Wild thing: Audi A1 clubsport quattro unveiled

Audi has created a 496-hp version of the A1 small car to celebrate the 30th anniversary of an Austrian festival for Audi, Seat, Skoda and Volkswagen fans. Called the A1 clubsport quattro, the one-off show car gains a heavy dose of rally-inspired styling that is said to preview the appearance of a hot new all-wheel-drive S1 quattro model being developed by Audi as a rival to the likes of the Renault Clio Sport. At the heart of the hatchback is a heavily modified version of Audi's turbocharged 2.5-liter, five-cylinder powerplant shoehorned transversely into the A1's compact engine bay.

Bugatti Veyron Grand Sport Vitesse world speed record: Video

We hoped that tease might be for something really interesting and new – perhaps the much rumoured 1600bhp Veyron or even the Galibier –  but it was simply a new world record for an open-topped production car. Impressive, of course, but just more of what we expect from Bugatti, rather than something new and innovative. The new world record for the Vitesse was set at the VW facility at Ehra-Lessien where Chinese driver Anthony Liu took the Veyron Grand Sport Vitesse to 254mph, creating a new world record for an open-topped production car and, more importantly for Bugatti, an excuse to produce a limited run of the Veyron Grand Sport Vitesse WRC Edition with a black and orange paint job for €1.99 million each.

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.
