Getting a new truck, compare RAM EcoDiesel vs F150 Platnum??

DP is full of crap sometimes.

Turbo's have been used for years in HD diesel trucks, I see no reason they won't be just as reliable in gas trucks especially since they use the same block materials.

I'd bet we'll eventually see ecoboosts in the F250 and F350 trucks, the 3.5 EB has been out for more than 5 years now and has a good track record for reliability so far. Ford essentially had to prove the engine out for light duty trucks (F150) before they'll get guys that really work their trucks try one out. I'd say it's doing it's job, some people buy the 5.0 Coyote because they say "a truck without a V8 isn't a truck", but Ford sells way more ecoboosts than they do V8 F150's now.

I agree though, the ecoboost doesn't offer any fuel economy savings when it's working, it'll actually do worse under load than a N/A engine. The thought process is that they engines aren't under load very much, that's the same reason GM is doing the cylinder deactivation thing.

 

If they did an ecoboost in 3/4 and 1 ton trucks it would hurt diesel sales. I would not be surprised to see ecoboost in a HD truck in the future with tighter emissions requirements.

All GM'S suck too!

 

I believe ford no longer offers the Cummins. Could be wrong though.

Yup I know I looked at the data and I also said I'm sure hyper milling its very doable(which alot of people do on that site). Thats why I quoted the 20mpg post.
You also see some seriously poor numbers. Probably average drivers.

The independent study you suggested is a tuning and dyno service specifically for the Ecoboost lol.

I'd rather believe SAE numbers. Or facts as I call them. (They do it for towing now too)Sometimes engines are underrated but ford isn't known to do that, plus for the drive line loss(15_20%) they would have to underate alot.
Again towing under boost in a FI small cube motor is backwards.

To me somones butt dyno or magazine article about drag racing a factory stock slow truck is meaningless to me lol. Might as well talk about who's Prius is faster.

I don't drag race towing other trucks, its efficiency while towing that would interest me.
They are both SAE certified towing x amount of weight, do the math with gvwr and they both come out within a few hundred pounds.

 

I HIGHLY doubt there's enough hyper milers to skew the data much. Just like any vehicle, you've got the guys that drive it like they stole it and the guys that drive like grandmas. That's why it's nice to look at the graphs and see the average but also the spread. That's why I like fuelly, and the average mpg on there is pretty much spot on what I get on any vehicle I've owned and I'm certainly not a hyper miler.

And 5 star tuning offers products for both Ford and GM tuning. So I'd call that independent.

And please don't compare a Prius to a truck lol! Stock trucks these days will run a low 15 second 1/4 mile, and that's with a crew cab 4x4. That's scooting for a 5,000 vehicle! I only tow about 5 times a year, but I drive my truck to work every day so the acceleration is much more important to me than fuel economy while towing.

 

If we want to start talking hypermiling this is pretty amazing:


Hypermiling a Ram 1500 EcoDiesel to 38.1 mpg and over 1,000 mile on one 26 gallon tank

Also talks about getting 30mpg in a '11 3.5 ecoboost f150. Good read and really amazing to be talking these types of numbers for full sized trucks!

 

Fuelly is right on with what we get in our 04 Sequoia once you sort options. But I am at the very top of their charts in my 01 Highlander. But I just drive about 60 mph on a 2 lane highway with a few small towns...like the kind you just drop down to 45 mph for, for a half mile or so. And that's about the extent of that vehicles miles so that explains the better than average mpg.

I like Fuelly to see real world mpg cause its really close. If I put the app on my phone I'd track it and I'm no hyper miler. I try to get the best mpg I can but don't coast and feather the gas or turn at full speed or cut my vehicle off either. So if I turned in my miles on my toyota I would have solid data but yet be in the top 5% once sorted for options but I am no hyper miler.

 

5 star is not independent, their bread and butter is fords, but hey we got an Intake for your Chevy....

I can prove it with known numbers and math I'f you care to take a listen......

In their video of their tuned Chevy it puts down 275... Thats a 30 hp gain to the wheels...which doesn't happen. Or they lied about their other dyno (2.7vs5.3)results....
Check all the forums and Google all you want for similar results, they are selling stuff. They are not unbiased and should not be taken as factual.
Here is more info using the supplied facts.

According to their dyno...
The parasitic loss for the Ford was 20℅
The parasitic loss for the Chevy was 31℅
This is using SAE numbers vs their dyno results.
Another fact unless the Chevy was dynoed in 4 wheel drive with mud tires it did not loose 31℅ through the drivetrain.
Every car truck (gm) that I've seen dyno with a 60e variant are between 15-20℅. Even the 80e variants are around 20℅. You can google it all you want too.

So if we give the Ford a huge HUGE benefit of the doubt and the Ford Ecoboost is making an extra 10% to the wheels then I think they would be advertising, or Chevy is lying about their SAE ratings. Which they are not because that's what SAE does its standardizes hp testing.(Chevy has been known to underate their motors)

Another cool thing about SAE when auto manufacturer's agreed to it....Honda Toyota Ford dodge all had their newer model year cars trucks with the same motor trans combo.....with less advertised hp! Because they were scientifically being tested! In a lab on a dyno under the same conditions etc.
Same thing with small engines honduh again was a huge offender.
Now they advertise CCs or cubic Inches.

 

After reading every post in this thread, I have decided to sell my truck and buy a car! Focus or Cruz??? Help a brother out!

Did I hear someone mention CUMMINS I6 Torque from idle to redline of 3400 rpm.

 

Most of the 650 and up have a Cat. For that size truck and gearing it's a better choice really. More displacement and torque over the 5.9/6.7.

 

Think of a lever, the cummins has more leverage, giving it more torque across a wide rpm range. The inline arrangement makes it possible.
I personally like the cummins but personally think the trucks they go in are lacking in many ways.

 

Keep in mind that the Cummins has 6 rods doing the work of what 8 do in a Powerstroke or Duramax.

 

We are going to see more and more smaller engines with less cylinders so they can meet emissions regulations. Look at heavy equipment and how they keep more power out of smaller engines with less cylinders. The more cylinders you have, the more friction there is and power is lost and the engine is dirtier.
