Porsche Macan caught on video

The Porsche Macan – a Porsche Cayenne on a boil wash – has been spied out testing and caught on video. We’ve seen spy photos of the Porsche Macan before – Porsche’s take on the Audi Q5 – and they look more like a cut down Cayenne being used as a mule for the Macan’s underpinnings than an actual Macan. But it seems that the shots so far are actually the Macan as it’s heading for production, which means Porsche has, perhaps unsurprisingly, chosen the 911 school of car design as its inspiration for the Macan and just stuck a Cayenne on a boil wash.

How Mercedes sees into the future

Mercedes' crystal ball is named Alexander Mankowsky. At 56, he's dressed for CES in khaki trousers and a leather vest, with thin glasses perched on a round face; his frizzy white hair resembles what Einstein's would if he were caught in a wind tunnel. He might be a long-distant uncle, or he might be Doc Brown, fresh from the DeLorean.

Beating the motoring bullies

A NEW INITIATIVE has been launched to help women protect themselves from aggressive drivers and potential dangers if their car breaks down. The Women in Gear scheme includes an evening workshop course to teach basic maintenance and useful get-you-home tips. These are aimed at helping women sort out minor problems with their car rather than having to wait at the roadside for help.
