Volkswagen XL1

This, remarkably, is the production version of the Volkswagen XL1, the most fuel-efficient production car in the world, a car we'll see in Geneva in a little over a week. Barely changed from the concept version shown at the Qatar motor show two years ago, the production XL1 is the first production result of VW's 1-liter project – to design a car that uses less than 1l/100km (282.5mpg imperial) – that started with the lozenge-shaped, tandem-seat 2003 1L and the later L1 of 2009. The XL1 actually beats that by sipping just 0.9 liters with CO2 emissions of 21g/km.
