***2012 Le Mans 24 Hours Thread***

Well folks, it's just a few months to 24 heures du mans at Le Sarthe and I can't find a thread so we should have one :p

Last year's race was utterly amazing - a battle between the lead Audi and Peugeot right up to the end and I was glued to the coverage with Radio Le Mans cranked up. This year it won't be quite as exciting because Peugeot have pulled out, allegedly for financial reasons. But it appears that Pescarolo will be using Peugeot parts but not the whole car, because Peugeot have refused to let the cars be used. Call me cynical, but it's probably so they don't lose face if they go on to lose all their races...

What we do have this year is a hybrid car in the form of the Toyota TS030, which appears to be able to use the pit lane on its motors and the engine fires up as it leaves. It's packing a lot of energy recovery from braking and I'm looking forward to seeing what it'll do in the safety car scenarios. It'll also be interesting to see how far it can drive on the motors alone. It's quite common for cars to run out of fuel halfway round the track, and the circuit is a total of 8 miles long, so it'll be interesting to see if the car can make it back from say Arnage corner on its motors.

There are a LOT of 458 Ferarris running in the GT class this year. Years ago the GT class was dominated by Porsches and Ferraris. Corvette and Aston literally crushed the opposition and the reliability of the Ferraris really showed up as a flaw. They all but dropped out a couple of years ago and even the Italians were campaigning Corvettes. The Porsches also dwindled in numbers for a couple of years which is interesting, because they used to be bulletproof reliable and hence the amateur teams with the lower budgets used to favour them. Sadly, no BMW M3 or Ford GTs in the GT classes this year.

There is also the fabled Delta Wing team campaigning alternative technology. It's a streamliner that looks like it belongs on the salt but the team are convinced it'll run at Le Mans. I can't see how it'll stick to the track, personally, but bring on the alternative technology. Two years ago Porsche, Ferrari and a number of other supercar manufacturers were demonstrating their hybrid and alternative technology cars. It was pretty cool seeing prototype Ferraris loaded with electric motors and batteries up next to their screaming petrol motors, I can tell you!

Video: here's a bit of TS030 pit action. Sounds amazing. Listen for the engine to kick in up at the top end...

I think it is. The only snag to that report is I'm pretty sure the Le Mans regulations state that any energy recovery has to be electrical and no flywheel systems are allowed.

This is what's published on Wikipedia about it:

Wikipedia said:
From 2009 onwards the Le Mans regulations new from the ACO allow hybrid vehicles to be entered, with either KERS or TERS (Kinetic/Thermal Energy Recovery System) setups, however the only energy storage allowed will be electrical (i.e. batteries), seemingly ruling out any flywheel-based energy recovery systems. Cars equipped with KERS systems were allowed to race in 2009 with specific classification rules. From 2010 they will be able to compete for points and the championship.
 
will be a shame if the porsche dull-fest is simply replaced by a 458 tiny-penis-dull-fest.
I know where you're coming from, but at Le Mans it's not like the high-buck GT races you see with all the rich boys and their toys. These are actual racing teams who pick their cars on a budget and who want to finish the race. The fact that the Italians were campaigning Corvettes says to me that they aren't proud and they're picking cars with their heads, not their hearts. I've yet to see Ferrari reliability in the GT classes at Le Mans though, so in my mind these 458s are either significantly cheaper, significantly faster or significantly more reliable than the Porsches :D
 
Trying to piece together what Pescarolo's entries are actually made up of. Pescarolo and Deltawing will be using AMR-1 chassis at some point. Looks like the chassis must be modular, because the picture in this link shows the Deltawing next to what appears to be just the driver cell:

So the question is, what are Pescarolo ACTUALLY debuting? There’s also been talk about Peugeot parts, Judd engines and a car built by Morgan. The entry list looks like three different cars: 2 different Aston-based and one Dome, with Judd engines.

There were Ferraris in GT1 and they used to lead the class, but Corvette came in, walked all over them and highlighted their reliability issues, closely followed by Aston Martin. Likewise, there have been Corvettes and Astons in GT2, so they would have been competing directly.
 
Paddocktalk are suggesting that the Audi hybrid is to be unveiled on 29th February before the Audi Annual Press Conference 2012...

I'm no car designer but surely there's no way this thing can go round corners? Looks like it would be better suited to boneville lol.

Edit: more technical info, 27.5/72.5 weight distribution :eek::confused::

I can't see how it's going to work, personally. Le Mans LMP cars rely heavily on downforce for grip and there is little to no provision for any on this car. Kudos for them trying though, and I'm very excited about seeing it. It uses the cockpit compartment out of the old Aston AMR car. That said, it is very very light, very streamlined and a lot wider at the back than it was first depicted.

I saw the air dams at the back. Perhaps they're aiming for all the forces at the back, with all the weight set back there too; the idea being the front wheels in a super-light narrow front chassis are just in place to point the car around?
 
Moley has exposed the new Aston GTE in the other thread. Official launch of the Audi hybrid was yesterday. They've plastered the Quattro name on it and it looks like it is a flywheel energy recovery after all. Should be an interesting race against the battery/supercapacitor system in the Toyota.

Looking forward to see how they fare at Spa...

It doesn't look like a direct mechanical connection, so I wonder if that's what the ACO rules mean by a flywheel KERS. Looking at the albeit deliberately vague pictures and details Audi have released, it looks like a motor between the front wheels and a flexible connection to another box. I guess this could contain another motor that spins up a flywheel instead of charging a battery. I don't actually know how F1 type flywheel KERS works so I can't comment otherwise.

 
So going on the entry list:

Car 15, the OAK Pescarolo 01-Judd, is the OAK racing team with a Pescarolo 01 car and a Judd engine. OAK were campaigning the Gulf-liveried Astons last year?

Car 16, the Pescarolo 03-Judd, is the Pescarolo team in the AMR-One tub with a Judd engine.

Car 17, the Dome S102.5-Judd, is the Pescarolo team in an updated Dome S102 with a Judd engine.

Have I got that right?
 
I see Peugeot have unveiled a diesel hybrid road car. This is interesting and I think it has to be linked to their Le Mans legacy. I wonder if they actually dropped out for sales reasons? There was quite a risk to lose the race to Audi and it might have hurt their sales? Interesting that they have launched the car before Le Mans and Audi haven't.

But of course I could be reading way too much into this :p
 
Here's a bit more info on the TS030 smash:

http://www.topgear.com/my/?p=5702

Test driver Nicholas Lapierre was apparently driving in heavy rain to test the car’s wet handling conditions, when one of the electronic units let in water and caused the accident. Technical director Pascal Vasselon said the team is working on sealing the electronics, but expressed concern they’ve lost all of April and the chance to test at Spa ahead of the Le Mans 24hrs.
