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.

What Is It? Jaguar put an all-aluminum roof on the all-aluminum F-Type sports car and doubled the car's torsional rigidity. Since it had twice the torsional rigidity, engineers firmed up the continuously adjusting Adaptive Dynamics dampers and added stiffer springs for better handling.

NHTSA proposes rules for automakers to add sound to hybrids, EVs

Automakers would need to make hybrids and electric vehicles emit sound under rules that the National Highway Traffic Safety Administration proposed on Monday. The rules, ordered by Congress three years ago, are meant to protect pedestrians and bicyclists from vehicles that make little sound when using electric power. NHTSA says that designing the vehicles to make noise at speeds below 18 mph would prevent about 2,800 injuries over the life of each model year of vehicles.
