Really bad in-city mileage.

[JB330ci]

Maverick hybrid ice is getting ~20 mpg in city and slightly more on freeway. If you only get 20-22 mpg overall you are on ice all the time, little help from the battery. Something is not right.

it's been 75-80 degrees in the mornings. I have driven several other hybrids and they all had lots more low end torque on electric than my Mav.

Have you tried changing the driving modes to see if that has any effect on it?

i do not have my maverick yet but i uber with a 2010 prius and driving aggressively makes little to no difference in my MPG. pretty much 48mpg all the time. when i first got it i tried to drive easy/hypermiling/max regen braking and got worse MPG than i do now just driving it as needed to keep up with traffic in normal eco mode.

with that said in the summer time if i max out the air conditioning i can easily lose 10 mpg. installing ceramic 3m tint at legal levels restored half of that loss.

i can easily lose another 5 mpg if i idle at all with the AC on. seriously one 5 minute wait per day is -5mpg.

you can get a bluetooth dongle for your obd port that will show your battery cell levels by using a free app on your phone. it sounds to me like you might have a charging or battery issue. do remember that the hybrid battery is tiny and using things like air conditioning will destroy your mpg.

Because a prius has no power anyway? Just joking here LOL

Well, they do still only have ~121 HP, vs. the 191 HP in a Maverick Hybrid...

Drive mode doesn't really affect the transition point (except Sport or Tow/Haul where it just runs the engine constantly). The Maverick is certainly a bit pokey at max EV output possibly dictated by what the motor controller is programmed to output rather than a limitation of drive motor capacity. So Ford is possibly sandbagging the power to get away with a lighter current controller, or maybe it's battery pack current limits? My previous '14 Fusion Hybrid had a sort of 'boosted output' EV+ mode albeit only for a 1/4 mile or so before reaching home/work, but it could comfortably get up to 30 mph with much more throttle available.

I was just thinking that something is not right, and it could if the drive modes have an effect on your issue then it would point to where the problem might be. I understand that under normal circumstances that the drive modes would not have much effect.

Do you have climate control turned on? If you are commanding AC then the engine will stay running and not run a lot in electric mode.

Have you reset trip 1 or trip 2 recently? If not what your total mileage and electric mileage? If you are not getting a lot, like 25%, electric mileage, then I suspect the above is the issue. The electric motor is assisting the engine, but the engine is never turning off and going electric only.

I don't get it. I am only averaging 30mpg in my hybrid Maverick. That is 40% town, and 60% highway driving. IF I drive all in town, I average 20-22 mpg. This is done by actual math at the pump, not by the trucks estimate. Here's the thing, I BARELY touch my accelerator pedal, and I can stay in electric up to about 20mph. After that it kicks on the gas engine. When I say barely I mean it takes me two blocks to get up to 20. Now, also, if I am looking at my instant mileage, it NEVER shows more than 8-20 mpg at low speeds but accelerating with the gas engine on. Then I get up to speed speed and back off the pedal to put in in hybrid mode. On the highway I will regularly get 35-38 mph indicated on instant mileage.
Here's my thought and question. When the gas engine cuts in at low speeds (30mph) doesn't the electric motor keep assisting the gas engine? I can't figure out how in the world people are getting over 40mpg.. My truck just doesn't seem to have any power in electric operation.
Before you start thinking I am driving crazy, I'm 66 years old and being passed by other cars all day long. I brake easy and accelerate lightly, backing off the gas pedal to let it kick into hybrid as much as possible.
Bad battery? Bad programming? Bad electrical connection somewhere? Anybody have any ideas? Took it to the dealer, they drove it on the highway and said "It's getting 35 mpg, what do you want?" Well, the big problem isn't on the highway, it's on the damn city streets at sub 40mph speeds!
Or is this just all I can expect? Yeah I'm frustrated. And yes I know how to drive a hybrid.

As others have said that just isn't right at all. You can get 40MPG without even trying in these hybrid Mavericks. My worst trip was 30MPG, and that was in tow haul mode with a load of scrap metal.

Everything points to an electrical, or software problem with the hybrid system, IMO. If the gas motor is running all the time something is very wrong. On most trips (city/rural roads) at least half the trip is in electric mode, regardless of speed. I assume you are driving in normal or eco mode? In sport or tow haul it won't go into full electric very often, but I doubt you would be using those all the time, since it defaults to normal every time you turn it on.

I'm averaging 58 MPG city with my Hybrid, My commute is 17 miles one way, it's all city driving.

 

[MLA62563]

I drive my hybrid like I do any other vehicle. In normal mode without any real effort to economize, I still get well over EPA numbers. This has GOT to be a vehicle issue.

I've put about 290,00 miles total on 2 Prius'. The first 5 minutes when the engine is warming up the mileage is poor but after that you should get in the 40's unless you are going from stop light to stop light. Sounds like there is an issue. Try driving in town at about 30 or 40 mph with the engine warm and green lights. See what that does.

My XL EB does better that that.

MAX AC or max heat both will never turn ice off. Also if not on max the closer to ambient temperature the set temp is the longer the ice can turn off. The drive mode you are in can affect the amount of Regen. One case at say 50-65 mph = slippery the Regen on let off go pedal coasting is less Regen than other drive modes. Therefore with ice at most efficient rpm to provide needed torque for wheels plus enough to generate electricity needed it will maintain that rpm. If there is extra electricity at the current most efficient rpm the extra electricity can be put into the HVB. Instead of fighting the computer to force more battery use let the computer balance the use to the most efficient way possibly. Remember if you force more battery usage that due to the conversion loss of ice energy into electricity and then stored into battery and then withdrawn from battery and then converted back into energy by drive motor it would be better to only use ice at a SET RPM providing just enough excess electricity to store in battery. In this case a lower % of electric miles could give a higher mpg because driver has minimized conversion losses. Also by maximizing battery use more electricity will have to be generated to cool the battery. Which would come from ice. (Any regen energy captured was originally produced by ice and suffered from conversion loss.

Yeah truck computer shows a bit more than the actual mileage, when calculated by hand. I have about 3500 miles on the truck and have NEVER calculated more than 32MPG

Are you still dealing with this issue? Our hybrid is averaging about 39 during break-in with cold temps and some highway driving mixed in. So it's performing quite well with a high of 65.7 mpg trip average. I noticed our range has dropped a bit going into winter, but nothing drastic, doesn't seem like that would be an issue in Texas, and you're already broken in.
