Making of the Porsche Panamera Sport Turismo (video)

Porsche has released a video chronicling the development of the Panamera Sport Turismo as the first model extension of the Panamera. Earlier this month we had a video from Porsche of the Panamera Sport Turismo on the move with comments and insights on the design process, and now we get a more detailed look at the development and thinking behind the transition from ugly duckling Panamera to stunningly good looking Panamera Sport Turismo. Porsche don’t want to call the Sport Turismo a Station Wagon, but that is effectively what the Sport Turismo is (and it can’t be a true Shooting Brake with four doors).

'Defective tyre' prosecutions top 10,000

MORE THAN 170 motorists were convicted every week in 2012 for driving on defective or even dangerous tyres. The figures, obtained by tyre safety charity TyreSafe as part of its efforts to improve awareness during Tyre Safety Month, show that 10,228 drivers were taken to court over their tyres. As rain becomes a more regular fixture for most motorists up and down the country, following an unusually dry summer, tyre tread depth and pressure become even more important.

McLaren SLR Edition revealed

McLaren SLR Edition A year ago – almost to the day – we reported that the very last McLaren SLR had rolled off the production line (well, production floor is more like it at McLaren) and that McLaren and Mercedes were going their own ways – McLaren with the McLaren MP4-12C and Mercedes with the Mercedes SLS AMG. The swansong for the SLR was the SLR Stirling Moss, an SLR dressed up like a silver arrow car from the 1930s, without a roof and only a vestigial windscreen. Or at least we we believed the Stirling Moss was the last SLR.
