VW Golf R Cabriolet (2013) first official pictures

Volkswagen has officially revealed the Mk6 Golf's swansong: the production-ready Golf R Cabriolet. First seen at the 2011's Worthersee enthusiast show, the new Golf R Cabriolet packs the same 266bhp engine as its hard-top sister, but loses its all-wheel drive underpinnings. It's now a front-driver, like a regular Golf GTI.

Zaha Hadid Z-car concept

Zaha Hadid is an Iraq-born and London-based architect, who became the first female recipient of the Pritzker Architecture Prize in 2004. Her ambitious buildings have earned her much acclaim, and having designed the latest BMW factory, Hadid has now turned her sights on cars with the unveiling of the Z-car concept. Not to be confused with the similarly titled Nissan/Datsun, Hadid?s Z-car is a small plastic-bodied monocoque with a prominent lifting door.

2009 Mercedes-Benz S Class

The Mercedes S Class has long been at the forefront of car technology. You can bet your boots that what we see on any new S Class will be where mainstream makers go in years to come. The S Class was first with things like inertia reel belts and air-bags, and the 2009 Mercedes S Class (perhaps we should call it the 2010 Mercedes S Class in deference to our US friends) – although an update rather than new model – follows this tradition.
