The story given by the attendents at the Chrysler Museum in Auburn Hills, MI is as follows:
When Chrysler was in financial difficulty before Lee Iacocca took over the government was checking out all their assetts and liabilities. They saw the turbine cars still intact although long since having served their purpose and basically told Chrysler they had to be sold or destroyed but could keep two as engineering training items. These 2 cars had to have their engines made inoperable and the story goes they were filled with concrete to satify the G-Men. The Ford Museum ended up with another complete car and one was sold to a private individual. The rest were dismantled, their engines taken completely apart and carefully strewn all over Chrysler's many buildings. When the gov't was satisfied and no longer was interested the Chrysler people recovered all the parts and built up 2 running engines and installed them into the 2 complete cars they had been allowed to save. According to the folks at the museum both cars still held by Chrysler are fully operable, as are all the vehicles that belong to the Chrysler Museum.
According to the museum staff 10 cars were reassembled after Chrysler emerged from their red ink. 2 remain at Chrysler, 1 at Ford, and 1 privately owned. No mention was made of the other 6. The one owned privately is complete and driveable and actually was featured on a tv car buff show a couple of years ago. I don't know if the Ford Museum car runs or is only a static display.
I've visited the mueum twice in the 6 years it has been in existence and heard more or less the same story from 2 different mueum guides.
They were demonstrated and displayed possibly using a plethora of fuels before the days of unleaded fuel, pcv valves, catalytic converters, environmental emission laws?
I remember seeing them displayed at the Ohio State Fair for a couple years in a row. Then nothing more was heard about maybe when they would ever be manufactured. They just disappeared.
Abbra cadabbra Poof! Poof!
