Lamborghini Aventador J at 2012 Geneva motor show

There maybe other Italian sports car manufacturers looking to hog the limelight at the 2012 Geneva motor show (and Ferrari and its 730bhp F12 is one of them) but Lamborghini will vie for attention with the Aventador J. A two-seat, open top speedster based on the Aventador LP700-4, it has some intriguing bits of carbonfibre tech and highly individual design. Named 'J' after the FIA’s Appendix J that governs the tech spec of race cars in certain classes, it’s proper bedroom wall material – but little boys and girls are unlikely to ever see it on the road as it’s a one-off and will go to a lucky owner after its appearance at Geneva.

Google continues autonomous car tests [w/video]

Google is leading the charge towards the production of a fully autonomous car, releasing a video earlier this week of the car being tested on a programmed route. Steve Mahan, who is 95 per cent blind, successfully tested the car with Google engineers and a member of the local police close at hand should something go awry. Google kitted out a Toyota Prius with its software, taking the shape of a spinning cylinder on the car's roof, which senses traffic or activity close to the car and automatically adapts to its situation.

Rinspeed BamBoo concept (2011) at 2011 Geneva motor show

There’s no doubt the folk at Rinspeed like to think outside the box when it comes to concept cars – and the new BamBoo will evoke plenty of admiration when it makes its debut at the Geneva motor show in March 2011. Not for Swiss car visionary Frank Rinderknecht it isn't. He says every name has a meaning and in this case it's because many of the interior features are made from actual bamboo fibres.
