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 = :BI 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.)

Congrats on the new Expedition. My FIL has the F150 Ecoboost and I can attest to the acceleration of it. I didn't floor it because he was with me but it has a lot of mid range power. A lot more power than the 5.4L (300hp) I had in my 03 Navigator.

Hi,My sister traded in her nearly new 1500 GM truck for a F-150 Ecoboost. She is really impressed with the power too! They used to have a 5.4L Expedition as well. Make sure that you are using 91-92 octane gas while towing, or it might tend to ping, and the controls will change the timing and inject more fuel to prevent pinging, thus less MPG while towing on lower octane fuel. I notice that my MPG also is less on lower octane fuel in my Kia with direct fuel injection. I get 33 mpg with 92 octane, and only about 28-29 with 87 octane. Have fun!Fred.

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.

Congrats! If they had the EB in 2012, I probably would have one!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?

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

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.

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.

That's the thing with an EcoBoost. You can only have one. Eco, or Boost. Your right foot chooses.

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?

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.

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.
