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.

Are used car prices about to spiral down?

CAP – the used car price specialists – are warning that used car prices, particularly ’almost’ new car prices, are set to tumble as nearly new cars hit the market. The car market in the UK has proved amazingly resilient to the general malaise in the economy, with new car sales continuing to rise strongly and used cars seemingly immune to big depreciation drops. But CAP – who gauge used car prices for the motor trade – are warning that this could be about to change as the impact of recent trading in new cars is about to start impacting on used car prices, particularly prices for cars less than a year old.

DAB radio in cars and the digital switchover

Britain's motorists face a £1 billion+ bill to fix their car radios so they work after the digital switchover, a CAR Magazine investigation reveals. The Government plans to switch off the FM signal and move the UK's broadcasting industry to DAB digital radios - mirroring the switchover from analogue to digital televisions. The official target for the digital radio switchover is 2015, but many commentators predict that date will slip as there is a great deal of work to be done before Britain is ready.
