I read their column about a month ago, and in it, someone had asked why fuel economy hasn't gone up too much over the past 20 years. Tom and Ray said that it was because automakers have focused more on horsepower/performance than MPG's. I forget exactly how they put it. An example they used was the Honda Accord. A mid 80's Accord made about 80-
90 HP and got about 30MPG. Today's Accord gets about 35MPG but puts out 160HP, double what it put our 20 years before. And Tom and Ray pointed out that most people don't need 160HP in their car, and that most people only use about half that power. They also said that most people would probably prefer a 2006 Accord that puts out 100HP and gets 50-60mpg rather than a 160HP car getting 35 mpg. I know I would. So in effect, instead of engineering/tuning cars for MPG's, they've instead been tuned for maximum HP/performance.Why can't automakers develop 2 lines of engines? Super efficient 80-
100hp units to go into the Taurus, Accord, Camry, Malibu, etc. and cause the cars to be able to get 50-60mpg. And then a line of perforamce engines for these cars that put out 160hp and get 30mpg. Now, if you look at cars, there isn't much difference in the performance between the base 4 bangers and the optional V6 engines. The V6 will put out maybe 20-30HP more in power, and MPG's are usually about the same in the inline 4 and the V6.I, for one, would rather cut my gas bill in half and have a 90hp engine than have a 160hp engine.
