The EPA hasn't officially tested the Ram 1500 EcoDiesel, but luckily for us Motor Trend Magazine has. When subjected to the Motor Trend Real MPG test, the Ram 1500 EcoDiesel put up an impressive 28 MPG on the highway.



Motor Trend's MPG test involves an "88-mile drive cycle" to simulate real world driving. First the four-wheel-drive Ram 1500 EcoDiesel ran through the test and came out with a rating of 19/26/21 MPG city/highway/combined. That's much better than the Ram 1500 4x4 that runs on a Pentastar 3.6-liter V-6, which gets 16/23/19 MPG.

Next is the rear-drive Ram 1500 EcoDiesel. It posted 18/28/22 MPG. Compared to the rear-drive Ram 1500 with the Pentastar V-6, which the EPA rates at 17/25/20 MPG. You can see that the EcoDiesel really improves over its gasoline-powered predecessors.



The Ram 1500 EcoDiesel produces 240 HP and 420 lb-ft of torque with its 3.0-liter turbodiesel V-6. It's biggest draw is its amazing fuel efficiency though. The truck's towing and hauling capabilities aren't sacrificed for this fuel efficiency either. Depending on a few factors, Ram says that a 1500 EcoDiesel will tow up to 9,200 pounds, which is 1,750 pounds more than the highest-rated 1500 V-6.

Now, these numbers aren't official EPA ratings, but often times real world MPG figures are more reliable than EPA ratings anyway. Ahead of EPA ratings, Ram said that they were confident that the Ram 1500 EcoDiesel would get rated at or above 27 MPG on the highway.

Does this match up with what you guys are experiencing in your trucks?

it wouldn't shock me if some aftermarket tuner comes along with a tune that will extract more power, it can happen.

well the thing about diesel is the fuel itself contains 15% more energy that petrol, so there is a little bit of play with tuning before you really see a drop off in economy...

Depending on the tune there will be a drop eventually but in the end you're still ahead in the fuel economy game than guys running gasoline engines.

definitely a welcome change for RAM faithful.

Was just looing at real world numbers on fuelly, averages for RAM 1500:

2011 14.7 MPG, 45 cars over 425K miles
2012 15.3 MPG, 72 cars over 620K miles

The stellar fuel economy of the Diesel Ram is why i am looking into the truck. Perfect for hauling, towing, commuting, basically everything and anything I could want to do with it.

It seems like there are multiple sources that are saying 28MPG highway is achievable.

To compare to the 5.7L V8, fueleconomy.gov states that the 5.7L 6 speed auto RWD gets 20mpg on the highway. The 3.6L V6 AWD gets 23mpg on the highway. And the RWD V8 8 speed auto gets 22mpg. The RWD 3.6L with the 8 speed gets 25mpg highway.

You can compare them here

I hear that Ford's EcoBoost engine in its new aluminum framed F-150 is going to really boost fuel efficiency. Is anyone thinking about switching from the Ecodiesel to the next-gen Ford F-150. A big reason why I was considering the Ecodiesel was its fuel efficiency.

Even it's control arms are like this, made out of aluminum.

Another thing they need to do is make it public how much weight has been saved by doing this.

The new F150 might just get great mileage

We will see when it comes out

Thing with EcoBoost is that it only conserves gas if you are driving it lightly. If you are always full boost it will still devour gas. And the lightweight does mean it picks up with less effort but if you are towing or carrying lots of weight it still will have poor mileage

I'm more interested to see the the new F150 go against the Diesel Ram in a mileage test when carrying a full load.

Also looking forward to see what it's towing cap will be like compared to the ram diesel, ford has been known for high towing caps
