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?

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.
