2015 Expedition - Happy with Ecoboost 365HP + 420TQ!

[fugawi]

Two weeks ago I purchased a 2015 Expedition 4x4 with Ecoboost, optional 3.73 axle, Rear Load-Leveling Suspension, and Blind Spot Information System.

My previous car was a 2009 Expedition 4x4 with 5.4 V8.

I am really happy with the Ecoboost. Although I haven't timed it, the acceleration feels much quicker than the 5.4. The Expedition with Ecoboost is actually kind of fun to drive (for a big SUV).

Ecoboost 365 HP and 420 TQ = :B

I did my first towing today. We have a FunFinder 189FDS. I got about 10 mpg with 50 miles of freeway and around town driving. (Our previous tow vehicle was a Jeep Grand Cherokee 4x4 with 5.7 V8 and we got around 8-9 mpg towing on long freeway trips.) The Expedition Rear Load Leveling Suspension seems to work well, and the integrated brake controller seems to work well.

With daily driving (not towing), I get about 15-16 mpg, but I press the pedal a bit more than you need to enjoying that turbo acceleration.

I got about 18.5 mpg on a long freeway trip (not towing) with some ecoboosting, so I'm guessing you could reasonably get 20 mpg on the road (not towing) taking it easy.

(All mpgs are per vehicle information display and are approximate.)

OP: Try towing in 5th with tow/haul engaged. You should hit 11 mpg easy at 65mph, we got over 11 overall towing our slightly larger FunFinder from Ohio to Grand Canyon and back. It'll tow in 6th easy, but it likes 5th better while towing. Trans temps stay right on 195. Except when we made the haul up Wolf Creek Pass and it went all the way up to 204. 🙂

Thank you for this suggestion!

I hope you have many happy miles down the road. Congratulations.

You are correct. That is why the Motor Trend long-term F150 4X4 Ecoboost averaged 14.4 mpg over 30,000 miles and the long-term Ram 1500 4X4 Hemi averaged 15.6 mpg over 30,000 miles. A year of different lead-foot drivers resulted in these numbers. But, I assume a year of careful conservative driving would have resulted in the Ford getting higher mpg.

Either way, to the OP, congratulations on your new ride. You will enjoy the power.

On 10/2/14 I got a fully loaded MKS EcoBoost for a toad. Tuesday getting base plate installed and wiring done.

To bad they only raised the HP on the 2015 Navigator to 380HO with 460 lb ft torque and not the other Ecoboost models.

PS...Congrat's on your new TV and enjoy your ride !

It all boils down to just a few things and the stuff most folks talk
about are not them..except for buddy

#1 is PSI on the piston tops times the area of that piston top

#2 is the amount of energy in the fuel

#3 are all of the characteristics of the laws of physics that play
with #1 & #2

Boy Racers & gear heads have known that since the advent of a hot rodding

The small displacement EcoBoost is forced fed enough air to fill a NA
big block, so it behaves similar to a big block. That is #3 stuff, as
are most of the stuff below

Getting the fuel/air mixture to burn (not explode like most think)
has rapidly expanding gases inside a container...AKA the cylinder/
head/piston top.

The hotter you can get it, the more expansion potential there will be.
Meaning more PSI 'potential'

Ignite it before TDC and now you have it expanding in a reducing
volume container. That further increases PSI. This is where one of the
biggest ills comes into play...pre-ignition, or ping, or detonation

That PSI's affect is factored by the piston top area, the crank offset
(throw), etc

Must add right now, that the piston/rod/crank offset are traveling
at about the speed of sound (IIRC 752 MPH at sea level and normalized
humidity and temp). That, that mass is REVERSED in an instant to
accelerate back to approx the speed of sound. Repeated XX to
over XXX times a second. This is part of what is known as pumping losses

There is a HUGE friction potential and the why of using the best engine
oil you can....plus how it is broken in (the hills and valleys of the
cylinder wall for oil filming)

Ford chose small displacement for MPG and power via forced feeding.
This is what ib516 means managed by the right foot...the ECU's sensors,
sense rate of change, ultimate stroke, etc

GM chose large displacement for power and variable displacement for MPG.
The ECU manages the variable displacement based on feedback from the
other computers on board...all keyed or taking their master input from
the right foot.


Now to 8iron's....yes all ICE's work the same and the modifiers (variables)
makes the difference

On this, know that ICE's most efficient architecture is a 2 cycle diesel
At about 40% efficiency. The rest of the energy is lost in pumping
losses and rejected HEAT

The high MPG of hybrids are due to two things. Two sources of power,
the liquid fuel (gasoline or diesel....toss in propane and the other
forms of liquefied gaseous fuel) and the battery...which has a higher
power density than either gasoline or diesel

False MPG, as the day of reckoning is the day you have to replace the
worn out Li-Ion battery. Tens of thousands of bucks at todays current
cost structure

The same can be said for 100% electric too. Plus using the grid
to recharge skirts the various road taxes...for now



This thread is about the Ford architecture. I'm not a fan of small
displacement ICE's for towing. Especially heavy.

Prefer a larger displacement ICE (why I have a big block GMT400) for
towing heavy. My 2 seater is 2.4L OEM and have a 'built' ICE on
the engine stand. Hogged out block, stroked via diesel crank and
a worked head to be about 3.1L inline 6. The 2 seater before this one
had a 1.8L inline 4. So I also understand small displacement.

Plus I'm a GM fan, but an NOT blindly loyal



The next gen ICE after the above Ford and GM offerings will be GDICI,
which will have even better efficienies

Is there a link on how to post links to my posts. The above is not my own words I got it from:

Let's see if I figured it out. Been a long time since I have been here.

One USA gallon of regular unleaded gas is equal to about 49 horsepower in heat units. In practical terms, about 65% of that is lost when it's burned through an engine.
An automotive engine will produce about 15 HP hours on a gallon of gas. An automotive diesel will produce about 20 HP Hrs. on one US gallon of #1 diesel. That's 20 HP for a period of one hour.
The larger the engine, the better the HP hour rating. A 500 HP stationary diesel can achieve up to 22 HP Hrs. per gallon (US) of diesel. HP hours are generally used commercial and agricultural engine applications.

efficiency is different for each engine. But there is only so many HP you can make per gallon.

Could not the same thing be said for virtually every internal combustion engine with a throttle ever built? Would a statement like " you get to choose one" be more accurate?

My 2005 Expy gets 19 mpg at 70 mph. Probably a lot less mpg than yours in town but pretty happy with it. 3.73 gears as well.

You are the first 2015 Expy owner I have come across. Can you provide some details for me? What is the receiver tongue weight limit with weight distribution? What model/trim level do you have? How much as equipped payload on the tire and loading sticker on driver's door?

It is a regular wheelbase (not EL) 4x4 Limited.

The Tire and Loading sticker on driver's door says "The combined weight of occupants and cargo should never exceed 1,347 lbs."

The manual says the maximum tongue weight is 600 lbs weight-carrying and 920 lbs weight-distributing. It says the maximum trailer weight is 6,000 lbs weight-carrying and 9,200 lbs weight-distributing.

We have had two larger EcoBoost engines (one F150 and one Explorer), and now just one 2014 Explorer with the small EcoBoost.

What I noticed was that it took longer to break them in for maximum fuel mileage. Just turned over 12,000 on this new one and it is getting 26 MPG highway.
