Jay Leno gives us the lowdown on his McLaren P1 (video)

Jay Leno drives his new McLaren P1 Jay Leno has no shortage of cars to play with in his collection, but if this video of Jay and his new McLaren P1 is anything to go by, the P1 is his favourite car by far (at least for now). Jay meets up with McLaren CEO Mike Flewitt at his garage and there’s plenty of chat about what makes the P1 special, and how it compares to the legendary McLaren F1 (a car Jay also owns). Then it’s time for a drive out in the P1, first with Mike Flewitt as a passenger and then with Jay on his own as he takes the P1 round the winding roads near his home, and Jay reveals that he put nearly 900 miles on the clock in the first five days he had the P1.

The Mercedes ESF 2009 Concept showcases a raft of new safety technology So Mercedes has unveiled the Mercedes ESF 2009 Concept, which is a test-bed to showcase the latest technology Mercedes sees as on its way to mainstream. Mercedes has based the ESF Concept on the latest addition to the Mercedes S-Class Range – the S400 Hybrid – and has packed it to the rafters with airbags. There’s one that pops up between front seat passengers; airbags actually in the seatbelts and one great big airbag under the car that inflates if a crash is imminent.

New Audi RS6 to get 572bhp V8

The 2013 Audi RS6 looks set to swap its V10 for the new Audi V8 with the wick turned up to 572bhp – the same as the old V10. Most of the new A6 range has now arrived in showrooms – including the S6 and Avant – but what’s still missing is a new RS6, the Audi that used to have the heart of a Lamborghini. But as we reported in April, the 2013 RS6 is well on the way but it will be losing its Lamborghini V10 with its 5.2 litres and 572bhp and will instead get the Audi/Bentley twin-turbo 4.0 litre V8.
