Autoweek looks at Ford Mustangs that never were

When a car has been around for nearly 50 years, like the Ford Mustang, it is bound to go through many generational styling changes. In most cases, it will also be the subject of several design studies and concepts that never make it to the auto show stage.

Porsche Panamera (2009): first official photos

By Tim Pollard First Official Pictures 24 November 2008 09:00 Today's launch of the new Porsche Panamera is a timely reminder that Porsche is no stranger to controversy. It is happiest pursuing mechanical layouts others deem impossible, turning gamekeeper and buying Volkswagen outright, and laughing in the face of cynics who deplore Porsche-badged off-roaders.

Lamborghini Aventador

A clear evolution of both the Murcielago and the Reventon, the Aventador dissapointed and wowed in equal measure at its unveiling. Showcasing Lamborghini's newfound love for carbon fiber as well as an exhaustive list of new technologies for their road cars – such as a pushrod suspension – the Aventador certainly has a supercar-style spec sheet. The V12 engine used in the Aventador is also all-new and when combined with the lightweight carbon monocoque chassis is claimed to provide blistering performance, albeit in an unrevolutionary body.  More images of the Aventador, as well as the opinion of Chris Bangle, can be found through the links: Photo Gallery: Lamborghini Aventador Video: Chris Bangle on Supercars
