***Official Le Mans 24 Hours Thread***

Oh no same for me, I will be in the middle of a med cruise :( last years was just amazing. I will just see how much I can record on the sky+ box.

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 cant wait for this thing to appear on track! I think its amazing! Obviously it has the potential to be completely rubbish, or just not make it at all, but if it does, then its going to be great.

They have dared to break all the 'rules' on race car design. I hope it works for them.
 
Paddocktalk are suggesting that the Audi hybrid is to be unveiled on 29th February before the Audi Annual Press Conference 2012...

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.

Its a ground effect car. It uses enormous venturi tunnels to suck it to the road so it doesn't need big wings.

That was the whole idea behind the original IndyCar concept. Using ground effect means air over the top of the car is less important, so turbulent air is less of a problem, and therefore following closely behind someone is less of an issue.
 
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...

Eww, not a fan of that paint job.

And how is it Flywheel KERS? Unless the ACO have changed the rules and we missed it? With the speed at which the Audi's disintergrated against the barriers last year, I wouldn't want a lump of metal spinning at 40,000rpm sat next to me...
 
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.

 
Flywheel KERS is used in place of a battery. Energy is gained from wheel/axle motors that turns to electricity which is used to spin a motor that spins the flywheel. When engaged the flywheel spins the motor which becomes a generator which generated electicity which powers the wheel/axle mounted motors and powers the wheels.

Sounds like a fairly traditional flywheel KERS to me.
