Porsche 911 Carrera 4 (2012) first official pictures

Porsche has a new four-wheel drive - but it's not the Macan crossover, or an SUV of any description. The new-generation 911 has had the all-paw treatment, growing wider wings and fatter tyres in the process.

McLaren managing director on leave, not expected in Geneva

McLaren Automotive's U.S.-born managing director, Antony Sheriff, is expected to be absent from the launch of the P1 hypercar at Geneva next week because he is on extended leave from the company. No reason for Sheriff's absence has been given, although McLaren is at pains to point out that he is “still employed as McLaren Automotive's managing director.” Rumors were circulating about Sheriff's absence from Woking in January, but company spokesmen back then stressed that he was still employed by McLaren and would unveil the P1 at Geneva. Despite those assurances, sources had reported earlier in the year that Sheriff “hadn't been seen in his office” for some days.
