By 1954, the first of Chrysler's CR gas turbine engines designed for cars was ready. Dubbed "CR1" and rated at a modest 100 horsepower, it was installed in a stock-looking 1954 Plymouth Belvedere hardtop that ran successfully at the opening of Chrysler's new Chelsea, Michigan, proving grounds. A similar engine went into a 1955 Belvedere four-door.

Improvements followed thick and fast. A modified CR1 with more exotic metallurgy powered a 1956 Belvedere "Turbine Special" sedan on a cross-country run that year. It performed well except for returning only 13 miles per gallon, excessive even for those times.

Next came a more efficient CR2 with about 200 horsepower, aided by cheaper but sturdier alloys that better withstood heat and oxidation.

This powered a second 1956 Plymouth sedan as well as a 1957-58 version before making its public debut in a 1959 Fury-based Turbine Special hardtop sedan. That car turned in a more creditable 18 mpg on a 1,200-mile demonstration run from Detroit to Princeton, New Jersey.

The third-generation CR2A was ready by 1960. Its two big advances were a pivoting fuel nozzle mechanism and first-stage turbine vanes that could assume one of three angles depending on throttle position.

Together, these provided a measure of engine braking (the lack of which was a serious drawback of turbine engines), plus stronger acceleration; they also greatly reduced the irritating "throttle lag" that had plagued earlier versions. Where the CR1 needed a full seven seconds to go from idle to full power output, the CR2A took only 1.5-2.0 seconds.

CR2As were initially installed in three different 1960 vehicles: a near-stock Plymouth Fury hardtop, a 2.5-ton Dodge truck, and the amazingly befinned TurboFlite, which wasn't shown until 1961.

The last was designed by Maury Baldwin, who later termed it the final "Virgil Exner" show car: "We incorporated a lot of interesting things in it. Entrance-wise, the whole cockpit above the beltline lifted to admit passengers. Mounted between the fins was a deceleration flap, such as used on racing cars. The headlights were retractable. The car was built by Ghia; we did a 3/8-scale model and then full-size drawings. It was probably one of the best engineered show cars we ever did."
