I think I need to explain myself a bit more, it might not be as mad as you might think. Apart from an obvious name change to something like "Aussie Supercars"....
Let's get something out the way early.... V8's are looking for a new rule set from 2017, rumours of Ford leaving after next year with Ford moving away from V8 engines and the Falcon. So I propose they join forces with DTM and SuperGT. Also you will need to ignore the previous years of racing, I for one find current DTM boring, however a new rule set we'll get new racing.
The two touring car giants have agreed a shared rule set that involves a 2.0ltr turbocharged engine that is expected to produce around 700bhp. Chassis regs have also been agreed with a shared platform across both series. Testing is expected to begin in 2016 or even late 2015.
You may or may not have noticed how this all links in yet.
Others things to remember are that the new class 1 regulations have some extrodinary manufacturers BMW, Audi, Mercesdes, Honda, Nissan and many more... imagine that lot at the Bathurst 1000!
Aussie Supercars could mange there format as they like too, race length, tyre compound, pit stops and so on.
So could Volvo and Holden be persuaded to join the party? because remember Nissan and Mercesdes are all ready there....
