Platform Heritage

The Honda Civic (Japanese: ホンダ・シビック, Hepburn: Honda Shibikku) is a series of automobiles manufactured by Honda since 1972. As of 2023, the Civic is positioned between the Honda Fit/City and Honda Accord in Honda's global passenger car line-up. It is one of the best-selling automobiles in history, with over 27 million units sold through 2021. The first-generation Civic was introduced in July 1972 as a two-door fastback sedan, followed by a three-door hatchback that September. With a 1,169 cc transverse engine and front-wheel drive, the car provided good interior space despite its small overall dimensions. Initially gaining a reputation for being fuel-efficient, reliable and environmentally friendly, later iterations have become known for performance and sportiness, especially the Civic Si, SiR, and Type R versions. It is currently in its eleventh generation, which has been produced since 2021. The Civic has often been rebadged for international markets, and it served as the basis for the Honda CR-X, the Honda CR-X del Sol, the Concerto, the first generation Prelude, the Civic Shuttle (which later became the Orthia) and the CR-V (which in turn was used as the basis for the Honda FR-V).
