Summernats 26 has broken the Guinness World Record for the most simultaneous burnouts in front of thousands of fans at Canberra's showgrounds.
Minutes after the attempt Chris Sheedy from Guinness World Records told the 10,000 plus crowd at Canberra's EPIC showgrounds that exactly 69 cars had managed to complete the 30 second burnout required.
The novelty of the number was celebrated by Summernats punters.
'It's particularly an Australian kind of record,' Mr Sheedy told reporters.
'If someone broke it elsewhere in the world, I think Australians would be offended.'
His greatest concern about the record had been that the cars were placed so close together.
'When cars are burning out, we know that they do tend to slide sideways,' he said.
'But they did an incredible job and not even one of them slid.'
It was one of those events that was 'incredibly hard' to organise, which deterred people from breaking the record, he added.
The burnout blanketed the entire area with white and pink smoke, caused by the complete shredding of tyres that cost about $500 to $600 each.
For about 15 seconds during the burnout observers were unable to see past the person standing next to them, and after the event firefighters had to put out one or two small rubber fires on the purposely built burnout pad.
Summernats co-owner Andy Lopez said the attempt had taken months to organise and more than 200 staff were involved in pulling the event together on the day.
'We had to do 50 cars at least to break the world record, and in typical Summernats fashion we smashed it with 69,' he said.
'Actually being able to get 69 of the cars that are prepared to smash some tyres just for the sake of making a record is a once in a lifetime thing.
'I heard about 30 tyres blow during it - it's a bit of a rubber bath out here.'
Summernats continues until Sunday.
