Official: Renault & Caterham to build Alpine sports cars

Renault has confirmed it is to partner with Caterham to build a range of Alpine sports cars in Dieppe from 2015. The partnership between Renault and Caterham is a logical extension of their F1 partnership but now, with the joint venture to produce their own sports cars, goes much deeper than the almost badge-engineering Williams Renaults. A new company - Société des Automobiles Alpine Caterham – will be jointly owned by Caterham and Renault and will develop models in small and large volumes to be marketed as both Renault Alpine and Caterham, and will be built in Renault’s Dieppe factory that currently churns out Renaultsport models for the road and track, and is the historical home of Alpine.

Subaru Cosworth Impreza STI CS400 (2010) revealed

This is the new Cosworth Impreza STI CS400, a limited edition Subaru tuned and tweaked by one of F1’s most famous names. It costs nearly £50k, and will hit 62mph in 3.7 seconds. Almost – there’s 400PS, so 395bhp in our language; Cosworth removes the 2.5-litre flat-four from the STI and sets about seriously overhauling it.

Preview: Porsche Panamera

After what has already been the most drawn-out model introduction ever (the initial Porsche sketches of the new model having been revealed in 2005), Porsche has finally released the first official rendering of its forthcoming Panamera sedan, set to be launched in 2009. Though the plan view doesn't show much of the new Porsche's design, the company says the features will 'include a wide and low body offering dynamic proportions and muscular design'. But while the grand tourer will have a 'compact overall look', the interior space is claimed to offer a brand-new experience of roominess, with two single seats and generous headroom at the rear allowing adults to sit in comfort.
