Introduced in September 1991 for the 1992 model year, the redesigned Civic featured increased dimensions, as well as more aerodynamic styling. The wagon variant was now only available in the Japanese market where the previous generation wagon was carried over until 1995. The efficiency of the previous HF model was replaced by the VX hatchback which, with an EPA rating of 48/55 MPG, was Honda's most fuel efficient model sold at the time. In North America, the Si featured a 1.6-liter SOHC VTEC valve train, whereas the VX featured the VTEC-E. The Japanese Si featured a 1.6-liter DOHC non-VTEC valve train D16A9. Continuing in the sporty tradition of the original Civic SiR, Honda sold several similarly equipped variants of the fifth generation car, still referred to as the Civic SiR, in Japan, Asia and Europe. In South Africa, MBSA (Mercedes Benz of SA) built the Civic as the Ballade only in 4-door sedan. A special model was the 180i with the B18B4, that was fitted to Ballade models. A new body style was introduced with this generation called the Civic Coupé, based from the Civic Ferio sedan, and was sold in North America, Europe and Japan. The fifth-generation remains popular among tuners and racers alike.
