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.

2015 Ford F-Series Super Duty Power Stroke

What weighs 30,000 pounds? Big Ben's Westminster bell. A navy ship anchor. Or as we found out during our first drive program for the 2015 Ford F-Series Super Duty, seven pallets of cinder blocks loaded onto a dual-axle gooseneck trailer. The test was part of a raft of towing demonstrations that showcased the new Super Duty's impressive tug capacity, which maxes out at 32,100 pounds. That's 1,200 more than its nearest rival, the Ram 3500, when equipped with its upgraded 6.7-liter Power Stroke diesel V8. Such is the heavy-duty pickup truck business, a diesel-fueled game of one-upmanship with only three players: Ford, Chevrolet/GMC and Ram. And in this game, the one with the most torque wins.
Until 2014, Ford was the one to beat, with its 6.7-liter Power Stroke diesel bringing 400 hp and a massive 800 lb-ft of torque to the table. Then last year, Ram did exactly that, serving Ford with a beefed-up Cummins turbodiesel inline-six in its freshened Ram Heavy Duty truck line with 385 hp and 850 lb-ft of torque, enabling it to tow up to 30,000 pounds. But Ford claims it had designed its engine to be relatively easy to upgrade when the time called for it, so for 2015, Ford bolted a larger turbo to the Power Stroke, bringing output to an insane 440 hp and 860 lb-ft of twist, all without reducing fuel efficiency. Maximum tow capacity rises from 24,700 lbs to an incredible 31,200 lbs for the F-450 dually.
As for GM's HDs? They lag behind the lot with their 6.6-liter Duramax V-8, producing 397 hp and 765 lb-ft of torque. Yeah, you know things are serious when the trucks with 765 lb-ft are the knock-kneed wimps of the lot.

Watch the Hennessey Ford GT makes its record run at Texas Mile

We said they'd probably be out with an official video, we did not lie. The Hennessey-powered camouflage Ford GT sat at one end of the runway at the Texas Mile sitting still. At the other end of the runway it had broken its own speed record, the twin-turbo 5.7-liter V8 pushing the aerodynamic supercar up to 267.6 miles per hour, a 4.3-mph improvement over the old mark.
There's not much in the video you haven't already seen, this just makes it official. That said, who doesn't want to see a twin-turbo Ford GT set an incredible speed record? You can watch it below.
