Pagani Huayra sets Top Gear lap record and places marker for McLaren P1

The Pagani Huyra set a stunning record time on the Top Gear track last week and in the process laid down a marker for the new McLaren P1. The return of Top Gear at the weekend for Series 19 saw Richard Hammond get to grips with the Pagani Huayra – successor to his beloved Zonda – and after a thoroughly positive test drive Hammond handed over to the Stig to take the Huayra round the Top Gear track.
