Forget high beams -- lasers are coming

Audi has kicked off 2014 with the unveiling of an updated version of its Sport quattro concept car -- as first revealed at last year's Frankfurt motor show. Set to underpin the German carmaker's stand at the upcoming Consumer Electronics Show in Las Vegas, the latest incarnation of the bullish-looking two-door coupe showcases distinctively styled matrix LED headlamps with new laser light technology that, Audi officials suggest, will soon begin appearing on regular production models as a high-cost option. Already confirmed for the Audi R18 that will compete at the Le Mans 24-hour race later this year, the new headlamps use matrix LEDs and an aperture mask for low-beam mode.

Citroen Cactus Concept revealed

The Citroen Cactus Concept (pictured) has been revealed When the Citroen Cactus Concept was teased a week or so ago, we reckoned it looked like the first look at a simpler ‘C’ range of cars from Citroen with a touch of the urban warrior thrown in.

McLaren MP4-12C gets 616 bhp

The McLaren MP4-12C is about to get some upgrades – including an extra 25bhp – which will also be offered to existing owners free of charge. On balance, what McLaren has achieved with the MP4-12C is nothing short of remarkable. Yes, there have been a few glitches along the way, but in truth they have been little more than the sort of hiccups almost any new supercar suffers as it escapes in to the wild and has to deal with the real world and real drivers.
