Alfa Romeo and IED collaborate on 'Gloria' concept for Geneva

The European Institute of Design (IED) in Turin will unveil its new Gloria concept, developed in collaboration with Alfa Romeo Style Center, at next month's Geneva motor show. The sports sedan concept, which is 4,200mm long, 1,920mm wide, 1,320mm high sitting on a wheelbase of 2,900mm, is previewed in this render, which shows a traditional Alfa grille that feeds into the hood's prominent V-shaped character lines. Two leather hood straps in front of the windshield are a nod to the brand's older models.

Porsche 911 (2011) the first official video of the 991

Prototypes of Porsche’s new 991-spec 911 haven’t been snapped out on test by our spies this week, so just in case you’ve been having withdrawal symptoms, Stuttgart’s most famous sports car manufacturer has released its own video of its iconic car. What does Porsche’s official video of the new 911 reveal?  Shot in South Africa during the 991’s final validation and testing phase, the video is our best look yet at the new 911 on the move. We finally get to hear the flat six engines, and get glimpses under the bonnet and inside its Panamera-inspired interior – look closely and you can spy the seven forward speeds etched onto the gearknob for the manual ‘box.  Beyond that there’s little more to see, as Porsche won’t reveal the new 911 until the 2011 Frankfurt motor show this September.
