VW Nils concept – it’s another posh city go-kart

Volkswagen NILS Concept We’ve been trying to think where this little fad for electric go-karts for commuters started. We think it might have been the Renault Twizy, but we’ve a feeling there’s something earlier. But never mind, the latest is from VW – the Volkswagen NILS.

Design Review: Bertone Birusa concept

The new Birusa concept unveiled today shows Bertone returning to what they do best - a flamboyant showcar giving us a vision of how the high performance GT car (front engine, rear drive, two seats) could evolve stylistically in the near future. Based on a BMW Z8 aluminium chassis lengthened by 300mm, it's a refreshing piece of exuberance by the Italian company and a celebration of what they achieved in the 1960s and 70s. The wedge-shaped profile is characterised by a classic Bertone device - a dihedral-shaped side window with an undercut lower glass section, as featured on showcars such as the Boomerang and Carrabo.

New 2015 Mazda2 arrives

This is the new 2015 Mazda2 (Demio) The new Mazda2 was all but revealed at the Geneva Motor Show in March in the guise of the Mazda Hazumi Concept, but now the real new Mazda2 has arrived, or at least it has in Japan. But Mazda are captioning the photos – which are clearly of the Demio – as the Mazda2, so we can be pretty sure not much is going to change when the Demio gets the Mazda2 badge in the UK and Europe. That means the same Kodo design language Mazda has introduced across its range recently with a shield grill flowing in to the headlights, big wheel arches and horizontal lights at the back – all very much like the Hazumi.
