Top car tech from the British International Motor Show

When large groups of cars are gathered together to be drooled over it means one of two things: you're a teenager with a pimped Vauxhall Nova flaunting an ASBO in a McDonalds car park, or there's a motor show going on. Luckily, at London's ExCel Centre this week it's the latter and yesterday we popped down for a nose around.We pushed our way to the front of a huge crowd for a glimpse of what's been grabbing all the headlines so far; it's Lotus' first new car in 13 years – the Evora (pictured). So what have they been doing all this time? Crafting a lovely looking new motor to take aim at the Porsche Cayman by the looks of it. With a 3.5 litre Toyota engine producing 280bhp, it should be able to hit 60mph in around five seconds. We want.Vauxhall's highly anticipated Mondeo rival, the Insignia, had our tech senses tingling with its sign recognition camera. Mounted at the top of the windscreen it scans the road ahead 30 times every second looking for changes in speed limit or no-overtaking signs. If it spots something likely to cause you to come a cropper it'll flash a warning up on the dashboard. There's also a Lane Departure Warning system that reacts to sudden changes in your driving style to warn you if you're heading off track, plus auto adaptive lights that alter beam shape depending on ambient light and road conditions. It's a long way from our knackered old Fiesta, that's for sure. We'd be lucky if that'll even hit 30mph at all.Elsewhere, in the Electric Vehicle Village, Tesla showed off its Roadster electric coupe, while NICE, Smart and Think all had eco-friendly jam jars of their own. What with those and the Lightning there really was a big green halo over parts of the Motor Show this year – although perhaps still slightly obscured by the petrol fumes. Be sure to check out the Stuff.tv vidcast later in the week for some exclusive video of those cars and more.And don't forget us Stuffers are also gearing up to take over the ExCel from the 31 October until the 2 Nov for this year's Stuff Live show.
