Mistaken ideas about how a diesel engine works

I think the big thing that some of us are saying is too stop with the HP wars, hold them where they are at and work on mileage instead. I see no reason why the new crop of diesels can't get at least 3+ more MPG! If they they put the effort into that instead of power lots more people would sit up and take notice.

Years ago they said a gas V-8 would never get better than 20 mpg. Guess what mid 20's is what they are now getting!
