LA Auto Show Design Challenge entries unveiled

The 2013 Los Angeles Auto Show Design Challenge entries have been revealed a few days before the show is set to open. As in previous years, several of the major players in the automotive design world are participating and automakers and design studios such as BMW DesignworksUSA, Subaru, Mazda, and China's SAIC and Changfeng will be exhibiting concept art. The theme of this year's design challenge is called "Biomimicry & Mobility 2025: Nature's Answer to Human Challenges.” With nature coming to be seen as one of the best R&D labs for design, and with biological knowledge doubling every five years, design studios were challenged to design vehicles that use biomimicry to increase the efficiency of mobility itself.

BMW Z4 GT3 (2010) first official pictures

Z4 M fans look away now – this is an officially sanctioned BMW Z-car with the 4.0-litre V8 engine from an M3. This is the BMW Z4 GT3. It isn’t, at least not for the road – the Bavarian company maintains that its sDrive 35iS Z4 with a 335bhp twin-turbo straight is as far as it’ll go.

Lamborghini Aventador Roadster sold out for the next year

It seems that the newly launched Lamborghini Aventador LP700-4 Roadster is already sold out until the middle of 2014. That North American East Coast outing comes just a few months after Lamborghini revealed its open-topped Aventador at the Los Angeles Auto Show in November with the same 6.5 litre V12 engine as its tin-topped sibling and a 0-62mph of a scant 3.0 seconds. At a UK price expected to be just the right side of £300k you might think, especially in these financially constrained times, Lamborghini might struggle to find buyers for its ultimate toupee wrecker.
