2014 RAM 1500 EcoDiesel Rated at 28 Miles Per Gallon

  • RAM 1500 EcoDiesel rated at 28 mpg highway, 23 mpg city
  • Diesel RAM 1500 is now the most fuel-efficient truck on the market
  • EcoDiesel carries a $2,850 price premium over HEMI V8

If you’re looking for a full-size pickup with an eye on fuel efficiency, the 2014 RAM 1500 EcoDiesel might be the truck for you. That’s because the Environmental Protection Agency (EPA) recently rated the pickup at 28 miles per gallon on the highway, making it the most fuel-efficient full-size truck available today.

In addition to its 28 mpg highway rating, the RAM 1500 EcoDiesel earned an EPA-rated 20 mpg in the city and 23 mpg in combined city and highway driving. The figure isn’t an exact average, since the EPA’s combined driving cycle puts an extra emphasis on city driving.

The strong fuel economy figures will come as no surprise to truck aficionados, since the RAM 1500 EcoDiesel is the only full-size, light-duty truck to use a diesel engine. Most trucks save diesel power for heavy-duty models aimed at commercial shoppers and drivers interested in towing or hauling huge loads.

But the RAM 1500’s EcoDiesel engine isn’t a heavy-duty powerplant. Instead, it’s aimed at shoppers who spend most of their time in normal, everyday driving situations. And that’s where the engine shines, thanks to a reasonable 240 horsepower, a muscular 420 lb-ft of torque and a smooth 8-speed automatic transmission.

Unfortunately, the EcoDiesel’s excellent torque and gas mileage figures include a sharp price increase over other RAM models. Chrysler says the RAM 1500 EcoDiesel carries a $2,850 price premium over the HEMI V8-powered RAM 1500, which makes 395 hp and 407 lb-ft of torque.

Interestingly, the RAM 1500 offers another option for fuel economy-minded truck shoppers who aren’t interested in diesel power. The truck’s 3.6-liter Pentastar V6 boasts an impressive 305 hp but still returns up to 25 mpg on the highway. That engine slots just behind the EcoDiesel as the second-most efficient powerplant among full-size trucks.

What it means to you: The 2014 RAM 1500 EcoDiesel is the pickup to have for shoppers who are especially interested in fuel economy.

  1. I have owned my 2014 eco diesel for 3 months and love it. My first tank of fuel averaged 31.5 mpg from Cortez Colorado to Casa Grande, Arizona. My best was last week when I drove 55 mph on flat highway for 80 miles and got an even 40 mpg. I love this truck.

  2. Well I picked up my 2014 Ram about 3 months ago and have yet to get the fuel milage advertized. I have an average of 19.00. I have do everything Bob Baker’s auto has told me and it still get just a little more than my 2001 tundra. I there a class action suite for this.

    • My reply to your comment would be what type of driving do you do and what type of area do you live in because I do know for a fact epa ratings are not as accurate in the moutain environment as it would be in a flat type area so I’m just guessing they are leaning to the optimal conditions for the high end ,no load ,flat roadway ,and 55to 60 mph maintain speeds ,geographic locations can have a impact in the not desirable milage ,some times a higher horsepower and touque rating can be beneficial to fuel milage , in areas a smaller power plant may work harder to maintain .speed .im not saying that’s it’s right or justifying the means of how they get those ratings but do understand where your coming from .i had a 87 4×4 ford ranger with the stock 6 and got 12 to 14 after I did a 5.0 v8 swap I was able to hit 15 to 18 with the added weight gain of the upgrade full size bronco tranny and transfer case upgrade, case point being a truck that work less get better mpgs then a truck that can be under power for a given situation or area .

    • Hey Bob I have a 2015 ecco and I will say its a tar baby vehicle, got it as a hold over in 2016, mpg is 20.0 and its all highway miles, I keep getting mail from ambulance chasers saying there is some type of lawsuit on the emissions, but can’t get a good answer from the dealership.  Still not bad getting 20mpg but when I tow, it goes down, I was hoping to get better fuel mileage but for my first Ram, its ok.
