McLaren P1 development car in action on video

McLaren has released video of the development version of the new P1 supercar undergoing testing ahead of the production reveal at Geneva. We did think, when we got an email from McLaren entitled ‘The next steps towards production’ on the new P1, that we might get some concrete details on exactly what the P1 will offer in the way of specification and performance.

New Infiniti Q50 2.0 litre Turbo costs from £31,755 The Infiniti Q50 should be Infiniti’s best chance to convince buyers Infiniti is a viable option in the premium sector and a sensible alternative to the BMW 3 Series. That perception will be helped – a bit – by the arrival of the Infinito Q50 with another engine option, this one a 2.0 litre Turbo petrol with 211 bhp, which comes with a seven-speed automatic as standard.

Ironman Stewart retires, sells all

The off-road racing accomplishments of Ivan "Ironman" Stewart might never be matched: 82 major wins in desert racing, 17 of them in the crash-and-bang Mickey Thompson stadium series, three Baja 1000s and others too numerous to squeeze in here over a career that spanned 30 years. The thing that really sets him apart is that, while competitors shared driving duties over the long desert courses, Stewart did the vast majority of them alone, with no relief drivers--just him and the dirty, dusty desert. But even legends want to retire someday.
