Available in sedan or coupe bodies, all but the Si trim are powered by a 140 horsepower, 1.8-liter inline four-cylinder with a standard five-speed manual transmission and optional five-speed automatic. The performance-oriented Si comes with a 197 horsepower, 2.0-liter inline-four bolted only to a six-speed manual. Standard safety features on all Civics include anti-lock brakes, six airbags, active front head restraints, daytime running lights and tire pressure monitoring. Electronic stability and traction control is standard on the EX-L trim. The Civic is unchanged for 2011.
