Charlie, that is what bugs me is up until the last three or four years we were not seeing the fuel mileage gains I would expect. You look at almost every car line and not until 2013-2014 did we see major improvements of 5% to 10% increases in fuel mileage, excluding hybrids. My 87 Volvo was rated pretty close to my 97. Even by 2014 there was an increase according to the EPA rating system of only one to three mpg highway for a similar model S80 Volvo. It wasn't until 2015 that Volvo finally got on board with the fuel mileage bug where the numbers jumped up seven mpg, and for the 2016 eight mpg over the 2014 S80. Look at GM, Ford, Chrysler, Mercedes, BMW, VW, Toyota, Mazda, Nissan, even Honda and fuel mileage increases in their automobile lines, excluding Hybrids, you see almost minimal fuel mileage increases, until the last three or four years.
