Tested: Slippery Mode is best for highest MPG (in Hybrid Maverick)

[GPSMan]

Daily commute:

11 miles one way.
At 50°F routinely get over 50 MPG in slippery mode with climate control off.
On a good day, can get 7 miles EV out of 11.

Today, same route, same temperature:
Sport Mode
Heat set to 85, blower on lowest setting.
36 MPG with virtually no EV miles. 0.7 EV out of 11.

(the 0.7 was leaving the residential neighborhood in Norm before the first start)

It's not so much about the mode change changing engine settings.

It's all about how many miles and minutes per drive the engine is off.

Very helpful information . . . we just got our Mav and are trying to figure this all out for MAX mpg. Is it possible to set the mode (e.g. ECO) so it comes on in this mode so my wife would not have to worry about making the change?

I read this thread a while back and am in my 6th month using slippery mode. Not sure how long I want to keep going before trying eco mode since cold weather is ending here. Not sure if 6 months on eco from April thru September will be a fair comparison? Might just go the full year and then start on eco.

Can't really compare winter mileage to summer mileage to deduce differences in drive modes. Cold weather is keeping your mileage down; the changing seasons will mask any changes due to the drive mode.

Especially in Ohio!

2nd day of spring, and past two mornings had to remote start for 5 minutes with frost/ice on the windshield. 17 yesterday and 28 this morning. Mileage hasn't been BAD, overall I'm still over 38mpg (haven't reset the trip2 yet). A lot of mixed warm and cold weather the time I got over 600 miles on a tank. Would love to see it up near 45mpg when the weather stays warm.

 

[GPSMan]

It will happen.

I'm at 45 mpg without trying too hard in 45°F mornings and 65°F afternoons.

I'll be over 50 mpg when it becomes 65°F mornings and 85°F afternoons.

Already been discussed here (and many other threads) Mode at Start | MaverickTruckClub - 2022+ Ford Maverick Pickup Forum, News, Owners, Discussions. There is a link in this thread that shows how it could be done, but it's not really that simple.

I'm re-reading this thread and I'm sorry I have some stupid questions.

• How would I ever notice that engine braking is happening? I've heard some say they can tell.
• What is ICE again, and why is it a bad thing? And why is there a band called Hybrid ICE keeping me from finding this out myself when I google the question for myself?
• If sport mode will allow up to 70%, would you say that the next time I get that notification about the pickup going into "deep sleep" mode, I should make sure I take it for a drive in Sport Mode?

A) The easiest way is when/if you are slowing down, coasting, and the engine (ICE) is above idle speed.

B) ICE is short for Internal Combustion Engine - bad only in the fact it burns gas.

C) You could drive in Sport or Tow Haul mode the last 5 minutes of your drive. That will charge up the high voltage hybrid battery, but won't do anything different for the 12 volt battery. Not sure how it would affect deep sleep mode. But in any case, is a band-aid, not a cure for deep sleep.

yeah I knew my questions were stupid. It was never clear to me which battery deep sleep was referring to, and not sure if a drive doesn’t helps the 12 volt battery, then why does the alert say it does. And if not by driving, then how does the 12 volt get recharged? #newb.

Driving charges the high voltage battery. The high voltage battery charges the 12 volt battery.

I have not read very much about deep sleep because I don't have that "problem".

I think the 12V battery is getting low.
But, I'm not sure.

Hello folks-

I did a few well controlled tests on my 2022 Hybrid Maverick to explore the features of the different modes. I now drive in slippery mode ALL THE TIME. If top MPG matters to you; maybe you will too.

I have a ScanGauge III attached to the OBDII port and see data in real time from the Maverick's sensors.

On the same road traveling the same direction for all tests with the HV battery between 41.5 and 42.0% for all tests, I got up to 28 MPH, put it in Neutral, coasted to 25 MPH then without touching either pedal, put in back in drive. This was to measure the amount of regenerative charging. I coasted from 25 mph to 15 mph and recorded the results.

Eco Mode: 34A (7.5kW) at 25 MPH
Eco Mode: 15A (3.3kW) at 15 MPH

Tow Mode: 34A (7.5kW) at 25 MPH
Tow Mode: 15A (3.3kW) at 15 MPH

Sport Mode: 34A (7.5kW) at 25 MPH
Sport Mode: 15A (3.3kW) at 15 MPH

Normal Mode: 22A (4.8kW) at 25 MPH
Normal Mode: 10A (2.2kW) at 15 MPH

Slippery Mode: 12A (2.6kW) at 25 MPH
Slippery Mode: 3A (0.66kW) at 15 MPH

Slippery is best if you want to coast the longest distance without using fuel.
Slippery has given me +10 MPG over Eco in slow rolling conditions such as California freeways at rush hour.

Other observations:
Normal, Eco, Slippery allow EV driving.

Tow/Haul and Sport DO NOT allow EV driving, but will "idle stop" while you are not moving.

Normal, Eco, Slippery modes force the gas engine on when the battery drops below 30% state of charge.

Tow and Sport modes I could not get the battery to 30% because the engine was always running!

There is hysteresis in charging. Sometimes.

In Normal, Eco, Slippery it can start and stop the engine at any battery percent down to 30.01%. Once you hit 30% and below (can briefly hit 29% for example) then the engine must run until the battery exceeds 40%.

In Normal, Eco, and Slippery the HV battery likes to stay in the 30's and 40's for percents. Rarely over 50% SOC. Almost never over 55%.

In Tow/Haul and Sport modes the battery quickly charges to 70%! Presumably so you have more juice at the ready for hill climbing, and presumably, drag racing.

Beware- from 30% to 70% you have full regen braking from the brake pedal, which is 145 Amps (32 kW). At 70.2% my regen brake limit went from 32 kW to 7 kW in one step. Surprised me it wasn't a taper, but this was day one of data collecting.

Hi John.

Have you compared regular to premium fuel yet?

Thanks for the study so far.

I need to try the Slippery Mode myself now.

All the Best,

Spartan.

I’m trying to follow all this however my COVID rattled brain can’t keep up. Would someone please cut to the chase and say what gives the best mileage. I just bought my third tank of gas. This tank was 95% my wife driving in the standard mode. I filled up with 568 miles on the tank averaging 40.2 mpg. My goal is to hit 600 miles on a tank without running out of gas. Where I live there is a combination of rolling hills and flat land. I try to drive in eco mode and most of the time I can get the truck back into the green once at the top of the hills.
The gas mileage game is what reduces my regret for not buying the 2.0 engine with a trailer towing package.
Speaking of trailer towing has anyone had any experience towing a light trailer with a hybrid? I need to be comfortable with this or sell my boat.

I've been back and forth between eco and slippery, and I'm not sure I've noticed a difference. It's really hard to tell without exact comparisons. But some days you'll have heavier traffic and more start/stops. The next, not as much traffic with fewer start/stops. I've seen it better on eco one day, the next it's better on slippery. I'm not sure what is best.
