In a major change to the format, 1986 was the first time in the history of Hardies Heroes that drivers only had one lap to set a time. From 1978–1985, drivers had two laps in which to set a time. •
Peter Brock had qualified the #05
Holden Dealer Team Commodore 2nd fastest with a 2:18.10 but the car was heavily damaged in a crash in Fridays's qualifying by
Allan Moffat and was not repaired in time for Hardies Heroes and was subsequently withdrawn from the session by the team. Race organisers the Australian Racing Drivers Club (ARDC) then elevated the
Graeme Crosby Commodore into the Top 10 Runoff in its place. Brock had also qualified the HDT's #3 car with a time of 2:17.7 (good enough for 2nd behind Grice), but the race rules prevented car swapping in qualifying and his time only served to qualify him in car #3 for the race and not Hardie's Heroes. It was the first time Brock would not appear in the Saturday morning runoff since its inception in
1978, leaving
Dick Johnson as the only driver to have done so.*
Allan Grice became the first
Group A driver to lap the 6.172 km (3.835 mi) circuit at over with a 2:16.16 lap in Friday qualifying in his
Holden VK Commodore SS Group A. Grice had also been the first to lap the track at over 100 mph in a
Group C touring car in
1982 driving a
VH Commodore. He had also set his qualifying time running on
Dunlop Tyres and not the
Yokohama's he was required by contract to run when the television cameras were running in the runoff.* Through their mutual
Philip Morris cigarette sponsorship, the
Peter Jackson Nissan team had tyre warmers for their cars flown out from the
McLaren Formula One team in England to cope with the cold conditions, the first time the technology had been used in Australian touring car racing. Despite this and the fact that he was the only driver to improve on his qualifying time, pole winner
Gary Scott believed the tyres on the
Nissan Skyline RS DR30 were still not up to full operating temperature. This was put down to the fact that after team finally got the blankets working,
Ch.7 had the Top 10 cars line up for 45 minutes on pit straight to film part of their TV package shown around the country later in the afternoon during which time the tyres cooled back down.*
Roberto Ravaglia had been officially second fastest in qualifying behind Grice with a time of 2:18.19, aided by a tow from a couple of Commodore's down Conrod Straight. Without the tow, Ravaglia fell to 9th in the runoff. Ravaglia and his co-driver
Dieter Quester weren't originally scheduled to drive the
BMW 635 CSi. Originally advertised to be driving were
BMW factory
Formula One drivers
Riccardo Patrese and
Gerhard Berger.* The 1986 version of Hardie's Heroes saw four new drivers contesting the Saturday morning runoff for pole position. Pole winner Scott,
John Bowe (5th),
Graeme Crosby (7th), and
Brad Jones (10th). Scott (
1979 and 1982) and Bowe (
1985) had previously been in cars that had qualified for the runoff, but it was their respective co-drivers who had set the times.*
Brad Jones, whose
Mitsubishi Starion had been the fastest car on Conrod Straight during qualifying at , was forced by officials to run on smaller width wheels during the runoff after checks revealed the car was using wider tyres than was allowed. Jones aborted his lap in Hardies Heroes at the top of the mountain after the smaller wheels caused the car to handle badly. ==Official results==
