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.

Think City EV Cup Edition (2010) first official pictures

Manufacturers have been trying to make their racers more economical for some time now; Audi and Peugeot have produced diesel Le Mans winners and CAR reviewed the Porsche GT3 R Hybrid in the June 2010 issue, but this the most recent fully electric offering from Norwegian company Think.   Think has followed the traditional road-racer conversion for this one-off prototype, by stripping out most of the interior and space for the passenger, using Perspex instead of glass in the windows, installing a solitary lightweight bucket seat and lowering the centre of gravity. The company claims the diet reduces the Think's weight by nearly 70kg; that's the same saving as a Lamborghini Gallardo Superlegerra, remember.
