On 13 December 2010, Honda unveiled a sketch of the new ninth-generation Civic which was described as "energetic, sleek and aerodynamic." Both coupe and sedan concepts were shown on 10 January 2011 at the 2011 North American International Auto Show. The production version of the ninth-generation Civic (previewed by the concept) went on sale in the U.S. on 20 April 2011. In late 2012, Honda updated its Civic model with new exterior and interior trims for the 2013 year.
Honda's Eco Assist technology is added to most models, and became the first gasoline-only powered Honda to employ such technology in North America. It is an information system to help the driver adopt a more fuel-efficient driving style, and is proven to improve fuel economy by about 10% for Honda's hybrid vehicle in Japan.
All models now come standard with ABS (Anti-Lock Brake Systems), VSA (Vehicle Stability Assistance) and EBD (Electronic Brake Distribution). Further improvements include a new multilink rear suspension to further reduce road feel on particularly battered roads and highways.
Following its launch, the new model was widely panned by the automotive press due to the poor quality of its interior and ride, and for the first time, it failed to earn a Consumer Reports recommendation. In an unprecedented move, Honda made significant interior and exterior redesigns the following year to address these issues, but market share in the compact car segment showed a marked decline from the previous generation.
