Re: Audi wins at Le Mans 2006
On the pollution front, Le Mans regulations say that no car may emit visible smoke. Big problem for a 5.5 litre V12 twin turbo diesel. Audi fitted particulate filters to get around this, as well as using a new injection technology to get a cleaner, more efficient burn. The engines should be less polluting.
On the winning front, a big contributor to the Audi win was their advantage due to the regulations. They had an advantage of about 100hp over their main rivals, the Pescarolo team, who used 5 litre V10 Judd engines. The Audi cold simply pull out and overtake any other car on the track with ease.
It was eerie watching them go past, they were really quiet, you could hardly hear the engine at all. As they came towards you under braking all you could hear was brake and tyre whine. As they accellerated away all you could hear was a loud turbo whistle. To be honest if someone told me it was a new prototype electric car I could have believed it, there was just no engine noise.
I guess Audi were out to dispel some diesel myths; ie that they are slow and noisy. They seem to have done it. Give it another 10 or 15 years and I think petrol cars will be in a big minority, the wind of change in blowing. You heard it here first.
