That trackside camera captured the sound prefectly. That's exactly how it sounds for spectators. Incredible.
-
The diesel stormed the racing world!
-
Proves that races arent being won by sound and just brute power :) I really love the low deep roaring of this diesel!
-
I was at Sebring and these really surprised me the first couple of times they went by. they sneek up on u when u least expect it!
-
today i've have seen this car in barcelona, it's a flying carpet, absolutely quiet!!
-
I saw this car also at Sebring in March. This car actually sounds like an electric car. The most exciting part was the Peugote TDI was just as quiet but faster than the Audi.
-
I completely agree. I have some guys I sim race with who HATE diesels only cause they make no sound ;) I love them, They are better in every way just like you said. Audi TDI forever! <3
-
It doesn't make much noise, but the noise that is coming out of there sounds real good for a diesel engine.
-
Indeed. The Audi is a twin turbo 5.5L. Gasoline engines with turbos cannot exceed 4.0L in LMP1 class. Normally aspirated they are allowed 6L I think. Rotaries aren't banned either. Last two years Mazda has had a tri-rotor Renesis in a Courage for the LMP2 class. The rules, however, are against the rotary. Not terribly competitive. They make the horsepower, but it takes way too many revs to get there. The power curve is just not at all workable to be competitive.
-
hahaha those turbos had me giggling like a child!!
-
Hey thanks for the clip
-
The turbo is part of the reason(its one of the reasons CART/Champ Car held onto turbos - slightly muffled exhaust note was good when racing on city streets). But its also that Audi WANTED it to be quieter. One of the points of the R10 is to prove to the public that diesel is good. By making it quiet they appeal to the people who think diesel is painfully loud. By making it FAST they appeal to the performance-minded who thinks diesel is crap.
-
wow it's sooo smooth!
-
That whistling was definitely the air passing over the car - it was not a turbo whistle. I've worked with enough turbos to be able to tell that clearly.
-
yeah, i was there too , you could probably stand next to the track and the thing would pass by you without even knowing
-
Actually, the reason you can't see the brake glow is because the R10 uses special brake "drums" and covers to help cool the brakes (which are disc brakes, BTW) Oh, and sorry for marking your post as spam. I meant to hit the "reply" button, but clicked the "mark as spam" one... sorry...
-
Hehe.. quiet but not completly silent. I can't wait to hear what the peugeot sounds like as a comparison.
-
Diesel motors smoke because not all of the fuel is burnt on combustion. The turbos get more air into the engine, and the car's electronic control module controls the fuel entering for a more precise fuel burn.
-
twin-turbo, with mufflers and particulate traps.

Would be cool to see Mazda's improvements in rotaries duking it out against the diesels in Lemans.
