Don't sleep on the Highway fuel economy!
I just came back from a weekend at the in-laws. My wife drove most of the way home so we won't talk about the overall trip average....
BUT On the way up there I calculated my average FE to be 37MPG (NAV had me closer to 40). It was a 153 Mile trip in 50 degree weather on 99% highway driving. I managed to do a little bit of distant truck drafting on the trip. I drove at a nearly constant 65 MPH on the Turnpike and 50-60 on the "Parkways". I started with no charge and had almost half a charge left when I pulled in to their driveway. (For those familiar, it was on the NJ turnpike and the Belt Parkway/Southern State Parkway out on Long Island) Anyone who claims "Hybrids are no good on the highway" I beg to differ. |

I'm with you Tim! At a constant 60 MPH I get about 42 MPG with Denver's thinner air ( less air drag ). So I think 37 MPG for you is very comparable.

Re: Don't sleep on the Highway fuel economy!
That's phenomenal Tim! I had a similiar road trip for Thanksgiving and averaged about 29. My wife wouldn't let me draft. :(

Re: Don't sleep on the Highway fuel economy!
That's excellent Tim...Good to know a regular driver can get that MPG! (although, since you admitted to drafting...you've just crossed over, I think ;)
On the I-5 in California, I cant keep the 65pmh speed...I'll get run over by a semi doing 70, or a hummer doing 80 (and 12mpg I would bet). And, yeah, my wife wouldnt let me draft either. |

Re: Don't sleep on the Highway fuel economy!
Majority of my driving is highway. My daily commute is approximately 30 miles round trip of divided hiway through open badland/prairie and make weekly trips of about 100 roundtrip miles to the nearest city center. I was just beginning to master the hiway when winter set in; the warm up required in winter sucks. I was averaging around 33-35mpg but this brought down due to wifey's short trips on my days off to her work in town (< 1mile no EV). I have no doubt that I will be able to improve that this year...I think if I am diligent and not running late for work too often I'll be up around the 40mpg mark soon myself. And I plan to pick up a HV battery warmer in the fall from a place called Big R's (?) in Montana...it's actually designed for dog beds but is the perfect size.
I would encourage anyone hesitant to draft to at least try following semi's at a safe 5sec or so distance. There is still considerable wind break at this distance and I notice quite a difference in lower rpms (2-300 or so). There also isn't much risk of getting rocks and crap thrown up into your windshield. The best advantage I find is having the semi in front of me keeps people who pass me from cutting me off and throwing rocks, etc. HTH |
Re: Don't sleep on the Highway fuel economy!
For the record, it was DISTANT drafting. Especially with my wife and son in the car I'm not about to take any unneccessary risks of things flying through the windshield like a tire tread. You can even get the benefits if there is a car between you and the truck.

(For those familiar, it was on the NJ turnpike and the Belt Parkway/Southern State Parkway out on Long Island) Did you use the cruse control? I did. Possibly, that was the mistake? I did notice that on the upgrades (hills), the cruise control wanted to rev the ICE up to over 3K RPM attempting to maintain an exact 65 MPH speed. I was wondering if that sucked up a lot of gas? |
Re: Don't sleep on the Highway fuel economy!
Congratulations Tim - 37mpg on a highway trip is great! And in the Mariner, which is heavier (I think) than our FEH FWD's:)
