the Chrysler Turboflite concept car. Refined CR2A turbines were installed into a 1962 Dodge Dart and Plymouth Fury; the Dart was driven from New York City to Los Angeles in December 1961, and the Fury completed a journey from Los Angeles to San Francisco in January 1962. After Huebner arrived in Los Angeles with the Dart, he spent two hours giving journalists rides in the turbine-powered car. Chrysler had barnstormed its fleet of turbine cars to dealers across North America, Europe, and Mexico by February 1962, visiting 90 cities, giving rides to almost 14,000 people, and being seen by millions more. The third-generation turbine program ended at the 1962 Chicago Auto Show that month, where the company displayed its turbine-powered fleet. Shortly before the show, Chrysler announced an upcoming fourth-generation turbine engine it planned to install in a limited run of 50–75 cars which would be loaned to the public at no cost in late 1963, a decision largely due to enthusiastic public response to the barnstorming tour. Engine The Chrysler Turbine Car is powered by the A-831, Chrysler's fourth-generation turbine engine. The most notable difference from its predecessor, the CR2A, was its use of twin regenerators (one mounted on either side of the gasifier) instead of a single top cover-mounted heat exchanger. This design helped the A-831 trim from the CR2A's weight, reducing it to a relatively light . Huebner described the turbine as similar to a jet engine, noting that it had only one spark plug and about 80% fewer parts than a typical automotive piston engine. Due to their construction, the engines did not require antifreeze, a cooling system, a radiator, connecting rods, or crankshafts. The A-831 could operate on diesel fuel, unleaded gasoline, kerosene, and JP-4 jet fuel; leaded gasoline damaged it. According to Chrysler, it could burn a variety of unusual fuels ranging from furnace oil and perfume to peanut and soybean oils. Mexican President Adolfo López Mateos ran one of the cars on tequila after Chrysler engineers confirmed that it would do so. The engine produced at 36,000 revolutions per minute (rpm), of torque, and idled between 18,000 and 22,000 rpm. At idle, its exhaust did not exceed . When driven at , the turbine ran at its maximum of 60,000 rpm. The A-831's compressor had a pressure ratio of 4:1 and an efficiency of 80%; its combustor operated at 95% efficiency. Compared to
