The Rise and Fall of America's Jet-Powered Car
Pickens writes "The WSJ reports that the automobile designs of the 1950s and 1960s were inspired by the space race and the dawn of jet travel. But one car manufacturer, Chrysler, was bold enough to put a jet engine in an automobile that ran at an astounding 60,000 rpm on any flammable fluid including gasoline, diesel, kerosene, jet fuel, peanut oil, alcohol, tequila, or perfume. Visionary Chrysler designer George Huebner believed that there was plenty to recommend the turbine. People loved the car. In a publicity scheme to promote its 'jet' car, Chrysler commissioned Ghia to handcraft 50 identical car bodies and each car would be lent to a family for a few months and then passed on to another. Chrysler received more than 30,000 requests in 1962 to become test drivers and eventually 203 were chosen who logged more than one million miles (mostly trouble free) in the 50 Ghia prototypes. In the end Chrysler killed the turbine car after OPEC's 1973 oil embargo. 'How different would America be now if we all drove turbine-powered cars? It could have happened. But government interference, shortsighted regulators, and indifferent corporate leaders each played a role in the demise of a program that could have lessened US dependence on Middle East oil.'"
"Gas turbine" is the usual term for a turbine that drives via its shaft rather than by its exhaust.
The problem with a gas turbine is that they have rather poor efficiency. They have an excellent power-to-weight ratio (which is why they're used in aircraft, and why gas turbines are used in helicopters), but their fuel economy, even when used in an electric drive system and always running at the peak efficiency RPM, will never reach that of an average petrol engine, let alone diesel. Add that a diesel engine can run on most (if not all, when correctly filtered and if the engine is tuned for it) of the range of fuels a gas turbine can, it's the better choice for a vehicle that doesn't need to lift it's own weight except when on a gradual incline.
with fuel at less than 3 USD per gallon, why bother?
Just because you've harvested your crop and have a large current supply, doesn't mean you shouldn't plant seeds for next year.
I know it's not a car analogy, but the article is already about cars, so why not a farming analogy?
which is totally what she said
When I was in high school, my neighbor applied to 'test' of "Chrysler's turbine cars for 3 months. She had to write an essay explaining why she wanted to participate. The car was beautifully futuristic for its time and everything else seemed rather pedestrian. She took my brother and I on a ride in it just once. The experience consisted of a tour of the engine compartment, a trip to the newly-opened McDonalds, and a stop to fill up from a kerosene, gravity-fed tank that a local gas station had installed just for this Chrysler. I remember that the car sound like a household vacuum cleaner only a bit louder. You could easily have a conversation while stand next to the car. Inside the car, it was even quieter. Much of the car was fabricated from aluminum and we were warned not to put our weight on places (the tube-like console, for instance) lest we dent it. The car idled at approximately 10,000 RPM and it had a tach, which I remember watching in fascination. The turbine produce approximately 140 HP, so performance was ordinary. Our neighbor was worried about letting the car sit in one spot for too long as the exhaust was hot enough to melt asphalt. The turbine itself was wired against tampering. All the bolts had little wires threaded through the heads that were then attached to the component the bolt was used in. The car drove quite normally and the only indication it was powered by anything other the a standard IC engine was the vacuum cleaner-like sound it produced.
Travelling to other countries, particularly areas of China and India, can really drive home how low the pollution is in most parts of America. There are times that I can't see more than 100 yards down the street and this is due to the air pollution from the cars and factories.
I am going to call BS...

This car is more fuel efficient, lower emissions, faster and more powerful than anything ever produced for the commercial road.
The trick with jet engines is not to run it lower, but use the power to run an electrical engine that can be ramped up and down.

"Requiring no water-cooling system, oil or catalytic converter, it will provide vehicle weight savings of up to 15% – with a consequent reduction in fuel consumption and carbon emissions – compared to a piston engine. Further environmental benefits will be gained from its fast warm up (a few seconds, as opposed to several minutes for a conventional engine), cleaner combustion and lower manufacturing energy requirements.

"You can't make a race horse of a pig"
"No," said Samuel, "but you can make very fast pig"
Both minivans and SUVs were developed to get around the CAFE standards because there was a demand for vehicles that if they were under the CAFE standards would have made it impossible for the auto manufacturers to meet those standards
That "impossible" is not an engineering impossible, but rather a political / can't-be-bothered type of impossible.
Elsewhere in the world where CAFE-type standards were set a lot higher than the US and without the big loophole (eg. Europe, Japan) there doesn't seem to be any problem satisfying the demand for family vehicles - and median household sizes are pretty similar in EU and US (around 2.5), so family car demand will be also. I have a large 7-seater (7 adult seats not 5+2kid-sized) that you'd probably call "station wagon" or maybe "minivan". It does 50mpg, fully loaded - that's over 40mpg in US gallons.
Since that would be the large end of the station-wagons, and CAFE is average across the smaller more efficient cars as well, and CAFE standard was 27.5mpg (without using the light-truck loophole), what on earth was the problem ?
It sure wasn't the US companies being backwards in engineering knowledge - that car of mine is a Ford, and right now I could go out here and buy a Ford with better mpg & CO2 than a Prius. Not in America though, oh no, these cars are strictly not-for-US-market.
So why does Ford continue to sell the US market inefficient rebadged 1970s stuff ? Because they can, because low US CAFE targets allow them to, and because it makes more profit without needing to invest any money in modernising their US factories or technology.
Nothing to do with "impossible" and everything to do with "why bother when we can make more money using a loophole to sell old cheap inefficient stuff".
