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.

Vettel takes pole in Brazilian Grand Prix at rain-soaked Interlagos

Vettel takes pole in Brazilian Grand Prix at rain-soaked Interlagos The weather may have been horrible – with rain lashing the Interlagos track – and Sebastian Vettel may already have taken the F1 driver’s title for 2013, but the weather and the already won title made no difference. Sebastian Vettel has taken pole position for Red Bull at the Brazilian Grand Prix. The heavy rain at Interlagos managed to delay Q3, but Vettel was as impressive as he has been for the rest of the season to continue the run of Red Bull poles, followed by Nico Rosberg in the Mercedes in second and Fernando Alonso took third place, his equal best starting place this season.

Pierre Authier: I'm not moving to Opel/Vauxhall

As the ongoing General Motors designer saga continues, the latest Opel/Vauxhall Vice President of Design elect, Pierre Authier has taken his name off the shortlist for the Rüsselsheim. Car Design News had received information from a reliable source within PSA about Authier's supposed move, however we have since spoken to Pierre, who was keen to put the record straight: “I read the flattering article on my recruitment as VP of Design for Opel/Vuaxhall, but this information is false,” he told CDN. “I am really enjoying my position at Peugeot and with the 208 family team that has made such incredible work.” The search for the missing piece in the GM puzzle continues.
