Eco Boost vs V8

[RobertN]

I find it interesting, that for an "Eco" motor, it may burn clean, but still only gets 20ish MPG. It's 2014; I would expect better mileage for an all new "Eco" platform.

Reading here and other places, it seems to be a really nice motor. But still only 20ish mpg...

This is a dumb question but I've been reading this thread hoping to learn what "Eco Boost" means. I have searched it and it seems to mean an engine that is turbocharged and has electronic ignition for fuel delivery. Don't lot of engines do this and why is Eco Boost different or special?

It gets 25 highway in the Taurus SHO, a 4400 lb car. That is no econobox, it is big and fast.

I am not saying it is not a strong motor; everything I read from multiple sources says it is a decent rig. Re; Taurus, my Jag XJ8 will do 23-25mpg on the highway when we head to the Bay to sail. It is big, and will go really fast.

My point is still, if you try to sell me something "Eco", in the year 2014 I would expect better than 20ish mpg.

It's not only turbo but directly injected like a diesel. What makes it so special is 3.5L, mor usable power than any current V8 twice it's size while getting 20 or better economy. Chris

Gotta call you on this one

Lol, let's talk efficient...

My V10 just returned 11.9 mpg on a 400 mile trip, only slightly loaded with 4 passengers and a few hundred lbs in the bed. It's a big truck and it hauls/tows alot, but sometimes I miss driving my 1/2 ton around that averaged 15+ all the time.

To the OP, the F150 would not be my first choice for a 1/2 ton truck ... but since you're looking, I would suggest going with the EcoBoost over the 5.0, mainly because it seems to have more power in reserves than the 5.0, and at least now that its been out for a couple years, most of the kinks have been, or are being, worked out.

Thats average. Every drop of gas. It pulls trailers, idles with the remote start, is in 4x4 50 miles or so a week. Comparable GM and 5.4L F150 it replaced hovered at 13 mpg doing the same driving.

Tell that to this guy that had his ecoboost replaced THREE times because they kept blowing up on him. http://www.f150forum.com/f70/first-time-my-eco-blew-up-208912/

I read the entire thread sometime ago and there were a couple of people who seemed to know a little more about the truck and driver- and they stated that there was more to the failures that was NOT posted on the thread before it was closed.
I got the distinct feeling that a high powered tuner may have been used ?? If there were a bunch of these 150 eco boosts blowing up I am sure it would be on the internet somewhere-I have not seen it.

What I have seen is Consumer Reports removing it from the (recommended list) do to engine problems - but CR admitted it was due to sensor and ancillary part failures NOT a major internal engine failure... That has happened to every manufacturer at some time.

Heck my Dodge has just been recalled due to the left tie rod (which can fail Unexpectedly and cause loss of control)...

to each there own - the Eco boost has a really impressive power band with great torque output at a very low rpm and also a very wide torque curve that is also exceptionally flat.

My guess is the average owners mileage is little lower on the ECO boosts because they are a blast to drive with the power they make- (hard to keep the foot out of the throttle)

Looks to me like the actual mileage is quite a bit lower than claimed. About the same as any close competator such as a 5.7l Hemi powered RAM.
Real world F150 Ecoboost Fuel Mileage

I can see pros/cons. On the one hand it has a nice flat torque band. On the other hand it's a V6 stressed with high pressures both internal, and fuel related to perform like a bigger V8. Since the resulting MPG is the same in real world testing, I personally like the real thing... the V8.

I had the 2010 f150 with the 5.4 v8 in it and now have the 2013 with the ecoboost. Hands down the ecoboost is faster has better gas mileage and is all around much more fun to drive than the old v8. I leased both vehicles so was not planning on keeping this f150 past the turn in date but that may have changed. The new model needs to be that much better than the 13 was over the 10 for me to trade it in. I have 27000 miles and enjoy driving every day. Average around 16 miles a gallon on a heavy foot

Gotta agree with you about the 5.4.

Leased a '06 FX4 and it was a pig until about 80km/hr and then it would really move. Not good for city driving, not good for towing and not good on gas mileage.

Always felt like I had to mash the skinny pedal to make it go.

I was told this was due to a high stall speed.

Haven't driven an EGO BOOST Ford but can relate with 2 previously owned turbo cars. They are FUN to drive...
