Aston Martin Vanquish (2012) first official pictures

Aston Martin today unveils the new, mostly carbonfibre Vanquish supercar - its 183mph range-topping V12 supercar to replace the DBS flagship. The new Aston Vanquish Mk2 lands in showrooms in spring 2013, priced at £189,995. It's a milestone car, this, for Aston; they're considering it as their anniversary present to customers as they prepare for their centenary next year.

Twizy Renault Sport F1 concept is a completely bonkers EV

Based on the  strange little Renault Twizy EV commuter golf buggy, the Twizy Renaultsport F1 concept gets a mad body kit to make it look like something out of a Star Wars film, with huge wings, side pods, a rear diffuser and a yellow paint job that evokes Renault’s sporting heritage. But it’s under the skin where the interesting stuff lurks. Renault has fitted the Twizy with an F1 inspired KERS system that fits where the back seat used to be (yes, the F1 Twizy is a toy just for one) which chucks an extra 79bhp at the Twizy’s existing electric motor when fully charged, enough to scoot the F1 Twizy to 62mph in just 6 seconds.

Land Rover Defender Harris Tweed (2012) prototype

Here's a curious mix of classic Britishness and modern modifications: a Kahn-tuned Land Rover Defender fitted with a butch bodykit, enormous multispoke wheels and knobbly tyres and - inside -tweed-trimmed bucket seats. It's like a Spitfire wearing a Damien Hurst-penned livery. This is, to give the car its full title, the Kahn Defender Concept 17 Wide Body - Harris Tweed Prototype.
