How do you get that kind of mileage doing 40 - 45? I find that's about the worst speed for good mileage; too fast to use EV but not fast enough to get highway mileage.

On the highway (65 to 70mph) I'm usually able to get 37 to 41 mpg, depending on the terrain. My trips from Jane lew WV to Charleston average 41 when I drive, 38 when my wife drives. There are sections of that road (4 lane interstate) where I can only get 35 for several miles.

My rural milages are a lot better than my city or my Interstate milages. What I'm seeing is when my ICE is on, for the most part it is driving the wheels AND charging the battery. My battery obtains the GREEN charge a lot and when I do go down hills and across the level areas before the next hill I am either in E mode or getting 60 on the scale.

Again last night I took a trip from Jane Lew to Bridgeport (45 miles round trip) and took the back roads. No stopping, paying attention simply to the Instant FE gage, I would get up to 45 -50 miles per hour and let off the gas. I immediately reapply the throttle lightly and am able on level ground to maintain that speed with a FE in the 50 to 60 range. As I start up slopes the FE starts dropping, I may or may not lighten up on the gas. I do if it helps me stay above the 40 mark but if it starts dropping in to the 30's or 20's I use that time to pick my speed back up and let off the gas again before I crest the top of the hill. Typically I can then "glide" down the hills with the 60 reading.

It's a constant operation, but after a while you don't really have to monitor the gages constantly, you'll get the feel for it. However it does require lifting the foot often (several times per mile). Even on flat's you'll sometimes feel the ICE helping out and see the gage drop and I'll either let off to see if I can maintain reasonable speed OR again, I take that opportunity to speed up. I figure if the ICE is going to rev and get 30 mpg, I may as well accelerate and get 20 instead but in turn get my speed up so I will be ready to glide some more.

I typically can maintain the speed within a 5 miles per hour range doing this. I never even considered it until I saw someone post that they got 50 mpg. I didn't think that was possible unless you were just driving around in EV mode. I've tried it on 3 trips now ranging from 25 miles to 45 miles and was able to get 46 to 56 mpg. These are not mountains I'm climbing, but they are the hills of WV and I can't avoid them.

I'm going to Columbus (flat land) this weekend. I'll be curious to see what's possible there.
