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.

Citroen to launch '3CV' plus DS3 cabrio, DS4 SUV, DS6

Citroen is working on a '3CV', a radical new entry-level model positioned between C1 and C3. Imagine the previous C2 pepped up by the glittery polish that's made the DS3 such a success, and you're not far off Citroen's new city car vision. Known inhouse as Citroen Trois Chevaux (3CV), it reportedly captures the spirit of the quirky Ami 6, draws on the space efficiency of the 2CV and mimics the ride comfort of the hydropneumatically sprung GS.
