cthib10 should be qualifying in the top 10 on the grid
LMP1 Question

I was just looking at the New Aston Martin AMR-One and couldn't help but wonder why any team building a brand new car would even bother building a petrol over a diesel? It's been quite clear for some time now the advantages of a diesel. I know the regulations are changing but I really don't expect much to change so it seems like a waste of money on the part of Aston Martin.

Aston doesn't sell diesel cars, so there is no marketing point in building such a car. I suppose it is their hope that the ACO will eliminate the Diesel advantage, or G H-C will just "politic" to get things changed.

Aston hemmed and hawed about their LMP entry because of that disparity, and it's my understanding that the ACO have finally adjusted the engine regulations such that a gas engine now has a chance. We'll see. Aston seems confident. Frankly I don't think they'd be here if they didn't from a regulatory standpoint. Now it's up to them to execute to meet that expectation. Not sure they have with the AMR-One. It will be interesting to see what the I6 has...

In theory, a petrol car should be lighter, as the engine is simpler with petrol. Take out turbos, and intercoolers, etc, and more weight saved.

Somehow, no-one ever managed this trick since R10TDi arrived.

Hopefully, despite the turbo, AMR have turned the trick?

Because there's a minimum weight and even the diesels managed to get down to it eventually?

You should still have an advantage as far as balancing is concerend with more "free" weight to move around your car and consequently a lower center of gravity... but appearantly that advantage was so far not big enough to make a difference.

I still think a proper factory petrol P1 would have been a lot closer to the diesels. Look at the pace of the Acura in P2 compared with the rest, and that's probably had a fraction of the money that Peugeot has.

It's written in the regs there can be no more than 2% (4 secs at Le Mans) difference in pace between different technologies but not sure how they take into account other variables.

Is that a new reg? Because the ACO have manifestly failed with any attempt at equivalence since the disels raised their heads......

New for 2011 and will be looked at a few times per season, no excuses not to have equal competition.

I really hope that is the case but it will be hard to believe it until I actually see it.

Well fingers crossed that e do have some chance of seeing a petrol car competing with the oil burners. and an aston would be icing on the cake.

In an interview at the Aston LMP launch, GHC said that he thinks he won't need the balancing corrections because he would be surprised to find the Aston that far behind the diesels. Now of course GHC is known for posturing....

The ACO mandates a data acquisition box on all cars too. Hell they could even fit one of those high-tech gizmos that measure horsepower in realtime within the driveline, at least on some diesels - Audi and F1 teams have tested with that.

The sad thing is that our best hope for a reversal of things has NEVER turned a wheel as of now, something like 100 days before the race. Next year maybe, but I'm sure many would be interested to know what are the real numbers the ACO is looking at. The Pescarolo calculations inferred from plain trackside timing from before he got a Peugeot were already quite interesting.

George's tone did not suggest in any way that he was posturing!
