The Civic Sedan enters 2007 available in DX, LX, EX, GX, Hybrid, and sporty Si. While almost all the trims are equipped with a 140-hp 1.8L I-4 engine, the Si is powered by a 2.0L I-4 engine boasting 197 horsepower and 139 lb-ft of torque. The 1.8L powertrain is completed by either a five-speed manual or five-speed automatic transmission, while the 2.0L is offered in only a six-speed manual transmission. Standard equipment across the board includes side curtain airbags, daytime running lights, a theft-deterrent system, power convenience features, and ABS brakes. Higher trims upgrade by adding a premium audio system, body-colored exterior trim, air conditioning, cruise control, and a power moonroof. The Honda satellite-linked navigation system is also available on EX models.
