Meet the Jaguar C-X75, a technology demonstration car that's part electric, part jet. Yep, jet. Instead of the more common reciprocating engine, engineers have instead fitted a gas turbine to help extend the otherwise pitiable range of 68 miles to a much more comforting 500+. It's a show car, it doesn't have a price tag. Still, I can't imagine it'd be a particularly quiet car.
