A redesigned eighth-generation version of Honda's smallest model went on sale for the 2006 model year, with Honda calling it the most-changed Civic since the model was introduced to the U.S. market in 1973. Changes for 2008 include a new Mugen Si trim designed by Honda's high-performance tuner of the same name; there's also a leather package available for the first time on a Civic. Honda's Civic shares space in the compact class with the Volkswagen Jetta, Nissan Sentra, Chevrolet Cobalt and Toyota Corolla.
