Great to see big fast open wheeler s on the Mountain again. How many years is it that we last had anything quicker than F3s?
Hope they have the rear wishbone problem sorted because I think there are places round Mt Panorama that could cause the same sort of stresses they suffered at SMSP with potentially more serious results.
Bring it on, hopefully it is the start of a fan conversion to real racecars.

Well here is a taster OT..... from today, James Golding takes you for a flat-out tour of Mount Panorama in his Team Valvoline GRM S5000.

As to the times, already very close to breaking the 2 minute mark. Mawson was quickest on a 2:00.8702s today, just shy of the official Bathurst lap record, a 1:59.2910s, set by Christopher Mies during the 2018 Challenge Bathurst aboard an Audi R8 LMS GT3.

https://youtu.be/6A5Z9q4flm0

Edit: that is quicker than the F3 lap record by a couple of seconds give or take.... that was set by Simon Hodge in a Mygale M11-Mercedes-Benz with a 2:02.6701 back in April 2014

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.

I read somewhere that they were all using old tyres for practice. I guess they only get allowed limited new sets per meeting and they want to save the new rubber for qualy and races. Happy to be corrected on that but it seems that way from what I have read.

Having said that they looked borderline dangerous and close to failure..

I must say that I struggle to understand this. I don't think that there are currently any circuits in Australia higher than FIA grade 3 - so the described power cut should be in place at all Australian circuits.

I can't help the feeling that the adjustment should have happened much earlier but the focus on it was sharpened due to them running at Bathurst. For some time now, single-seaters have been permitted to run at Bathurst on a case-by-case basis, rather than having open slather.

Eastern Creek, Bend, Phillip Island?

Edit -- Hmm, despite the MotoGP, Phillip Island is Grade 3, however Google suggests both The Bend and Eastern Creek are Grade 2. Given what was done with Zandvoort, it doesn't seem like too much would be required to bring The Bend and Eastern Creek to Grade 1 Formula One spec, maybe just some more tarmac run-off areas?

Given they are only a handful of seconds faster than 2.0L Formula 3 cars with less than half as much power, doesn't that tell you all need to know about how little downforce S5000 cars have?

At least on those Grade 2 circuit, the S5000 should at least be as close to Formula 2 level as possible IMO. You can always put the shorter undertrays and small front wings back on for lower grade circuits.

S5000 cars are an FIA category 3 car, so have to fit within the envelope for that category - IF they were to be upgraded to Category 2 there'd need to be many more changes than you suggest, including tubs I believe although not 100% sure on that score.

Thanks CR - for some reason I thought that SMP had let the grade 2 rating lapse. So the "new" power cut for Bathurst will no doubt apply to all circuits in Oz, other than SMP, Bend and Surfers.

As S5000 are FIA Cat 3 cars though, it MAY apply everywhere they run and be applied to the cars' homologation, regardless of the circuit being used. We'll find out with time I guess.

I hope someone got a kick in the pants over that - we have seen what happens when an open wheeler goes off there, and I for one don't want to see it again. Bathurst is not a circuit for those sorts of risks. I wonder if James pitted at the paddock entrance on Mountain Straight, or cruised around to the pit entry - he must have seen the state of the tyres ...

Pretty dumb move from Macrow off the start line in race 1, swerving around and ending up taking himself and others off. The cars to do look and sound great though and the support races are very entertaining, loving the look and sound of the Historics and the Transams.
