Diesel details: Comparing Ram 1500 EcoDiesel, Chevy Silverado Duramax, Ford F-150 Powerstroke

With specifications for the 2019 Ford F-150 Power Stroke diesel already out, and the details on the 2020 Ram 1500 EcoDiesel and Chevy Silverado Duramax (and its GMC Sierra twin) trickling out, we felt it was a good time to start comparing the full-size trucks' light-duty diesels. Bear in mind, we've only driven one of these new diesel trucks, so we'll be sticking to numbers for now. Some numbers haven't been announced yet, either, but stay tuned, because we'll be updating this post with additional specifications as they become available. And if you want to compare any other versions of these trucks with other vehicles, be sure to check out our comparison tool. Now let's start comparing, starting with our big chart of numbers below. As we can plainly see, these trucks are quite closely matched. Each one has six cylinders, a displacement of 3.0 liters and a turbocharger to boost it. The output of each is somewhat close, too. The Ram 1500 EcoDiesel is the torque king at 480 pound-feet, 20 more than the GM trucks and 40 more than the Ford. The GM trucks win on power, though, with 277 ponies, 17 more than the Ram, and 27 more than the Ford. GM does report that you get their trucks' peak 460 pound-feet of torque from 1,500 rpm to 3,000 rpm, whereas the others only report peak torque at a particular point in the rev band, but all of these trucks should have wide, flat torque curves as you would expect from modern turbodiesels. 2020 Ram 1500 EcoDiesel View 8 Photos Engine output is only one part of the truck performance equation. We also have towing and payload capacity, as well as fuel economy. With towing, the Ram 1500 is the current leader with a maximum capacity of 12,560 pounds. That tops the Ford F-150's 11,400-pound tow rating by well over 1,000 pounds. The F-150 can carry 2,020 pounds in its bed, but we don't know yet whether that's better or worse than the Ram or the GM trucks. We also don't have numbers for the GM trucks' towing capacities. View 9 Photos As for fuel economy, the Ford F-150 manages a thoroughly impressive 22 mpg in the city and 30 on the highway with two-wheel drive. Choosing four-wheel drive drops those numbers to 20 and 25 respectively. The fuel economy numbers for the Ram, Chevy and GMC haven't been revealed yet, but for some comparison, we can look at the old Ram EcoDiesel. That truck's best fuel economy was 20 in the city and 27 on the highway with two-wheel drive.

Next Lincoln Navigator to drop V8 in favor of V6, but Ford Expedition might get both

A great many buyers fled from full-size body-on-frame SUVs to car-based crossovers in large measure to save fuel. But that doesn't mean there's still not a buying audience for more traditional truck-based utility vehicles, and those consumers doubtlessly wouldn't mind saving some dollars at the pump, too. According to Motor Trend, those shoppers might be in luck.
That's because the magazine has confirmed that Ford isn't walking away from the full-size SUV segment, and it's poised to do something about its offerings' economy ratings, too. According to MT, global Lincoln director Matt VanDyke has hinted that the next Navigator may drop two cylinders and go with a V6 model - the current model gets just 14 miles per gallon in the city and 20 on the highway from its 5.4-liter V8. The obvious fitment would be Ford's 3.5-liter twin-turbo EcoBoost V6, an engine that has spread like kudzu throughout the rest of the Blue Oval's large vehicle lineup.
Downsized turbocharged engines like Ford's EcoBoost franchise have come under fire as of late for not delivering their EPA fuel economy ratings, but their benefits extend beyond consumption - the 3.5L offers superior power and a better torque curve than the naturally aspirated V8. MT also suggests that Ford's 3.7-liter V6 could form the base engine for the next Navi - it has similar horsepower but a lot less torque than the current 5.4L. That may be less of a problem with the next generation tipped to go on a diet, which could level the playing field somewhat.

2018 Ford F-150 Powerstroke vs. 2018 Ram 1500 EcoDiesel: comparing the specs

Now that Ford has finally released specifications for its diesel Ford F-150, we can finally see how it stacks up against its sole competition, the Ram 1500 EcoDiesel. Naturally, since we haven't driven the new diesel F-150, we can't tell you which is better on the road, but there are interesting things we can glean from the numbers. Compare these and other potential new vehicle purchases using our tool. For one thing, the two trucks are extremely similar from a powertrain perspective. Both trucks use a turbocharged 3.0-liter V6 diesel, with the Ford using a 10-speed automatic, and the Ram using an 8-speed automatic. The Powerstroke engine is built in the U.K. but specifically tuned by Ford for American pickup truck duty. It is also is related to the diesel V6 used by Jaguar and Land Rover. The Ram 1500's engine is made by VM Motori. Only 10 horsepower and 20 pound-feet of torque separate the two, with the Ford getting the slight advantage. The Ford also produces its horsepower and torque slightly sooner than the Ram. Peak power in the Ford comes at 3,250 rpm compared to 3,600 rpm in the Ram, and peak torque arrives at 1,750 rpm in the Ford, and 2,000 rpm in the Ram. View 9 Photos More significant differences become apparent in the payload and towing area, both of which put the Ford at an advantage. The F-150 Powerstroke can carry 2,020 pounds of cargo, or tow 11,400 pounds. The Ram EcoDiesel, depending on configuration, can carry 1,100 to 1,600 pounds of cargo, and tow between 7,560 and 9,210 pounds. Fuel economy might go to the Ford if it hits the company's target of 30 mpg highway. That would beat the Ram's 27 mpg highway. We don't know what Ford's target city mpg is, but the Ram manages 20 in town with two-wheel drive. Four-wheel drive drops the city rating to 19 mpg. View 6 Photos The biggest decider between the trucks might be cost. Ford is only offering its diesel engine on higher end trims, which means that the cheapest diesel F-150 starts at $46,315. That's for a two-wheel drive Lariat extended cab with a 6.5-foot bed. Ram on the other hand, offers the diesel in everything from its ultra-bare-bones Tradesman pickup, allowing for a base price of just $28,585, up to the fancy Laramie Longhorn and Limited trims. Ram's diesel is also available with all cab variants, while Ford's is only offered in extended- and double-cab body styles.
