http://www.allpar.com/news/index.php/2015/01/ram-boosted-to-29-mpg

f 28 miles per gallon (mpg) from a full size pickup was not enough, Ram has the answer: 29 mpg.

This number, which beats the highway fuel economy of many sedans, comes courtesy of work on aerodynamics, parasitic losses, an eight speed automatic, and a VM diesel imported from Italy. (Chrysler’s relationship with VM extends back to before the company was acquired before Daimler, but it only used VM diesels outside of North America.)

The 2015 Ram 1500 EcoDiesel HFE will deliver the highest fuel economy of any full size truck, as the 2014 Ram 1500 EcoDiesel did. The city mileage is 21, and combined mileage is 24 — also beating all pickups.

“Fuel efficiency is at the top of truck buyers’ priorities, and Ram is the recognized benchmark for the industry,” said Bob Hegbloom, President and CEO – Ram Truck Brand. “Twenty-nine miles per gallon cuts through the clutter. Ram invested in powertrain technologies and those are paying real dividends in the wallets of our customers.”

The fuel economy king, to go on sale late in this quarter, has a unique trim package on the Ram 1500 Tradesman Quad Cab four-door body, with a 6-ft. 4-in. bed and 20-inch wheels. The Ram EcoDiesel also is available with a body-colored fascia from the Ram Express model, not available on other diesel Ram 1500s. Wheel-to-wheel side steps and a tri-fold tonneau cover offer add functionality and help to create best-in-class aerodynamics.

Here's a better write up from FCA Media:

Ram Has “Turned Up the Eco” on Fullsize Truck MPGs … to 29
FCA Media

  • Ram 1500 EcoDiesel HFE increases highway MPG rating to 29
  • EcoDiesel tops next nearest competitor by 12 percent
  • 21 MPG City and 24 MPG Combined are highest EPA ratings for any pickup
  • EcoDiesel HFE will be first diesel powertrain offered in Ram 1500 Express model

January 13, 2015 , Auburn Hills, Mich. - The Ram Truck brand today announced that it will add a new, more fuel-efficient model to its half-ton truck lineup and further extend its claim on the industry’s highest fuel efficiency rating.

The 2015 Ram 1500 EcoDiesel HFE will deliver the highest fuel economy among all fullsize truck competitors -- 12 percent higher than the next-closest competitor. Its “HFE” designation is Ram’s way of highlighting this model’s excellent fuel efficiency.

Ram EcoDiesel HFE gets an EPA-certified 29 mpg highway fuel economy rating. EcoDiesel HFE’s city and combined mpgs are 21 and 24, respectively, also highest among all pickups.

“Fuel efficiency is at the top of truck buyers’ priorities, and Ram is the recognized benchmark for the industry,” said Bob Hegbloom, President and CEO – Ram Truck Brand. “Twenty-nine miles per gallon cuts through the clutter. Ram invested in powertrain technologies and those are paying real dividends in the wallets of our customers.”

The fuel economy king features a unique trim package on the popular Ram 1500 Tradesman Quad Cab four-door body, with a 6-ft. 4-in. bed and 20-inch wheels. The Ram EcoDiesel also is available with a body-colored fascia adopted from the Ram Express model, which gives the Ram EcoDiesel HFE a sporty exterior appearance not offered on other EcoDiesel-powered Ram 1500s. Class-exclusive wheel-to-wheel side steps and a tri-fold tonneau cover offer owners a double-bonus: greater functionality and best-in-class aerodynamics contributing to better fuel efficiency.

“The Ram 1500 EcoDiesel delivers dominant fuel efficiency across five configurations and nine trims,” said Mike Cairns, Director – Ram Truck Engineering. “The Quad Cab is a widely purchased configuration which delivers the best aero benefit of any half-ton truck.”

Ram 1500 EcoDiesel HFE models will also get a new HFE badge that heralds its MPG claims.

The EcoDiesel HFE will go on sale late first quarter of 2015.

Ram 1500 -- the most recognizable pickup on the road -- delivers best-in-class fuel economy with a truckload of pioneering, fuel-saving systems and first-in-segment technologies: TorqueFlite eight-speed automatic transmission, stop-start system, thermal management system, pulse-width modulation and active aerodynamics, including grille shutters and air suspension. The Ram 1500 delivers an outstanding combination of best-in-class fuel efficiency, unsurpassed torque and a surplus of towing capability.

The EcoDiesel-powered Ram 1500 earned a 29 mpg rating from the U.S. Environmental Protection Agency (EPA), the best highway-cycle test result ever achieved by a full-size, half-ton pickup. It also exceeds the EPA highway rating for the top-ranked small pickup.

Ram truck offers models designed for a wide range of buyers, including outdoorsmen, tradesmen, first-time buyers and ranchers. Laramie, Laramie Longhorn and Laramie Limited trims are designed to meet the high expectations of affluent pickup truck buyers looking to combine capability with sophistication. Featuring premium materials, such as full-leather seating, real wood interior components and modish design, Ram offers a refined luxury alternative uncommon in pickups.

