I did some cost comparison between EV charging vs gas at 2.76 at Sam's. It is the same at work .15/Kh vs .51 cheaper at home .12/Kh. It is looking like it doesn't make cense to charge on a trip unless you can get the cost down to .12/Kh.

I charged up over night and it showed 100% charged this morning, ScanGaugeII had 90% and when it showed 0% charge SGII showed 24%. This morning it showed a range of 40 miles and after 7 mile trip it showed 34 miles. I plugged in the Level 1 charger and the ranged dropped to 31 miles and it showed 2 hours to get back to 100%. After charging it showed 37 mi. range, an hour and a half later when I went to lunch it showed 41 mi. I'm guessing it's a temp thing, the HVB heats up when charging and cools off after an hour or too making the range go higher.

For some reason I don't get the feeling of speed that I did in the CMAX, probably from sitting up higher. I was watching Regen and SOC doesn't go up very fast.

I'm going to hold off on doing any Mods like Grill and Wheel Covers, Gas Pods, tire pressure, rear wheel well covers ect. until I get a good feel and understanding of the car.

Only have Level 1. I mean visually out of the window I can't tell how fast I'm going yet, car has very good acceleration, 0-30 mph if you mash the accelerator the ICE will come on with the electric motors.

This morning with 100% charge it showed a range of 46 miles and it went up to 47 miles when going some down hill and ended up with 39 mi. range to go when I got to work. When I turned car back on it dropped to 35 miles range. I went to lunch and back, 8 miles + the 7 miles to work = 15 mi. and add that to the 32 mi. range left it looks like I can get 47 mi. on this charge. This is with speeds of 35 to 55 mph. I think EPA range per charge is 37 mi. so that works out to 10 miles farther without any Mods or Hypermiling. I'm using coasting in Neutral going downhill though, I can't help myself.:) If I used the same plan tomorrow I would end the day with 42 miles and 5 mi. left on the range. Maybe by the end of next week I will have my Mods ready. One of the easy things to do is raise tire pressure from 34 to Max pressure of 44 psi. I have my Gas Pods from CMAX they're magnetic, easy to install. I'm thinking I will be able to improve range by atleast 3 miles, maybe 5 mi.

I checked this morning and the All Electric mode didn't change. Last night when I plugged it in the display showed 100% charge range at 50 mi., but this morning it showed 45 mi. and when it got to work it had 38 mi., 7 mi. to work. My garage doesn't cool down very well and the HVB temp was 84.5*F and when I got to work it was 86*F.

Specs say that the HVB has 14.4 kw capacity , the SGII says at 0 there is 24% left and fully charged 91% which means EV is only using 9.5 kw (91%-24%=67%x14.4 kw), the numbers don't seem to be coming out right. Last night when I got home the Display showed 4.5 mi./kw and range of 50 miles which = 11.1 kw capacity. This morning at 100% charge the range dropped down to 45 mi. and divide that by 11.1 kw=4.05 mi./kw. On the Electric Efficiency display it says "Average 4.5 mi/kWh or Estimated range on next full charge is 50.2 mi".

Decided to go ahead and install Gas Pods and raise tire pressure to 44 psi., they were 32psi according to my digital pressure gauge.

Thanx for your observations. I would think you would not want to shift into Neutral going downhill. My 2020 FEH has a hill descent function that slows the car down through regeneration. If you place it into neutral, are you losing out on any regen?

... are you losing out on any regen?
That's the goal: motion without braking or propulsion. Very easy to do in Escape Hybrid; just add throttle to zero-out the right side display, 0/0/0 for regen/EV/ICE.

It's situational. When driving downhill, coasting may be the most efficient option, depending on grade. Regenerative braking captures what would be waste energy, but it's 85-90% efficient. Coasting is as close to 100% as you can get. The only downside to coasting is increased aero drag due to increased speed, road and traffic conditions permitting.

This is very different from steep hills, where speed control is required. C-Max has a Hill Assist button, Escape a menu setting for it. Up to 35kW of regen braking until the HVB is full, then 20kW braking to the bottom (resistive load?).

As fbov said coasting is close to 100% efficient and you can control speed by switching back to Drive to speed up or Regen to slow down. My Range did increase while doing this. I'm currently at about 39 mi. traveled on this charge with 5 mi. Range left, I think I lost 2-3 miles in range do to the rain yesterday. Still 44 mi. is 7 mi./20% better than EPA 37 mi. range. It looks like I can push the range to 50 mi. with my mods installed. I think the idea of using EV on flat road, coasting down hill and ICE uphill is the way to go for the best mileage. If you are going to use the ICE make sure you keep WT above 202*F, 215 -220F preferably for the best gas mileage.

i had to look up gas pods.
seems like they are just vortex generators.
I've yet to see any definitive, repeatable proof that they help. vortices can bend the air to fill the wake, but they themselves have drag. kinda net zero.

a nice kammback would help though...

sounds like you got the driving/coasting/regen thing down. one of the frustrating things on my 3rd gen escape is that when you shift into N, it will hold the revs where they would have been in gear, instead of dropping to idle. kind of defeats the purpose of coasting in neutral. I also wish the Decel fuel cutoff was more aggressive, and would keep downshifting to stay in DFCO. currently just does it in the gear you were in until revs drop near idle.

