The Mitsubishi-built 3.0-liter V6, introduced as an option for 1990, develops 141 horsepower. The V6 might be found in any LeBaron that year except the GTC, which employed Chrysler's new 2.2-liter intercooled VNT (Variable Nozzle Turbo) Turbo IV engine, making 174 horsepower. Only a 5-speed manual transmission could be installed in the GTC, but other LeBarons might have either manual shift or a 3-speed automatic; or, for the first time, a 4-speed automatic that was standard on some models, optional on others. Base engine was a 2.5-liter 4-cylinder. A V6 went into LX and GTC models for 1991. The potent 2.2-liter turbo disappeared that year, in favor of a 2.5-liter that could go into either a base LeBaron or GTC.
