Hope not!
Long Live to Le Mans Prototype Racing!

There is enough GT cars already...

Audi has said several times it will be an open car.

Juttner clearly acknowlegdes that coupes have big aero advantage at Le Mans. I have the impression that Audi would have build a closed car for 2009-2010, if they had known earlier that the pitstop would be slowed down. The development of the R15 had progressed too far in order to make such radical change.

http://www.endurance-info.com/versio...ance-4630.html has an interview with Dr. Ullrich.

What I can tell you is that the name will be R18, R17 being the name of the future A4 DTM and R16 that of the R8 LMS. The regulation will be published tomorrow, but we already know the main points. We are just awaiting the details. I can not tell you if the car is open or closed because it is currently only in early design phase. Given the current regulations, a closed car would be much better but the decision has not yet been taken.

Audi considering closed-top car

Thursday, June 17th 2010, 08:52 GMT
Le Mans winner Audi is considering a coupe body shape for its next LMP1 car, this week's AUTOSPORT magazine reveals.
Audi Sport boss Wolfgang Ullrich has hinted that he no longer considers it viable to return to the Le Mans 24 Hours with a open-top car.
His comments suggest that the R18 built to the new-for-2011 rulebook will follow Peugeot's lead and be a coupe.
Ullrich explained that one of the advantages of an open car had been during pitstops. The change in sporting rules slowed tyre changes at the start of last season has removed that.
"If you take pure performance, it is clear that the efficiency of a closed car is much better," he said. "One of the advantages of an open car has now been removed, so we must look at both concepts.
"We pushed hard with the ACO for the rulebook to give concepts the same chance, but this does not seem to be the case."

Wont happened.
In fact both AMR and Peugeot is looking at Open cars as the increased inlet for Coupes has been removed.

I would not just to conclusions. The temperature cockpit rules will be relaxed. According to Bruno Farmin it might be possible to achieve them without air conditioning system.

With the smaller engines, the extra weight of a coupe is no longer an issue. The Lola B09/80 proves that you can build a LMP2 coupe that weighs 825 kg.

According to http://www.mulsannescorner.com/newssept09.html the better aero of a coupe is worth 5 km/h in top speed.

With less power for 2011 then aero efficiency is even more relevant so I would not be surprised to see a closed car to gain straight-line speed.

That is effective what Mike said as well

How does the fin play into the coupe v open-top decision?

I wouldn't imagine that it would. Since the regs require a certain height to the car and a roll-over hoop structure behind the driver the cars are treated the same from that point rearward. Prototypes taking flight is possible with either a closed or open car so as a safety measure it should be required regardless.

I believe Sam Collins of Racecar Engineering is often better informed: http://www.racecar-engineering.com/n...prototype.html

However, I can imagine that Ulrich Baretzky would like build an engine based on his Global Racing Engine concept. That would mean a 2.0 liter 4 cilinder TFSI, perhaps even with a VTG turbo.

IF a 2.0L happens to be used, I would imagine it with 2 VGTs.
