On video: the world's fastest truck

This is one lorry that you wouldn't get stuck behind on the motorway - Shockwave is the world's fastest jet-powered truck, with a top speed of almost 400mph. Based on a Peterbilt Semi, the four-ton beast generates 36,000hp and can cover quarter of a mile in six and a half seconds. Power comes from three Pratt & Whitney J34-48 jet engines, each of which produces 12,000hp.

Drivers 'not always watching road'

MOTORISTS typically have their eyes off the road for a tenth of the time they are driving, a study has shown. For 10% of their journey they are eating, reaching for the phone, texting or engaged in other activities that cause concentration to wander away from what is happening beyond the windscreen. Predictably, teenagers who had recently passed their test were most likely to crash or experience a near-miss as a result of being distracted, according to US researchers.

Citroen DS1 & new Citroen C1 2012 reveals

Auto Bild's take on the Citroen DS1 2012 looks set to be another busy year for Citroen, with the new C1 revealed at Brussels in January and a DS1 at Geneva in March. Citroen has certainly found its mojo again in the last couple of years, particularly with the very persuasive range of DS cars. And now it looks like we’re soon to get the baby of the DS range, with the debut of the Citroen DS1 at Geneva in the Spring.