The power of better aerodynamics. I can only imagine how much better the mileage would be on the Silverado/Sierra if GM got serious about aerodynamics. GM has the worst among all except the Titan, if I'm not mistaken. Better front end design, shutters, and wheel arches would go a long way in keeping the truck in 4-cylinder mode a lot longer.

Good job RAM!

In other news, with the drop in gas prices diesel is now close to twice as much as gas meaning your truck would only need to get 15mpg, highway, to be as financially beneficial. Maybe diesel is a little cheaper in your area, then your truck needs to get 18mpg highway, well below what gas trucks are rated for on the highway. Nevermind the upcharge for buying a diesel.

Someone go buy Sergio a calculator.

I see gas at $1.85 to $1.99. Diesel at $3.20 to $3.99

Not trying to detract from the Ram ED but......

The GM 1500's are class leading V8 gassers.

Then there is the Canyon / Colorado Dmax.

Maybe they will be first to break the 30 mpg crescendo.

Nice truck but diesel is 90 cents more a gallon than regular gas around here and the difference between buying the diesel over the gas engine means you'll be dead when you break even cost-wise.......but if you like diesels and don't mind the extra cost it looks like a good truck.

I understand they are class leading V8s. I'm talking about the aerodynamics of the 1500s. If they could get the coefficient of drag down from the .41 that they are currently to, let's say Tundra levels .37, theoretically the engines could stay in 4-cylinder mode longer and potentially under more situations.

Such an old arguement. Tell me the cost difference when you go to sell (if you ever do) that diesel truck as well. Cant argue oil changes either as the new 5.3 uses 8.5 quarts.

At 24 MPG combined compared to 17 MPG combined the difference is pretty pronounced. Thats a 21% improvement right there. However, the fuel is currently 39% more expensive but that will continue to come down. Diesel is slower to react to price differences than gasoline.

If you do any type of light towing the diesel is awesome. Edmunds did a towing bit with their Ram Ecodiesel with about 5500lbs (they didnt scale it but they know their trailer weighs in around 4k and the bed was loaded) and they averaged 18.9MPG. This was over 1K miles in towing so it wasnt a 100 mile loop.

No one knows the resale values of the Ecodiesel, so don't pretend you do. Current diesel trucks are 2500's and much different, much more expensive than gas trucks (8k option for diesel IIRC) so that's not apples to apples. The Ecodiesel doesn't have the heavy duty aspect of the Duramax/Cummins what have you, they don't even match 1500 gas numbers, so don't act like you can transpose the 2500 diesel numbers vs 2500 gas numbers onto a 1500 comparo.

There is a gas station by my house where diesel is more than 100% MORE than gas, but most places are 50-60% more. It's been that way for over a year. How's that 21% improvement?

It's an old argument because some people don't understand simple math, so it needs to be repeated.

At least with the Nissan diesel you're getting enough power from the diesel to see its other advantages, like towing and torque, come into play vs a good gas engine.

Well, both of you are wrong in all honesty. Prices change, up and down, fast and slow, and differ by region. So the math isn't simple as the math worked with prices were high, but of course now.......

You don't have to know the resale value of the Ecodiesel to know it will be higher than it's HEMI counterpart. The resale of all diesels from other brands that I can think of command higher resale prices than their gas counterpart. The issue is knowing if the higher resale really came out on top. That's a different issue.

I did the math for my region so your numbers might vary.

Diesel models ALWAYS get higher resale value than the comparable gas model. Be it a compact car or the 2500 trucks. Its just a nature of the beast. You pay more for a Camaro SS over a Camaro V6 but you dont loose that $7500 (1SS compared to the 1LT) difference the second you drive it off the lot so why do people insist that in this situation?

Once again, read why I typed. I said if you do any type of light towing the diesel is amazing. There are lots of comparos out there where they compare it to a V8 and it always wins out thanks to the great MPG and the instant torque. Plus, it has a max towing of 9200 pounds (the most common GM truck with the 5.3 and 3.42 2WD is 9800!!!!). Its not like it can only haul around 4000. Its a very capable truck engine.

Man if you don't like the Diesel option in the 1/2 ton trucks, that is fine with us, but man don't try to convince everybody else about how bad a buy it is, people like Diesel pickups for other uses, other than the MPG of the truck.:rolleyes:

I have a funny feeling they simply certified the truck for the lighter weight Quad Cab and reached the number with minimal changes.

Automakers are not forced to certify each individual cab/bed combo.

I like the concept of a diesel half ton, but only in limited applications and I think the diesel Ram is using isn't ideal for the application. IMO the Cummins in the new Nissan makes a lot more sense.

I agree that the new Titan is pretty sweet in the power train department but let's wait and see what happens.

Can you get a regular cab, short box, 4x2 Ram with the Ecodiesel? Wouldn't that get better fuel economy than a quad cab?

It doesn't appear that combination is possible. The regular cab configuration is only offered on Tradesman, Express, Sport, SLT, and Big Horn/Lone Star trims, and none of those offer the EcoDiesel engine option unless Quad or Crew Cab is specified.

There is a gasoline HFE model in the Ram 1500 lineup. It's a regular cab, short box, 4x2 truck with the same feature set as Tradesman plus an auto start-stop system, tonneau cover, and tweaks to the powertrain control software.
