Chryslers Turbine Cars of the '70s ".....There were numerous functional challenges and limitations with the Turbine Cars, of which sluggish throttle response was the biggest. This is an inherent design limitation of turbines, as they need to spin up to over 40,000 rpm to develop full power. The Turbine Car had a one and a half second lag from first pressing the throttle. That could be considered dangerous; it certainly would by today’s standards. Throttle lag was noticeable at higher speeds too. Performance was reasonable, about 12 seconds 0-60, but substantially less than if a 383 V8 were under that sleek hood. One extended test produced an average fuel economy of 11.5 mpg. Not terrible, but far from good. A comparably-quick conventional car at the time would be expected to achieve about 15 mpg.
The turbine offers the potential for superb longevity, but that depends on the extent to which exotic and expensive materials are utilized. Chrysler’s own test found that its turbine had a lifespan of “up to 175k miles”. Good for the times, but not really exceptional. Chrysler’s own slant sixes would typically go that far or further. The scope of this article is not to fully explore the pros and cons of Chrysler’s turbines and their theoretical development potential. Suffice it say, the changing climate on emissions and fuel economy played their part in finally ending the turbine program during the seventies. But the biggest single hurdle was cost. In Chrysler’s own words: “the technology did not exist to produce turbine engines at a price anywhere near competitive to conventional internal combustion engines...." http://www.thetruthaboutcars.com/2009/11/the-truth-about-why-chrysler-destroyed-the-turbine-cars/ Dan Penoff wrote: > This reminds me that Kohler was doing something not long after I had left > with “capstone” turbines.
