Next year's V8 Supercar championship could be broken up in to two phases with a mid-season break from late July to mid-September, the sport's executive chairman Tony Cochrane said on Saturday.
The proposal was one of several made by Cochrane at the Triple Crown event in Darwin.
Former drivers' champion Mark Skaife will head a committee aimed at enticing new manufacturers into the sport, while 14 cost reduction initiatives have been proposed to keep current teams in business.
Cochrane said the changes are needed to keep the sport viable in the current economic climate.
"Despite the global financial situation, we still remain highly sought out as a championship," Cochrane said.
"Certainly the possibility exists for us to expand either next year or the year after to 16 events.
"One of the problems you've got in this country is because of football codes, and not many countries have three major football codes and we do, because of that trying to program time to satisfy everybody in that mid-July to mid-September period is very, very difficult."
Skaife and his team will be charged with sorting out the specifications for the so-called "car of the future", with the only requirements for that vehicle to be that it must run off a V8 engine and have a top end price of $250,000.
Currently, the cars used in the championship have a top-end cost of around $500,000 to $600,000 per vehicle.
Cochrane confirmed the new car could bring in manufacturers other than Ford or Holden for the championship when it is introduced in 2011-12.
"I know Mark has already spoken to some manufacturers and I know that he intends to have follow-up meetings with some, I know he intends to speak to additional ones on top of that," he said.
"We very much want to maintain a very healthy, a good relationship, going forward with both Holden and with the Ford Motor Company of Australia and we want to maintain them in what will be the car of the future new-look championship from 2012.
"Both of those manufacturers are saying to us now, they would encourage and would like to see other manufacturers involved." Cochrane also revealed 14 proposed cost reduction methods which could save the teams millions of dollars in expenditure, a move he says is vital.
"As each item is approved by the board, it will then be added to the rule book as a matter of urgency because I am determined, and I have a mandate to deliver on real cost reductions to every team in this championship," he said.
"We have been criticised in the past for how slowly we have moved on these issues - I intend to change that perception." Following last week's resignation of chief executive Cameron Levick, Cochrane also hit out at suggestions the sport was struggling.
"Let me assure everyone in the wider motorsport community, V8 Supercars has an extremely strong management team, a strong championship going forward, a strong financial position, in fact the envy of many sports," he said.
"There are no leadership concerns whatsoever in V8 Supercars Australia."
