Food for thought but with today's technology one would thing we would be a lot farther along with fuel economy than we are. Case in point. My 2002 Silverado with a 5.3 4x4 extended cab gets on average 16mpg, If I want I can get 19 but that is keeping it at 55mph and taking it easy. Spring forward to todays new GM vehicles with direct injection and 8sp transmissions and they are only getting 20mpg. To me that isn't much of an advancement in economy. Come to think of it, my dad's 1977 Chevy 1500 stepside with a three on the tree and a 350ci engine got 15mpg. Funny, a three speed and a carborated engine getting what modern tech is getting today.
Another point was when I had my 91 VW Jetta diesel, I was getting 50mpg out of it as well as when I had my parents old 1979 Rabbit diesel it got 50mpg. Granted I know that emissions have a major play in what diesels get now but seems to me one would thing we would be getting the same mileage on an average mpg on new diesels more so than not. My Cruze diesel gets consistent 45mpg but I have been able to get 50mpg if I really hyper-mile.
Just seems odd that we are no farther along than we are when it comes to economy.
