2011 Armor All Bathurst 12 Hour

The 2011 Armor All Bathurst 12 Hour was an endurance race for FIA GT3 cars, Australian GT Championship cars, Group 3E Series Production Cars and other invited vehicles.^[1] The event, which was staged at the Mount Panorama Circuit, Bathurst, New South Wales, Australia on 6 February 2011, was the ninth running of the Bathurst 12 Hour, and the fifth since the race was revived in 2007.

The race saw GT cars return to long distance racing at Mount Panorama for the first time since the 2003 Bathurst 24 Hour. The addition of the faster GT3 entries saw the leading cars smash the previous distance record by 29 laps. Unfortunately it also saw many of the Class D and E cars not compete due to being reduced from outright contenders in previous races to class contenders for 2011. One of the reason's for including the GT cars was an attempt to not only increase manufacturer involvement in the race but to also raise the international profile of the event and attract the top FIA GT3 teams.

The race was won by Audi's official factory supported team Audi Sport which was run by Audi's Le Mans 24 Hour team, Joest Racing, under the banners of "Audi Australia" for car #7 and "Audi Top Service" for car #8. Running a pair of Audi R8 LMS GT3s, the team of Marc Basseng, Christopher Mies and Darryl O'Young (#8) lead home teammates Mark Eddy, Craig Lowndes and Warren Luff (#7) in a 1-2 finish, the cars crossing the line only 0.7141 seconds apart in a true racing finish. Lowndes fastest race lap of 2:09.0861 also set a new GT lap record for Mt Panorama, cutting a second from the time of 2:10.0277 set 16 months earlier by Tony Quinn driving an Aston Martin DBRS9. Lowndes time came within 0.6210 of his Team Vodafone teammate Jamie Whincup's outright lap record of 2:08.4651 set in a Ford BF Falcon V8 Supercar in 2007. The Joest Racing R8's finished one lap in front of the VIP Pet Foods Racing Porsche 997 GT3 Cup R of Craig Baird and father and son pairing Tony and Klark Quinn.

The race was run under international endurance rules meaning that all cars compulsory pit stops were each to be no less than 90 seconds in duration. The Class A cars had to make 12 compulsory stops with no less than 10 laps between each stop while Class B cars only had to make 9 compulsory stops.
