YES the eco boost is imo great.
I had my 1st exp with the new setup in my 2013 f150 4x4 3:55 gears, traded it with a 2010 5,4 3:55 rear gears.
in the pickup i could get 18-19 highway at 75mph it weighed 5700 lbs empty
17 city we are rural so most of the city is 5-6 miles at 60 mph and a few blocks at under 30, stop and go, with one four way stop sign
the 2016 expy 4x4 with 3:73 rear gears gets a boost in hp over the 2013 engine. we went with the El to get the 3:73 gears, the 3:55s were good in the pickup as well. but the expy is a bigger wind killer and able to hold 7 warm bodies, we mostly have two and then our tow big dogs that really enjoy the rear leg room compared the backseat of the pickup
i drive real world speeds, as in keep up with traffic
we are rock steady after 10k miles to get 17.3 at 75-85 mph, with occasional 90 plus
city short trips will run up to 18 plus.
I can get 20 mpg on highway if i hold her back to 65, but thats boring.
and it weighs 6400lbs empty and flat shiiits and gets.
40 -60 passing is OMG fast and you will fly through 80 real quick in 5th gear.
now i did a couple hundred mile with the composite cross ties on the trailer, ran 65 as that the limit on trailer tires or at least thats the sidewall stamp. they weigh right at 300 lbs each and i had 19 on board, 5700lbs plus the 2000 trailer weight so just a shade under 8000 lbs out back
pulled down 19 the whole way home and almost no downshifting, it has gobs of tq.
yes its packed with computers and sensors, but dam fun to drive.
