our ausi V8 Supercars run on E85 they started using it for the 09 season and it didn't seem to affect the cars at all.
it was well and truly tested at mount panorama Bathurst this year, where they drove there cars around the tarck for 161 laps
Mount Panorama Motor Racing Circuit is 6.213 kilometres in length and 874 metres above sea level.
this is a cool video of a flying lap of the track back in 2003, new lap record that they still can't beat to this day.
