GM repays Government loans – sort of

GM Loans repaid early - or are they? We can’t deny that GM are making a pretty good job of rising Phoenix-like from the ashes of their effective bankruptcy. A new focus on cars that are relevant for our times instead of a fixation with dated products and dated management has certainly helped.

Designer Interviews: Giorgetto Giugiaro

Ask any aficionado who the greatest car designer of all time is and Giorgetto Giugiaro will be the name on most lips. Responsible for more than 200 vehicles, equating to some 60-million production cars on the road as well as dozens of concepts for the world's finest car brands – not to mention cameras for Nikon, electronic organs for Bontempi and even a type of pasta – he is without equal. Born on 7 August 1938 in Garessio, northern Italy, he started his career with Fiat in the mid-1950s, aged 17.

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.
