I just came across this interesting sidebar in the July 2014 issue of Commercial Carrier Journal where a Yokohama Tire exec breaks down fuel efficiency. For every dollar spent on fuel:
- 60 percent is wasted by engine inefficiency
- 21 percent is wasted by aerodynamic drag
o 50 percent is wasted by the drive position
o 35 percent is wasted by the trailer position
o 15 percent is wasted by steer position
- 13 percent is consumed by overcoming tire rolling resistance (average of all tread types)
- 4 percent is consumed by the load
- 2 percent is consumed by the drivetrain
Based on this info, efficient engines are by far the most important keys to fuel efficiency. What are some of the fuel economy improvements you’ve made to your engine?
