Renault Twin-Z concept (2013) first official pictures

This is the Renault Twin-Z concept (say it 'Twin-Zee'). Although it packs the usual concept car madness of suicide doors, a pared-back cabin and LEDs everywhere, it actually previews the look – and drivetrain – of the next Renault Twingo. The big news is that it'll be rear-engined, rear-drive, and offer an electric option for less money than the £13k Renault Zoe EV.

This week in 1994: We meet the Rolls-Royce Flying Spur

Rolls-Royce introduced the Flying Spur in 1994 as the fastest vehicle the brand had ever made. Its top speed was 140 mph and it flew to 60 mph in seven seconds flat with the help of the 6.75-liter turbocharged V8 under the hood. The only catch?

Toyota Camatte 57s concept

You may remember last year we reported the unveiling of a customizable, modular little concept car called the Toyota Camatte at the Tokyo Toy Show. This year Toyota has returned with an updated version called the Camatte 57s with more scope for families to personalize their space-framed little machines with a total of 57 external panels (as its name suggests) as well as the removal of the roof which apparently "adds to the fun factor and allows everyone on board to enjoy the colorful exterior they have created". Like last year's car the driving position can accommodate both adults and children with gown-ups sat in the right rear seat able to intervene should the infant pilots go astray.
