Design Contest: Terra Prix 2085

Local Motors is back once again with another design competition. Unlike previous contests that aim to produce cars through open source design, the Terra Prix 2085 contest is set firmly in the future. As the name would suggest, the concept is based around the idea of future motorsport: an around the world race taking in all continents and every variety of terrain.

Mercedes S65 AMG (2013) first official pictures

By Ollie Kew First Official Pictures 08 November 2013 08:01 Bring on the ‘too much is never enough’ comments: this is the new Mercedes S65 AMG – the top dog of the S-class range. Set to be more than twice as expensive as an entry-level S350 BlueTec, which starts at £62k, the S65 AMG borrows its powerplant from the SL65 AMG, and comes close to embarrassing the SLS supercar in a drag race. Whereas the new S63 makes do with a piffling 5.5-litre biturbo V8 developing 577bhp, the S65 squeezes in a twin-blown V12 good for 621bhp – that’s only one horse fewer than the Mercedes SLS Black Series manages.

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.
