ACO regulations for 2006 released
www.lemans.org for more information
Looks like its got 'user friendly' for next year, the drivers get air conditioning and the spectators get quieter cars (for 2007). |

I also see that Shell will become the official control fuel supplier of the Le Mans 24 Hours from next season.

To compensate for the weight of the air conditioning system in the closed cars, ALL cars will run 25kg heavier next year, so LMP1 is now 925kg. All cars will get slightly bigger restrcitors to compensate for the extra weight. Cars will have to comply with 113db or less in 2007. I believe they run to this level at Portland, the turbo LMPs are much quieter than 110db, so that gives you some gauge at how loud the cars will be. BTW, how many LMP1/LMP900s were actually down to 900Kgs? |

I have to say, the air conditioning 'rule' came out of left field, didn't it? Are they going to bring back spare tires and FIA suitcases next?

...na, just enough room for a large bottle of Crown Royal feeding an IV between the shift lever and the parking brake. Said "Whiskey" must not exceed 39 degrees Fahrenheit. All competitors must use standard readily available whiskey located in the Crown Royal "Funnel Zone" Special Rerserve (TM) tent.
*This amendment will be in place for ten years pending litigation. |

Just been looking at the new refuelling regs for diesel as opposed to petrol. It seems the flow restrictor allowed on the diesel rig has a maximum inside diameter of 38mm whereas the petrol (gasoline) flow restrictor has a narrower inside diameter of 33mm.
This implys (to people like me who have little or no technical understanding) that not only will the diesel powered P1's refuel less often, but when they do refuel, will be able to do so more quickly which will further disadvantage their petrol powered adversaries! Why the discrepancy? Am I right to assume that diesel is a more viscous liquid with a slower flow rate, the larger diameter flow restrictor simply compensating for its different properties? |

One question from me, are we still looking at the prototypes being quicker at le mans and in lmes than the last couple of years taking into consideration the weight increase, and the power loss from the A/C. I know there is a slight increase in power, but will that really offset these increases?

I would think the 2006 LMP1s will be significantly quicker than the 2005 hybrid cars.
As has been shown most cars were over 900kg to start with, and the A/C is only used on closed cars. We have seen how much quicker the P2 Lola and Porsche have been compared to the Hybrid P2 Courage, so I would expect a similar jump in performance for full P1s over the 2005 hybrid cars. Factor in the increased development factory P1s will have over the likes of the Hybrid Pescarolo, and I would think they will be 2+ seconds a lap quicker at Le Mans. Consider a 5 year old 950kg, 560bhp+ Audi R8 has been a contender for most of the LMES season, now image what a state of the art 925kg, 650bhp+ R10 will be capable of. |

The TVR was 200 deg inside during Le Mans this year... it's was pretty warm even in Istanbul in the rain! Seems like a sensible rule but a lot can be done by buying good breathable suits (the stretchy nomex) and refridgerating balaclavas... would've thought that was a better way of helping the drivers out without adding weight to the cars... look at the difference between Corvette and Aston at Le Mans: Corvette bought the good stretchy nomex suits, Aston insisted on free suits from a "suitable partner" (anyone who'd give them free kit)... the Corvette drivers were fine, the Aston boys had fire extinguishers emptied on them to try and keep them cool in the nice "shiny" suits they were wearing.
Some of the difference was down to the cars, but a huge amount is due to the kit: Stand 21 have done some serious research on this with the French army: http://www.stand21.fr/heatstress/heatstressc2c.htm it's worth a read to understand why guys are fainting in cockpits and why most of the teams in the know at Le Mans race who are buying their kit rather than being given it are in the Stand 21 stretchy suits! Cheers Rick Yes I do wear their kit! And yes it's saved me a couple of times. But i'm not sponsored by them. The last guy who got free kit from them was Senna! If you're better than Senna than you might be eligible for a free set of gloves... but then I guess Rolex don't give away many watches either... unless u win Daytona! |

I don't want quieter cars, ear plugs only cost £1. Part of the attraction is the great sound these cars create as they zoom past. Seems a pretty Wimpy regulation to me.

Isn't a simple weight solution just to take the windshields off the cars?

Creating a temperare difference of 30/40 degrees with an outside temperature of 25 to 35 degrees? Cooling it down from 60/70 to 30 degrees in car that continues to develop heating through the "shield" between the engine and the cockpit, pedals, exhaust beneath the floor...........
That must be real technical challenge to develop. Almost impossible ![]() What happens with a car when the airco breaks down? Black flag? Cause it's illegal to the new rules? If not........create a "malfunction" on the airco for the last two hours of the race. Saves a lot a fuel.........you could skip that last splash and dash ![]() How are they going to control the temperatures? What about the condensed water on the windows of the car? ![]() |
