Tata Megapixel concept car at 2012 Geneva motor show

Remember the Tata Pixel, the posher, glitzier small car from the makers of the Nano breadcase? Now it's back for 2012, with the new Tata Megapixel concept car. It's an upgraded version of Tata's study into an urban runabout for the future, an electric supermini with a motor in each wheel.

Rolls-Royce Wraith (2013) second teaser of 600bhp coupe

This is part three of Rolls-Royce’s pre-Geneva motor show tease of its new Wraith coupe. We’ve already seen a ghostly interpretation of the Spirit of Ecstasy figurine, and a side profile shot that revealed a resemblance to a ’68 Mustang Fastback, and now Rolls has shown the rear of the Wraith, and made a few proud proclamations about just how powerful its new super-coupe will be. I can’t see much of the new Rolls-Royce Wraith… Unfortunately it’s another shadowy teaser from Rolls-Royce, in the same vein as the side profile silhouette.

Concept Car of the Week: Mazda Ibuki (2003)

With the Ibuki, Mazda designers synthesized the most successful of the first generation MX-5's iconic elements and evolved their forms to make them even more memorable and simple. To do so, they used a strong geometric theme throughout the car inside and out: LED headlamps; front air intake; tail lamps; rear view mirrors; release handles and interior details down to the pedals – every shape follow the same oval theme. Zooming out, the silhouette – as well as the top view – is also oval, making the Ibuki look more like a toy than a car, which is a real bonus for a small roadster.
