Jenson Button has set the unofficial lap record around the Mount Panorama circuit in Bathurst with a time below 1min 48secs in his McLaren Mercedes Formula 1 car.
After their stints in the F1 car, Button and Lowndes jumped into the Australian’s Triple Eight Racing Holden Commodore V8 Supercar.
Naturally, Lowndes had the advantage in the hardtop touring car, laying down a time of 2:11 (22 seconds adrift of his effort in the McLaren). Button was a further six seconds behind, posting a time of 2:17.
The Team Vodafone driver swap was a lead-up event to this weekend’s 2011 Australian Formula 1 Grand Prix at Albert Park in Melbourne.
