10. Volkswagen XL1
The opposite of all the carbon creating supercars on display in Geneva is this, the Volkswagen XL1. Billed as the world’s most fuel efficient car, it’s no concept. but rather an actual vehicle that Volkswagen will sell – though apparently only 250 will be made.
Exactly how efficient is it? Try 261 mpg! How is that even possible? Well, weighing just 1,750 lbs it’s a plug-in hybrid that mates a 47 hp turbo-diesel 2-cylinder with a 27 hp electric motor. Not only can it get that amazing fuel economy, but when operated on just electricity it can travel up to 31 miles emissions free.
