Ford releases fuel numbers for the new F-150

Because a turbo is not producing boost until it's spun up. If a turbo was producing boost all the time there would be no efficiencies to be found.

You are incorrect. Between the throttle plate and turbo, pressure is always positive when the engine is running. Only place vacuum exists is the intake manifold downstream the throttle plate during low engine loads.

I must be missing that chart on my tablet, because from the text it says they are all able to accelerate from 60 to 70 mph, on a steady 6% grade.

Here is a snapshot of part of the chart. The Dodge is really struggles over 60 MPH with the trailer. That would be a non starter for me. Who does not tow at 60?

I agree. I test drove the ecodiesel and when they hit the dealerships and reported on this site that acceleration felt good until you reached Highway speeds and it ran out of breath. That is where it's low HP numbers become evident. The 3.5 liter ecoboost shares the 420 lb ft of torque as the ecodiesel but has much higher HP numbers to make it superior in towing.

Also notable is that they did not tow up a grade, they towed on the flats. It looks as if they wanted to not have the Dodge left at the bottom of the hill behind the Ford and Chevy. This article is obviously biased against the Chevy and for the Dodge. The Dodge is a really good truck, but you cannot ignore towing at 60 MPH and passing at 65 and call it truck of the year. Fuel costs per mile are almost the same as the Ford once you adjust for the higher diesel price. Diesel is about 20% higher depending on where you live negating the 21% higher MPG figures they tout.

Still think most people buying the Ram eco diesel are light towers who are in it for the mileage- but need a truck. Also many people are still driving the early 1990s Dodge Cummins combos-and pulling trailers with similar power ratings to the new eco diesel.

When a hyper miler can squeeze over 40 mpg out of a new one with 1000 lbs. in the bed on a Chicago to San Diego trip. 2014 RAM 1500 EcoDiesel Heads West - Page 11 - CleanMPG Forums


It shows the truck has great fuel saving potential.
and with a 5 year 100,000 mile warranty there is some piece of mind.

Maybe a Ford owner can point to a truck mileage test run with good (similar) #s ?? - but haven't seen one yet.

Sales of the 2015 F-150 2.7 versus the Ram eco diesel ??? Should be interesting

That truck is a 2WD, regular cab and loaded with what looks like a lot less than the "1000 lb" load quoted. Properly loaded, I bet it could even fit in a Prius which would be an interesting comparison with a driver like that.

Don't get me wrong, the Dodge is a good truck, but the 2015 Ford is much more innovative. Personally I think Ford should put a diesel option in the F150, not for economy purposes so much, but to attract the diesel diehards.

My reading comprehension must be off, because it pretty clearly says that this was an acceleration test on a 6% grade.. Accelerating from 60 to 70 on a grade like that requires a ton of power and it's not something I would personally expect any half ton to do on a regular basis.

You are incorrect. Between the throttle plate and turbo, pressure is always positive when the engine is running. Only place vacuum exists is the intake manifold downstream the throttle plate during low engine loads.

I guess someone... with one of these machines will have to put a boost gauge inline before the throttle body to actually measure it.

I believe the trailer towing was on level ground. See the very beginning of the snapshot, where it says they are leaving the grade behind and scrounging up a trailer. Then they talk about freeway ramps, cornering, etc.

I have a boost gauge but it is downstream the throttle plate so I do see vacuum at idle and under light loads. I have read others who have verified the always positive pressure on Ford forums. Haven't done it personally though. I have a torque app with the obd2 reader and will check to see if that is captured somewhere on the ecu. My boost gauge is mechanical and plumbed to the intake manifold.
