In my head, diesels should be great for racing. They make great torque and great HP. Why aren’t they used for racing?

They don’t make good HP compared to their gasoline counterparts though; gasoline burns much quicker than diesel does which causes the redline of diesel engines to be much lower. Audi had to spend shitloads of R&D money in making a diesel engine that could operate at high RPMs. Audi has since switched to hybrid drive trains which offer many of the same advantages (fuel economy, actually instant torque) and can operate at high RPMs.
