Hybrid vs Eco for mostly highway driving.

[Deleted member 1483]

If the hybrid is not receiving electric assist, the EB should get better highway mileage because because it has a 2.0 liter engine, and the hybrid has a 2.5 liter engine.

The hybrid uses a 2.5L Atkinson engine which has a higher thermal efficiency than a standard otto cycle engine. It will provide more work for any given amount of fuel used.
Atkinson cycle - Wikipedia

And on a level highway at constant speed, there will be no electric assist.

The hybrid ALWAYS has electric assist. The engine will charge the battery to keep it at a middle level of charge (say under 80%) at all times. I've noted "all electric" use at speeds of 80mph.

After the first few score miles or so, the battery will be depleted, and at a constant speed, there will be no regenerative breaking to recharge the battery.

In a hypothetical flat space, sure. In Pennsylvania, plenty of hills for me to recharge.

The 2.5 l. engine will be powering the Maverick entirely.

The Hybrid will always have electric assist.

So any recorded improvement in highway mileage—after driving long enough to deplete the battery—should be attributable to the transmission, and not the IC engine or electric motor.

I imagine the hybrid is more flexible not dropping out of overdrive on every hill.

If the overall revs/ mile is not significantly different though, then after a certain number of miles driven after the battery is depleted, the overall highway mileage will equalize between the EB and the Hybrid, and thereafter the mileage will be better for the EB because of its smaller displacement.

I get 37mpg when I drive in sport mode with the engine on full time. So... no.

So what I should understand is that at the same RPM as an Otto cycle needs to overcome rolling resistance and air resistance to maintain a constant speed at a level grade, the Atkinson cycle will produce enough additional energy to charge the HV battery as well? Or is there a more correct way to understand this?
And if you are traveling at a constant speed on a level grade, when will the battery energy ever be tapped?

I get where you are coming from, but the best argument I will make is the engine charging the battery is the only reason they are even close in milage.

No one has brought up another major difference,, difference in weight. Whats the difference between the EB and Hybrid.

Maybe my California is showing, but how do you not drive 80 mph?

I am averaging 28 mpg in town and I went on a 150 mile round trip on the highway Saturday and averaged 36.9 in my Lariat Lux FWD with Ecoboost. I was really impressed with the highway mileage. That was with 4 adults and driving the speed limit, in Eco mode, and running premium fuel. I think that the 18 inch Michelin Primacy with Low resistance rolling tires helped. I have not been able to duplicate that in my wifes XLT AWD FX4 with 17 inch Pirelli's and different gearing. Hers averages about 3 mpg less on both highway and city but she has a heavy foot too.

Get the Hybrid for mostly Highway driving. I have the EcoBoost and I’m averaging around 35-37 on Highway and 32-33 in town driving. I’m pleased with my results. The Hybrid will get you 10 additional mpg.

The hybrid will always get better milage.

Even if it was just FWD, it would get better gas mileage than an AWD.

Not sure what “BS” you’re hearing, but pretty much all us Hybrid owners are getting mileage better than EPA. I am constantly getting 600 miles per tank and currently averaging 51 mpg with some highway driving mixed in daily.

I've always gotten slightly better mpg numbers than the EPA on my Fords. The reverse Of Hyundai owners, Lol.

I've done A lot of road trips over the years and the highway speed makes a difference especially on a taller vehicle. Seems once you start going over 70 mph is when your gas mileage really starts gets affected. I see some of these yahoos doing 90 on the interstate like they are in a big hurry. Probably easily taking a 3-5 mpg hit going those speeds.

New Maverick delivered this week. Quick question. After each individual trip, when I shut it down, it shows my Trip mileage for that trip with both gas and electric miles. How do I set to to show me cumulative before a reset. This first tank has me driving 225 miles but How do I see how many of those were electric?

In my analysis, for vehicles with comparable body styles, the most important figure of merit in determining mileage at a level grade and constant speed is the product of engine displacement times engine revs per mile. This is because there is one fuel:air ratio which optimizes emissions, the stoichiometric ratio. Since the fuel:air ratio is constant, gas usage will vary with the amount of air breathed by the engine each mile. Air volume will entirely depend on engine displacement times the number of times the air is displaced each mile. That in turn will depend on tire size, transmission top gear ratio, and differential ratio.

If the hybrid is not receiving electric assist, the EB should get better highway mileage because because it has a 2.0 liter engine, and the hybrid has a 2.5 liter engine. And on a level highway at constant speed, there will be no electric assist. After the first few score miles or so, the battery will be depleted, and at a constant speed, there will be no regenerative breaking to recharge the battery. The 2.5 l. engine will be powering the Maverick entirely.

The other variable, though, is overall revs/ mile. That is something of a black box for Maverick. Ford lists the top gear ratio and final drive ratio for the EB in its technical specs, but not for the Hybrid. But it’s possible that the Electronic continuously variable transmission on the hybrid lowers the revs/ mile more than enough to compensate for larger engine size. So any recorded improvement in highway mileage—after driving long enough to deplete the battery—should be attributable to the transmission, and not the IC engine or electric motor.

If the overall revs/ mile is not significantly different though, then after a certain number of miles driven after the battery is depleted, the overall highway mileage will equalize between the EB and the Hybrid, and thereafter the mileage will be better for the EB because of its smaller displacement.

Your analysis completely ignored Atkinson cycle versus Normal. Do better.

Just a simple question, no disrespect meant. If you needed a good millage car/truck to mostly run interstate then why a Maverick? There are better options.

Agree!
I always drive in ECO mode. My driving is mostly city (let's call it "suburban," with a minority share on the interstate/limited access highways). I'll do 5mph above almost all speed limits (except on 65 or 70mph highways where I'll just do the speed limit). When I've got no one behind me and am coming to a stop-sign or light, I'll let the Mav coast in as much as possible. I go easy on the pedal when accelerating from a stop (but still seem to be accelerating a lot faster than cars in my rearview mirror). Result? My worst MPG at a fill-up has been 44MPG, my best has been 49MPG.

ADDED NOTE: BTW, my Mav's dashboard MPG calculations are not untrue lies. My by-hand averaging comes out the same as the dashboard's.

There's a non-full EV truck that gets better highway mileage than a Maverick?

The concern is overall cost; Maverick is both the cheapest and most fuel-efficient truck there is - period.

They Hybrid Maverick (at least in XL and lower level XLT) is the least expensive vehicle Ford offers, one of the least expensive new vehicles available, perhaps the least expensive new hybrid available, and full of utility. Sure, you can get a vehicle with better highway MPG numbers but not with the same features and the low price.

Just took a trip to NM from Phoenix. Lots of elevation change. Loaded with a family of 4, luggage, 4 mountain bikes and tools, still did 36-37 highway doing ~78mph.

Generally though we do 42-44mpg (70% highway) and go 65-68mph. Tons of AC use.

The hybrid should be your choice unless you want a little more power or the needed power to tow 4k.
