Chrysler Turbine car
If you want to lose an afternoon down an internet wormhole (and honestly, why else are you reading TopGear.com) then pop ‘Chrysler turbine car’ into your chosen search engine and marvel at the results. The Chrysler ‘Typhoon’, as the concept was known, was far from the only gas turbine car (Rover tried it in the UK, and Abarth built one for racing) but the Chrysler is the coolest because the whole car was themed around the idea of the jet age, from the turbine-look headlight surrounds and ‘transmission tunnel’ to the outrageous exhausts.
Only 55 were built for a (surprisingly successful) test programme, and nine survive today. It would run on petrol, tequila or even perfume, apparently. The engine idled at 22,000rpm, but barely made any noise when cruising. We’d josh about it ‘never taking off’, but we’re above that.
