The 1977 Chrysler LeBaron Turbine: The Final Chapter of a 25-Year Experiment

The 1977 LeBaron was the culmination of nearly 25 years of Chrysler research into gas turbine engines. Ultimately, however, the program reached a dead end.

First, the 1963 Chrysler Turbine Ghia was not the beginning of the story. The automaker's ambitious gas turbine research program had started nearly a decade earlier, with the first-generation CR1 engine in 1954. It produced 100 horsepower but suffered from several drivability issues, including significant throttle lag and a lack of engine braking.

Continued development led to the fourth-generation A831 engine, which powered the now-famous Turbine Ghia. Chrysler built 55 of these cars, nine of which still exist today, with three reportedly remaining operational. The fourth-generation engine weighed just 399 pounds, produced 130 hp and 232 lb-ft of torque, and could run on almost any liquid hydrocarbon fuel, from kerosene to tequila.

After the Turbine Ghia's public demonstration program ended, development continued. Chrysler's engineers worked to address the familiar problems associated with gas turbines in passenger cars, including high fuel consumption and excessive exhaust emissions, particularly nitrogen oxides (NOx).

In 1972, the U.S. Department of Energy, which was actively exploring alternatives to gasoline and conventional internal combustion engines, provided funding and technical support for the project. The contract called for 14 test engines and several experimental vehicles. By then, the turbine had reached its seventh generation and could produce up to 123 hp while meeting applicable emissions requirements.

To demonstrate the Department of Energy program, Chrysler installed a seventh-generation turbine in the heavily redesigned 1977 LeBaron coupe featured here. Built on the M-body platform, the concept had a 112.6-inch wheelbase, a curb weight of approximately 3,880 pounds, and a three-speed TorqueFlite automatic transmission paired with the gas turbine.

Some of the front-end styling elements seen on the LeBaron Turbine concept later appeared on the production 1981 Imperial.

At the time, Chrysler seriously considered putting the turbine engine into limited production. Those plans came to an end with the Chrysler Corporation Loan Guarantee Act of 1979, better known as the Chrysler bailout. A committee overseeing government assistance, led by the Treasury secretary, concluded that the turbine-powered car was too risky and expensive for a company already facing severe financial difficulties.

Although the LeBaron concept marked the final chapter of Chrysler's passenger-car turbine program, it wasn't the last turbine-powered vehicle the automaker built. Chrysler also produced a turbine-powered 1981 Dodge Mirada, shown below.

Years after the program ended, a Chrysler turbine enthusiast tracked down the LeBaron and Mirada prototypes at a U.S. Department of Energy facility at a nuclear power plant in Ohio. Both cars have since been preserved in Stellantis' extensive historic vehicle collection, maintained by the company formerly known as Chrysler.
