Motegi endurance course/combined ring.

Quintin03 · 25 Jul 2009, 17:49 (Ref:2507891)

I have designed this long course for AsianLMS to race their top event. The race would be a 1000km, 12 or 24 hour race. This layout would be named the combined ring referring to the oval and roadcourse usualy being sepparated in a way you can use them at the same time.

It's 7.15 km/4.44 Mi. Accessing the oval you'll make a righ hairpin turn and exitting you'll first manouvre a chicane and finaly another hairpin before returning to the current roadcourse.

That is actually a very good idea!

Edits to original image in blue, for smoothness, more than anything else

Else, it's well executed.

Could anyone show about where the oval track starts to ascend before the bridges?

werner · 29 Jul 2009, 12:17 (Ref:2510705)

IIRC from Gran Turismo, the normal track goes downhill under the oval. That would make sense, since I've never seen elevations in ovals.

Aha. Thx. Sounds absolutely logical.

The question now reads as: anyone knows how steep the short connection part would be?

werner · 30 Jul 2009, 10:27 (Ref:2511532)

I don't think it will be steeper than for instance the descent at spa from les combes through the hairpin to pouhon. somewhere in the middle of the small straight to the hairpin there is a tunnel. If you walk through the tunnel from the outside of the circuit to the inside, you walk about 30 metres further, and you see a very deep valley before you, and way down below, so steep that you would need climbersgear to go there, you see the 90deg lefthander, wich is only the 2nd corner after you passed the tunnel. Here you can see what I mean:

aha. I see.

Thx.

Thanks Thatrim, that's a good edit although a chicane would be still be needed to keep the speed down. I think that your edit may even make the height differneces during turns to levels the FIA accepts. Also the track would probably bwe les than 7 km so there would be no problem.

werner · 30 Jul 2009, 16:23 (Ref:2511766)

I don't think the Le Mans-series care about FIA-regulations about the lenght of a track. Their own track offcourse is 13km, and imo long tracks are suited for their long races.

You may not have noticed but that's only because Circuit de la Sarthe already existed before the FIA made the rules even stricter (is that the word?). Also you won't see any straights or flat out sections of more than 2 km there ans I'm sure the ACO would have wanted them to stay.

werner · 31 Jul 2009, 09:41 (Ref:2512273)

That is a word, and you may be right. The Aco is, since they are French, quite stubborn, but they cannot just ignore everything the FIA says or does.

Quintin03 · 31 Jul 2009, 09:59 (Ref:2512289)

The FIA is French too. Also it would help to know that French usualy believe a professor in physics even when he's talking about history (this isn't completely true but you get the idea). Dutch like to get some numbers, facts or so before they believe someone.

werner · 31 Jul 2009, 11:43 (Ref:2512359)

I'm going to France on holiday next monday. Yeeh!

Quintin03 · 31 Jul 2009, 14:10 (Ref:2512473)

And I'm going tomorrow already.

The 10km (or is it 8km) limit/recommendation only applies to new circuits.

Correct but it's 7km actualy and it's only a recommendation. That's what I've read in an official FIA PDF file.

That's correct.

Purist · 13 Aug 2009, 13:59 (Ref:2520834)

They prefer it that way, because beyond 7km, official procedures elsewhere call for the use of two pace cars for full course cautions on circuits of more than 7km.

Still, is it really safer to decelerate from 215mph three times as opposed to from 255mph just once (referring to Le Mans)?

You're second sentence doesn't make much sense after what you've said in the first but I get the point and you're totaly right.

Is this thread realy done because there are only two versions of the circuit, are we all sure it's done?

Purist · 14 Aug 2009, 13:52 (Ref:2521368)

Unless I missed something, the pace car procedures are NOT in FIA Appendix O, which is where you find the recommended limit of 7km on international-standard circuits.

Sorry if I crossed wires jumping straight in on the 2km limit on straights. My second comment was referring to the Mulsanne.