Neat, we're considering trading in my wife's 2020 1.5 SE for a 2019 Energi Titanium Fusion, I like that I only fill up my hybrid escape about once a month but she drives about 40 miles a day out and about. it's almost a straight over the table trade at this point. I already installed a Nema 6-20R in the garage for use with a 16A 240v Charger.

Another thing about coasting it allows your HVB to cool down some when you don't use it. Was noticeable with my 2013 CMAX Hybrid.

So far I have 331.9 total miles, 312.2 electric mi. and 341.2 MPG. When I got the car it had 395 mi to E gas and currently has 387 mi. to E. It seems to be averaging 47+ mi. per charge range so 10 miles over EPA estimate range. Interesting that after a short 7 mi. trip the electric range goes up 1 mile when you use the car later. The highest HVB temp I have seen so far is 89*F with outside temps high 80's to low 90's*F.
As far as handling goes the FEHP has more body lean in the roundabouts than the CMAX Hybrid, probably from the additional weight in the back. CMAX Energi had less lean, but similar issues.

From an efficiency standpoint it seems to me on a + 60 miles trip it would be better to use the ICE block heater to warm up the ICE and then stay in Hybrid/ ICE Mode to start the trip to keep WT up to improve ICE efficiency. Just HVB at the end of trip when the WT doesn't matter when you don't use the ICE.

Today it became obvious that short trips hurt your range, I have gone 41 mi. with 4 mi. left and I'm not sure I can make it home without turning ICE on. It's kind of close to go down hill some with 4 mi. left to go 7 miles. It usually takes 4-5 mi. of range to get home. So I decided to charge for an hour and a half to get at least 4 to 5 miles of extra range.

I drove to Cleveland and back in EV later Mode for the first time and posted fill ups on Fuelly.com I took a picture of my current tank when I got back. My previous three tanks I averaged 45.4 mpg in the rain. The tanks were off anywhere from 1.5 to 7 mpg. I think I will fill up the tank and see how it is off. Every time you start the car you have to reset to EV Later.

Filled up and the Displayed Trip had 52.5 mpg and Fuelly actual mileage 49.8 mpg, off by 2.7 mpg. I got the total range for ICE miles to 560 miles, divided by 11.2 g =50 mpg. So adding 47 mi. EV range = 607 miles total. Display shows 576 mi. after fill up.

Some more things I've noticed are the WT runs most of the time below 202*F (195-198*F) once in awhile I saw it get up to 207*F in EV Later Mode. It could be cooler in Normal Mode, maybe try it on next trip to see WT numbers. Generally the display for range is over optimistic after charging, this morning I started out with a range of 53 mi. and ended with 37 mi. after going 9.9 mi. which still gets me 47 mi. range for this charge. I have a couple of 49 mi., but most are 47 mi.

Paul, here is a reference from the Ford workshop manual on WT range

Thermostat Opening Temperatures


Starts to open90°C (194°F)
Fully open106°C (223°F

The CMAX started to open at 182*F and fully opened at 202*F, apparently FORD agreed with me that you get better mpg's running the ICE at higher temps. As I said before and have been doing for 8 yrs. 215-225*F is probably optimum for mpg's.

I recently noticed that the Escape 2.5L engine has much less coolant (5.5 qt.) than the C-Max 2.0L (7.8 L). Much more electric coolant, (11.1 qt. vs 1.1 qt.) but less engine coolant. That should speed warm-up.

I have been noticing that if you start the ICE to increase acceleration it will stay on until it reaches 128*F like the CMAX Hybrid did. It took about .8 miles to make it happen.
I charged up to full at work and only showed a range of 49 miles. This was caused from driving uphill to work which lowered the range by 4 miles, if you add 4 mi. to 49 mi. it gives you 53 miles which is the normal range when I charge up at home. I gained 2 mi. back when going to town and back, 8 miles, will see what I end up with driving another 24 mi. when I get home.

How many members have FEHP now?

Paul,
I am still waiting on delivery of my Escape PHEV Titanium.. Dealer still thinks I'll have it before the end of September. I'm not holding my breath. It is being built this month..sure hope the Chip Shortage doesn't stop the delivery.
