Just read confirmation that the S5000's are not running at full power this weekend. A shame that we will not see them at their best, but the ruling in an FIA one aligned to the circuit FIA grade.
They have been electronically limited to reduce power from their usual c.560bhp.
The change was in order to meet a weight/power ratio for an FIA Grade 3 circuit, as Mount Panorama is.
In standard trim, the cars have a weight/power ratio of around 1.51, well below the stipulation of “between 2 and 3 kg/hp” for ‘Category II automobiles’ in Appendix O of the International Sporting Code.
A cut of 85bhp bring the figure close to 2, maybe a bit of ballast to increase weight has been incurred to meet the 2 stipulation.
The reduction means the cars are topping out at about 280 kp instead of the original anticipated 300kph.
It seems the choice was a black white meet the figure or th category cannot run.
Very sad really, but rules are rules, and if their inclusion was conditional not much choice in the matter.
Full story.
