Is the hard top heavier enough to lower MPG/accleration on a JL? Specifically on a 2 door, but interested in results on the 4 doors as well.
I'm right next door to Richmond! We also make about 3 trips a year to the Smokys, but this year we haven't been down yet. But we have trips scheduled for October and December. If I could talk my husband into moving to TN, I'd be packing last nightGSM National Park. One of my favorite places on the planet. Me and my family have made 3 trips there this year. Cannot wait to make the trip in my Jeep. Have a great trip!!!! Not sure what part of Ohio you are in. I am in Southern IN. Half way between Indy and L’ville
We have been running the hard top and average between 27 and 28 mpg ( 4 cyl ,91 0ct non ethanol) Been saving the soft top for next spring . I dont expect much deviation form the 27-28. Its gonna feel like a new car when I pull that soft top out of the shed.Yeah, just normal interstate driving.
Any idea how much the soft top assembly weighs?
Yeah my initial thought, when I saw the post, was that the hard top would produce better mileage due to less frictionEven in the controlled environment of a static wind tunnel, the test results between hard and soft tops would be too small to notice any difference in fuel economy. Assuming that the hard top is heavier than the soft, its more rigid and wind resistant structure would offset that weight difference. Every movement made from the soft top, by the wind current going past it, will create more wind friction and offset its lighter weight.
Next time you're around a typical patio umbrella and its windy enough to be rocking it back and forth, close it just enough that the fabric isn't pulled tight. Note the amount of movement. Than fully open it so the fabric is pulled tight. You'll find it to have considerably less movement because the tight fabric is more resistant to the wind.
Assuming again, and further, that the hard top is lighter than the soft top, it would still require the controlled environment of a static wind tunnel to be able to measure the minute difference between the two. The only appreciable difference would be in comparing a 2 door to a 4 door, as far as the OP's initial questioning of fuel economy.Yeah my initial thought, when I saw the post, was that the hard top would produce better mileage due to less friction
