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.

POTHOLES cause 'over £1 billion in damage every year'

POTHOLES are costing British drivers £1.2 billion every year due to damage to suspension, steering and wheels. This is a 16% rise in the cost of damage to cars on the UK’s roads and the weather has played a major part in the rise in the number of potholes. Councils say they don’t have the money to deal with the problem due to budget cuts and there has also been an 18% increase in the number of dangerous potholes reported during the past 12 months according to the Asphalt Industry Alliance (AIA).

2011 BMW 6-Series Convertible debuts

The 2011 BMW 6 Series Convertible - on sale March 2011 Perhaps BMW wants to grab a slice of the top-end convertible action next Spring, or maybe they just fancied turning normal model launch convention on its head by launching the soft-top first. But whatever BMW’s reasoning the fact is that we will get the 2011 BMW 6-Series Convertible in March, probably six months before the 6-Series Coupe arrives. The 2011 6-Series Convertible is, you won’t be shocked to learn, exactly what we’ve been expecting for quite some time (we even brought you the first photo of the 2011 BMW 6-Series Convertible last month) and is a topless take on the new BMW 6 Series Coupe we saw at Frankfurt back in September.
