The 111kmpl Volkswagen XL1

After working on the idea for over a decade, Volkswagen has revealed the near-production version of the XL1, a two-seat, plug-in diesel hybrid designed to be the world's most energy-efficient automobile. VW estimates the XL1 can get up to 111 kilometre per litre — although with a time to 100 kmph of 12.7 seconds, it won't get there quickly.

Volkswagen has announced the production of the world's most fuel efficient car - designed like a futuristic motor and capable of an incredible 111 kmpl.

This will give the plug-in hybrid a 0-100 kmph time of 12.2 seconds and a top speed limited to a modest 160kmph.

Overall emissions are a mere 21g/km - less than a quarter of the amount produced by the famous ultra-green Toyota Prius.

Despite weighing just 795kg, the XL1 is anything but flimsy with VW building the two-seater out of lightweight but tough carbon fibre.

It can also cover a distance of up to 50 kilometres in all-electric mode where it emits zero carbon dioxide.
