Porsche 911 50 Years Edition (2013) at Frankfurt motor show

Here’s the inevitable special edition 911 to celebrate Porsche’s rear-engined icon’s half-century. The 911 50 Years Edition uses the Carrera 4’s 44mm-wider-than-standard body, rear-wheel drive and the Carrera S’s 395bhp 3.8-litre flat-six engine in either seven-speed manual or PDK form. In a nod to the 911’s birth year, only 1963 examples will be produced, each costing a cool £92,587 – a £10k premium over the Carrera S.

New Renault Clio arrives

The new Renault Clio has been revealed ahead of a debut at the Paris Motor Show with a new look and five doors. Although it’s still based on the underpinnings of the current Clio, the new Renault Clio is a lot more than a facelift of the current car. For a start, it comes as a five door only, with the back door handles hidden so it looks like a three door, and gets a bold new style that’s been influenced by the Renault DeZir Concept with a new corporate nose featuring a big front grill and Renault badge and big, swoopy crease lines down the doors.
