6hrs of São Paulo

[Michelin]

Any of you guys are going to the brazilian round of the FIA WEC this weekend?

 

[Mac K]

Will they have live streams up? I'd like to watch a bit of it..

I don't really know... and I'll be at the track watching.

 

[Jav]

I'm guessing the WEC stream with Radio LM as ussual...?

 

[hawkeye122]

Or, you know...


Speed 2.

Gosh, it's so much fun saying that!

Audi will have their stream, and you can boot up the RLM stream to go with it. Best of Both worlds.

Someday I'll get arround calling freaking Brighthouse about it!

When, they were at Silverstone I didn't see the race on SPEED 2.

www.fiawec.com has the live stream, and so does their channel on www.dailymotion.com!

 

[Shinshiki]

I wonder if Toyota can get the win this weekend? The Audi's seemed to have better fuel economy at Silverstone.

 

[MarcoM]

Audi will win again. But that should no-one stop from going there. I would if I had the chance.

Audi should win again on balance of probability, but we don't know what updates Toyota will bring to the race.

Don't forget, the Toyota team is well used to bringing new updates on-stream quickly. They have a staggering facility in Germany, far more advanced than what Audi have.

 

[MarcoM]

Well I hope you're right. It would certainly be nice to see Toyota breach the hegomony of Audi.

It was on there when I looked. But the highlights didnt stay up for very long.

Toyota will be down on power with the high altitude in Sao Paulo, but with that they may be able to use less fuel than usual. Depends on their engine mapping. I think Toyota can pull out a win. The FIA have released the 'Hybrid zones' for Interlagos http://private.fia.com/web/fia-public.nsf/vchp/430/$FILE/12-D-0016-LMP1-Braking%20_zones_SAO_PAULO.pdf turns 1, 4, 8, 10 and 12. All but one of these are slower corners. Audi will not be able to release their hybrid nearly as soon as Toyota, because 4 out of the 5 zones are under the speed that Audi is allowed to use it's hybrid @120kph.

 

[Rods_Ramone]

I will be there. Unfortunately, I won't be able to go to the WEC qualifying, on Friday, but Saturday all day long.
Looking in the schedule, there will be lots and lots of gentleman's races, buy anyway, Fittipaldi is doing a good job promoting the event.

Sao Paulo is only 800 m above sea level, can this altitude affects so much the Toyota's engine performance?

 

[freshseth83]

Yes, it can affect their performance. HP Loss = (elevation x 0.03 x horsepower @ sea level)/1000. So Interlagos is about 2600ft above sea level- so multiply 2600 x .03 x 550hp(?) then divide by 1000, and you're left with about a 43hp loss at that altitude.

That's a lot of loss, according with what you say. How could imagine that top of engine technology can be hardly affected by something not so significant.

 

[Michelin]

Good thing they didn't put the horrendorous (not sure if I wrote that right ) chicane in main straight (Subida do Café) they usually put when local racing series race at Interlagos.

THe RLM commentary is usually part of the video on Audi.tv

 

[Tired Tyres]

No ISDN line means they are struggling to do commentary.

[R0ssingt0n]

I read that yesterday, hopefully their commentary will go ahead as usual. Watching sportscars without RLM doesn't feel right!

 

[Hun200kmh]

15 minutes to free practise 1 👍

 

[Sier_Pinski]

Toyota will be down on power with the high altitude in Sao Paulo, but with that they may be able to use less fuel than usual.

And Audi and the rest of the field as well? All cars there are powered by a fuel-driven engine which requires air intake. Unless Audi's diesel car somehow requires less air then the others?

 

[Shinshiki]

Audi was fastest in free practice 1 and Toyota was fastest in free practice 2.

The natural aspirated petrol Toyota suffers more hp loss at altitude than the high compression turbo diesel unit in the Audi. A turbo usually negates most of the power loss at altitude that NA engines suffer from.

That's why we use turbocharged engines in aviation! No penalty from high altitude!

[freshseth83]

Didn't slow Toyota any did it? They may be using a richer fuel mixture to compensate though which will hinder fuel economy. Not saying that's 100%.

If that's the truth, then Audi will probably beat them on fuel economy again. Just as they did at Silverstone.

 

[freshseth83]

Well qualifying will be in about 2 hours time. Practice 3 saw the two Audis go into the 1:22's for the fastest times so far. I wonder if they'll get to the 1:21's in qualifying. The last time LMP's raced at Interlagos the Peugeot 908 set a 1:18.xx in qualifying. Race fast lap record is in the 1:21s, so I think that may be broken this weekend.
