8-liter i-VTEC inline-4 for most trims and a higher-performance 2.0-liter i-VTEC inline-4 used in the Civic Si variant. Power outputs vary by market and transmission, but these are the core engines associated with the FD generation in 2007.
