Audi R10s lose a heartbreaker in Mosport
First the good news for Audi Sports North America. The No. 7 R10 won the LMP1 class during last weekend's 9th Round of the American LeMans Series race at Mosport. With the win, Audi has clinched the LMP1 championship with three races left to run. Unfortunately, Audi has yet again failed to claim an outright win despite dominating the entire race ahead of those pesky LMP2 cars. The Audi driven by Alan McNish had inherited the lead late in the race when Timo Bernhard pitted his LMPS Penske Motorsports Porsche RS Spyder. Things were going well, with the McNish building a comfortable 22-second lead. Unfortunately, the R10 then experienced some kind of gearbox malfunction with ten minutes to go that left McNish with only the higher gears. Every tight corner of the track gave Bernhard another opportunity to close the gap. Bernhard caught McNish with about five minutes left to go, and went on to build a 19.575-second lead.

McNish was fortunately able to hold on to second place overall, as the another Porsche Spyder was far behind in third place. The other Audi R10 driven by Marco Werner at the end of the race came in fourth overall, and it too had a chance to win the race at Mosport overall, but unfortunately experienced a snafu in its final pit stop that kept it from exiting the pits in front of the pace car.
Everyone seems to agree that both Audi R10s were the fastest cars at Mosport last weekend, but bad luck seems to have prevented them from ending the LMP2 domination of ALMS this season.

I'm not very familiar with this form of motorsport - why are there two classes and why are they so close?

Its simple. There are two classes based on allowable power. However the more dominant the ALMS perceives you to be the more weight they add to your car. So since Audi spent their hard earned cash on developing an engine that circumvents the penalties of horsepower limits by building a diesel that will throw down more torque, ALMS has responding by throwing a temper-tantrum and limited the size of their fuel tank to less than its competitors, added weight penalties and just generally penalized innovation in the name of parity. The LMP2's can not only keep up, but beat the more powerful Audis here in America, but when they hit LeMans in France they get destroyed. All in All, ALMS was sick and tired of Audi humiliating the field with the older R8 cars (still gas powered then) so when Audi announced a faster prototype racer, ALMS started hating it.

You're oversimplifying, Joe. First off, horsepower is not limited, weight is. There are intake restrictors, but there's no absolute value for horsepower.
When the diesel formula was introduced, there were actually a number of concessions made to make diesel more competitive. Much larger allowable displacement, larger intake restrictors, and higher maximum boost pressure. Diesels also have better fuel efficiency, so with an equivalent fuel load they'd have a serious competitive advantage.
All this together led to Audi dominating with the R10 early on, so some of those concessions were re-evaluated, and the Audi was given some extra weight to make the racing more fair.
No one knew what to expect early on, so the more recent fuel load and weight penalties were only to counterbalance the unfair engine advantages the diesel formula allowed.
Your post really just made you sound like an indignant Audi fanboy.

Neither the Porsche RS Spyders or the Acuras were at Le Mans this year, which left the LMP2 category in it's usual funk. Assuming that Penske and maybe one or more of the Acura teams receive an invitation to the 2008 Le Mans race and actually show up, things could be a bit different.
I can't wait to hear that big Audi diesel at Belle Isle this weekend though. :-)

The Diesel tanks are limited to 10% less than gas cars. But Diesel fuel contains 15-18% more energy per gallon than gas, so the Diesel is still in an advantageous position.
Absolutely no weight penalties were added to the R10s by ALMS or ACO (Le Mans). In fact, the minimum weight in LMP1 was raised to benefit the R10s (this was done at inrto of the R10 by ACO). Due to the size of the engine, the R10 was hundreds of pounds over the (previous) minimum weight for the LMP1 class, so the minimum weight for the class was raised so that gas cars in the LMP1 class wouldn't have a huge weight advantage over the R10s.
What has happened more recently is that this year the ACO reduced the size of the restrictor in the LMP2 cars, this constricts the air allowed to the engine and reduces the power. ACO did this so the LMP1 cars wouldn't be rivaled by the LMP2 cars. ALMS (IMSA) didn't implement this change. The reasons for this are in both cases to ensure there is some competition for the overall win in the series.
In ACO's case, they race in Europe and Peugeot fielded a Diesel this year, and has been able to compete with Audi for the overall win. In ALMS' case, they race here in the US and Peugeot doesn't race here (since they don't sell cars here), so they needed other cars to compete with Audi and so they made sure the LMP2 cars could compete for the overall win.
After great whining by Audi (a sports car racing tradition), ALMS has made some changes middle of this season which give advantage to Audi (Diesels in general). Although of course, if your car breaks (as happened here), you're gonna lose.

You are wrong. Read literally, your comment would lead others to believe that the ACO is crippling Diesels unfairly. This is not the case. My proof? All the other LMP1 cars - every single one - finished lower than the Audi R10's.
So what does being a Diesel have to do with the R10's finishing after the Rennsport LMP2's? Nothing. Absolutely nothing.
Carlos 6:31PM (8/27/2007)
That means than these LMP2 cars are beating all the other LMP1 cars... so my point still stands. Why are the losing LMP1 cars (with no weight or fuel penalties) worse than the best LMP2 cars? Why even bother with classes if that's the case?

According to Wikipedia, LMP1s are heavier than LMP2s, but they are allowed bigger engines.
Draggy 7:35PM (8/27/2007)
LMP1 used to be called LMP900 (900kg), the LMP2 used to be called LMP875 (875kg)..
The engine displacement / forced induction specs are different for each class.
Historically, the LMP1 is for the big boys, and LMP2 are for the privateers with lower end machines.
But in the past couple years Audi has run privateers in LMP1, and the LMP2 have come a long way since the involvement of MG (yes MG) AER engine.
Now both Porsche and Acura are throwing big money at the LMP2 class.. I think it's the only way they can find their way in front of the Audi R10 for now, by being smaller and faster in another class.
The Penguin 9:43PM (8/27/2007)
@ Draggy-there was no class called LMP875, but are you just getting that confused with LMP675?

Carlos, I answered this pretty well (I put a lot of history in in either case) in a previous thread on here. Look for my name in the comments at the following story:

Kudos to the person who taped the last 5-minutes. Not really into the motorsports series... or any kind of racing, but it was fun to watch these cars pass each other in the last few laps of the race.
Is there a site that give more details of the history of the R8 and R10, their results, and other pertinent information?

Thanks for the video, Speed!
I taped the race, including going 15 mins over, but since Speed started the race 35 mins late (due to a stock car race running into this race's timeslot), I missed the last few mins of the race and I was able to see the finish here.
I can't wait for next week, as a Michigan native, it'll be great to see racing on Belle Isle. In my formative years, F1 used to race at Belle Isle, and then CART took over racing there. It'll be great to see my favorite type of racing there for the next couple years.

Joe, wow that sure is a lot of rationalization.
Fact is, they've been losing races. Fact is, when they could have won one, their powertrain broke. Quit the whinin and go home.
