I think the 80% number is outdated (although most of the energy is still wasted)

F1 engines achieve a peak thermal efficiency above 50 percent, significantly higher than a modern passenger car's 35 percent thermal efficiency - https://www.motor1.com/news/655596/video-how-f1-engines-make-1000hp/

So more like 65% goes out the tailpipe...

If your rolling coal, you are literally pumping unused diesel fuel out the car. You're efficiency is absolute dog shit.
