Video: Michael Mauer on the 991-series Porsche 911

Porsche has released a video featuring its Design Director, Michael Mauer, explaining how he and his team went about redesigning the 911, an ‘automotive, engineering icon' as he describes it. "What we as designers are striving to above all is to optimize the width to height ratio with the result that although the 911's width has not increased, the front axle area has become wider, and we've managed to make the roof a bit lower," Mauer explains via a rather dramatic-sounding voiceover.

MG TF – finally built at Longbridge. Plus mystery MG

By Tim Pollard First Official Pictures 02 June 2008 12:18 After a series of twists, turns, delays and wildly ambitious claims more akin to a Miss Marple whodunnit, MG has finally built its first TFs at the Longbridge plant in the West Midlands. We've seen the first TF LE500 models at Longbridge and we hear they will be in dealers soon, priced at around £16,000.  What's changed since the last 2005 cars? These early pre-prototypes look virtually unchanged, but now come with a body-coloured hard-top, leather seats, air-con and improved interior plastics as standard.The cars pictured here have the new standard-fit glass rear screen, wind deflector, 16in alloys in shadow chrome or satin-black finish and the new piano black interior trim and revised dials.
