Chrysler Corp. and Mitsubishi Motors Corp. are gearing up to produce their next generation of joint-venture cars, which will include two- and three-door sport cars and a four-door sedan.

The new models will be produced by Diamond-Star Motors Corp., the companies’ 50-50 venture in Normal, Ill.

Diamond-Star, incorporated in 1985, produces the Mitsubishi Eclipse and Mirage, Plymouth Laser and Eagle Talon and Summit models.

The U.S. and Japanese companies said they may increase the American content of Diamond-Star’s new vehicles by using Chrysler-built engines and transmissions in some models.

The vehicles will be distributed in equal numbers for sale by Chrysler and Mitsubishi Motor Sales of America.

Discussions are continuing on other new vehicles, including timing of the production launch and volume of each model, the car makers said.
