Fuel Ecomony - Towing

well as for the dealers, they have to balance performance and comfort. there is a lot of performance given up in an auto trans tuning for comfort. With an engine you are balancing performance, milage, and durability. As new materials come out that can handle higher temps, we see more fuel-efficient vehicles. for manufactures resale is the highest priority (as in when this one burns out you liked it so much you come back and a buy another) so like I said it's a huge balancing game trying to make most people like the reliability, the power and the comfort.
