Diesel Racing

And not just any racing, either. Le Mans racing.

Audi has a V-12 diesel that is 5.5 liters, and exceeds 650 hp with 812 lb.-ft of torque. All this with regulation twin turbos at 43 psi, and regulated intake diameter. (In other words, this thing could rock a few more steeds with larger, higher-pressure turbos.)

This redlines around 5,000 rpm, which is just slightly lower than gasoline powered hp equivalents which redline in the 8,000 to 12,000 rpm range (I don't remember for this class of cars, the more exact numbers).

I wonder what it sounds like. I also wonder what kind of transmission configuration they had to do to to get it to speed.

Well, one may never know. Here is the link to the original article that I found on Jalopalink.
