Chrysler built 50 cars powered by gas turbine engines in the early 1960s, loaned them to ordinary American drivers, and then destroyed nearly the entire fleet. The program represented the most ambitious attempt to replace the piston engine in a production passenger car, and its quiet cancellation locked the U.S. auto industry into a single powertrain path for decades. The story of the Chrysler Turbine Car is less about engineering failure than about an industry that chose not to follow through.
A Helicopter Engine Under the Hood
Chrysler’s gas turbine program began in the mid-1950s, when a team of engineers set out to adapt the same basic engine cycle used in helicopters and small aircraft for highway driving. The core idea was the regenerative cycle, a method of recapturing exhaust heat to preheat incoming air, which improved thermal efficiency compared to a simple turbine. George J. Huebner, the program’s lead engineer, presented the technical rationale in an SAE paper in 1964, explaining how the regenerative design allowed the turbine to function across a wide range of driving speeds rather than at a single optimal RPM. The engine could run on diesel, kerosene, jet fuel, or even perfume, a flexibility no piston engine could match.
A companion paper by Chrysler engineers G. DeClaire and A. H. Bell detailed the development methods used to validate the powerplant. Testing ranged from individual component fixtures to full powerplant endurance runs, demonstrating that Chrysler invested serious money and talent in proving the concept. This was not a concept sketch or a show car stunt. The company built real hardware, subjected it to real stress, and documented everything for peer review by the professional engineering community. Additional access to the regenerative turbine study and the related laboratory report on SAE Mobilus underscores how thoroughly Chrysler treated the turbine as a serious alternative to the conventional V-8.
50 Cars, 200 Families, and a Bold Experiment
By 1963, Chrysler was ready to put turbine cars in driveways. The company commissioned the Italian coachbuilder Ghia in Turin to hand-build the bodies for 50 cars, each finished in a distinctive bronze paint that earned the nickname “Turbine Bronze.” These were not prototypes hidden in a lab. Chrysler loaned them to selected American households for three-month stints, rotating through roughly 200 families between 1963 and 1964, according to the Smithsonian catalog entry for one surviving car. Drivers used them for commutes, road trips, and grocery runs, generating real-world data that no test track could replicate, while also giving the public a taste of a radically different driving experience.
A Chrysler corporate document published in August 1966, preserved by The Henry Ford, traces the full arc of the gas turbine vehicle program from its origins through its conclusion. That document confirms the 50-car public loan fleet and records the internal reasoning behind the program’s direction, including the decision to end consumer trials and focus remaining turbine work on controlled test vehicles. What makes this chapter so unusual in automotive history is the scale of consumer involvement. No other major American automaker of the era handed experimental powertrain technology to random families and asked them to live with it, logging thousands of miles and filling out detailed feedback forms that would feed directly into engineering decisions.
Why the Turbine Stumbled
For all its promise, the turbine engine had three persistent problems that Chrysler could not solve cheaply enough for mass production. The Smithsonian’s interpretive record for the 1964 Turbine Car identifies fuel efficiency, emissions, and acceleration lag as the primary barriers. Turbines burn fuel continuously rather than in discrete combustion events, which made them thirstier than comparable V-8s at steady highway speeds despite their theoretical efficiency advantages at certain load points. Exhaust temperatures were high enough to raise concerns about nitrogen oxide output, a problem that would only grow worse as federal emissions standards tightened through the late 1960s and 1970s and as catalytic aftertreatment for conventional engines advanced rapidly.
The acceleration lag, often called “turbine lag,” was the most noticeable flaw for everyday drivers. Unlike a piston engine, which responds almost instantly to throttle input, a turbine needs time to spool up. In stop-and-go traffic, this delay felt sluggish and unnatural, especially to drivers accustomed to the immediate torque of big-displacement Detroit V-8s. Chrysler’s engineers documented their attempts to reduce the lag through revised compressor staging, improved fuel control, and different torque converter strategies, but the fundamental physics of spinning a turbine wheel to operating speed imposed limits that no control scheme could fully overcome. The gap between what the engine could do on a test stand and what it felt like in a left-turn merge was never fully closed, and in a marketplace where subjective impressions mattered as much as objective performance, that disconnect proved critical.
Destroying the Evidence
After the consumer program ended, Chrysler made a decision that still provokes debate among automotive historians. The company destroyed almost all of the turbine cars. The official explanation centered on customs duties: because Ghia built the bodies in Italy, importing them as finished goods would have triggered tariffs that Chrysler avoided by classifying them as prototypes. Keeping them on U.S. roads permanently would have required paying those duties retroactively, along with potential liability and parts-support obligations if the cars were treated as production vehicles. Crushing the cars was cheaper, cleaner from an accounting standpoint, and consistent with industry practice for experimental fleets.
That rationale, while plausible, does not fully explain why Chrysler also abandoned the broader turbine research program by the end of the decade. The company had spent years building institutional knowledge, training specialists, and publishing peer-reviewed engineering papers, as reflected in the detailed SAE literature and the internal chronology preserved at The Henry Ford. Walking away from all of that suggests the decision was not purely about customs paperwork. A more likely reading is that Chrysler’s leadership concluded the cost of solving the efficiency, emissions, and lag problems exceeded the potential return, especially as the Big Three faced growing pressure from Washington on safety and pollution standards for conventional engines. Fixing what they already sold took priority over perfecting what they might sell someday, and as resources shifted to meeting new regulations, the turbine became an elegant but expendable sideline.
What One Survivor Tells Us
A single Chrysler Turbine Car survives in the permanent collection of the Smithsonian’s National Museum of American History, representing the most visible public reminder of the program’s ambitions and limits. The museum’s archival references and catalog notes emphasize how the vehicle straddles categories: it is both a roadworthy automobile and a rolling gas-turbine testbed, a consumer product and an engineering experiment. Visitors encounter a car that looks surprisingly conventional from a distance (two-door hardtop, familiar Detroit proportions), yet reveals its difference in the distinctive exhaust outlets, the turbine’s whine at idle, and the absence of the usual under-hood clutter of pistons, rods, and valves.
That survivor, along with the documentation preserved at institutions such as The Henry Ford and within SAE’s technical archives, complicates any simple narrative of failure. The turbine car did not die because it was a hopeless idea; it died because the economic, regulatory, and cultural conditions of the 1960s rewarded incremental refinement of the piston engine over radical change. Chrysler proved that a gas turbine could power a family car reliably enough for everyday use, and thousands of ordinary Americans briefly lived with the future in their driveways. When the company crushed most of the fleet, it closed off one possible branch of automotive evolution, leaving historians to ask not only why the turbine stumbled, but what the industry might look like today if Chrysler, or its rivals, had decided that the experiment was worth continuing.
