a version of the 12-valve 1.3 was also on offer. Since first generation Mirages were still under Australian production as the Colt, all three third generation body types were sold under the Lancer name in that market. Initially, the Australian-specification models were designated as the CA series when introduced in 1988, adopting the CB designation for the 1990 facelift. The liftback continued to be sold in Australia alongside the fourth generation (CC) Mirage-derived Lancer from 1992 through to 1996. Confusingly, the carry-over liftback was also given this CC model designation. North American three-door and sedan sales occurred under the Mitsubishi Mirage name for the 1989 to 1992 model years.

Lancer variants sold in Japan offered unique body variants — a four-windowed sedan and, from May 1992, a station wagon simply named Mitsubishi Libero. This model was sold as the Lancer Wagon in most export markets, where its introduction coincided with a small update for 1993, featuring new bumpers and adjustments to the engine lineup.
