Le Mans cars to get slower and quieter...
Discussion
Poo. Have a read of this
I think the 1 decibel drop for 2009 is quite a bit as the scale is logarithmic. They'll all sound like the diesels within 5 years. Time to enjoy the GT1 Corvettes while we still can!
I guess the capacity drop won't be quite so much of an issue, it'll just spur the teams on to extract more power per cc.

The new regulations: sustainable development
As was announced at Silverstone during the last weekend of the Le Mans Series (see article here) there will be a number of changes in the regulations as set by the ACO. Patrick Chaillou, the communications director of the ACO, went through them again.
- Saving of fuel: The Michelin Energy Endurance Challenge will be continued to try and make the sport as fuel efficient as possible. As the ACO: “If you want to win at Le Mans you have to make as many miles as possible, while you have to stop as less as possible, therefore consuming the least amount of fuel.”
- Biofuel: In 2008 all the participating teams in the 24 Hours will be using one sort of fuel, provided by Shell: V Power LM 24, containing 10% ethanol or V Power Diesel LM 24, the second generation BTL (Biomass-to-Liquids).
- Hybrid power: As confirmed at Silverstone the ACO will allow hybrid cars, like the Peugeot 908 HY, to race at Le Mans in 2009 outside the classification in 2009, before officially allowing them in 2010.
- Reduction of engine capacity: Like the Hybrid announcement this was also confirmed at Silverstone. From 2011 the engine capacity of the race cars will have to be reduced in order to bring down CO2 emissions and to decrease fuel consumption. LMP1 will in fact use today’s LMP2 engines, which will also mean a decrease in power and performance of the LMP1 cars.
- Pit stops: Another one we already heard at Silverstone. The number of mechanics allowed to change wheels on a car during a pit stopm will be reduced to two, this will add some time to the pit stop. The teams will also have to use a harder tyre compound in order to save tyres and therefore changes less tyres during the race.
- Noise reduction: At the moment the noise made by the cars at the Le Mans is measured at 113dB at 15 meters from the track. In the coming years the new limits will reduce noise to 112dB in 2009, 110dB in 2010 and possibly even futher in the years to come.

I knew this would be coming.
It's a travesty. Yet another one of lifes joys being slowly taken away.
As admirable as it is with Audi and Peugeot developing super quick cars running DERV, it is equally disapointing to hear the vacuum like waft as they float past.
I'm all for new technology and less poisonous gas where possible but NOT if it's at the expense of the aural delights that Motorsport has, up until now, provided for true petrol heads.
Now it seems that even if the manufacturers were clever enough to manufacture an exhaust system able to recreate a true racing sound, the new noise level laws would shut the door on that avenue.
f
king woeful.
And the most annoying part - I bet NOBODY has EVER moaned about the noise levels at LeMans. Another law to please nobody in particular but to piss off the masses.

Yep. Isnt it the final year of the GT1 corvettes anyhow??I think the 1 decibel drop for 2009 is quite a bit as the scale is logarithmic. They'll all sound like the diesels within 5 years. Time to enjoy the GT1 Corvettes while we still can!

We do moan about noise levels at LeMans. We moan extensively about the lack of noise that the Audi and Peugeot tractors produce.Aston and Corvette noise levels should be mandatory.

Well we'll all be able to sleep a little easier in the campsites;)
why would you want to sleep, there's to much to see and do, and drink! Keep the Corvettes I say. Lying in my inflatable bed, a little intoxicated last year, I reacall being able to hear the vettes doing a whole lap! Now for those people who like a bit of sweet music to lull them off to sleep, now thats a sound track!eddyendo said:

The Panoz from a while back was even better as it rocked you to sleep if you were close enough to the track to feel the ground shake as it passed!
