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.

GM hard at work on Chevy Silverado and GMC Sierra PHEV pickups

Autoweek heard from sources at General Motors and Ford about how each automaker is addressing the dip in EV enthusiasm and sales. At General Motors, AW reports, "plug-in hybrid versions of the Chevrolet Silverado and GMC Sierra are headed to market, in a hurry." The sources gave no timeline for when the trucks might appear. GM CEO Mary Barra told analysts during GM's Q4 2023 earnings call, "Let me be clear, GM remains committed to eliminating tailpipe emissions from our light-duty vehicles by 2035, but in the interim, deploying plug-in technology in strategic segments will deliver some of the environmental benefits of EVs as the nation continues to build its charging infrastructure."  It's too soon to predict how the Chevy Silverado EV and GMC Sierra EV will fare on the market, the Silverado EV Work Truck still the only one available to customers. It might be better for GM if they're not too popular at first, the automaker's cautious EV production ramp-up and recent software setbacks responsible for some still-healthy reservation rolls. Barra said the company plans to build between 200,000 and 300,000 EVs, this year, which would clear that backlog. Heading into the end of February, with the Chevy Bolt out of the picture and additional EV pickup production pushed to 2025, our Spidey senses feel those are optimistic numbers. The Chevy Bolt was the third-best-selling EV in the U.S. last year, at 62,044 units. GM didn't have another vehicle in the top ten. Furthermore, the combined sales of every EV in the top ten after the Bolt — seven models from six manufacturers — is only just over 200,000 units. The Blazer EV and Equinox EV could make it happen, but there's no way Chevy wants to rush those, the Blazer EV still in software purgatory.   The report speaks of collateral damage, GM said to have canceled an electric pickup sized below the Ford Maverick and Hyundai Santa Cruz. Automotive News said it saw the truck in January 2023, describing it as a futuristic two-door with a low roof and a 4.5-foot cargo bed. A new full-size van program supposedly got the axe as well, eliminating the plan to put a new Chevy Express and GMC Savana on a Brightdrop EV chassis. Over at Ford, AW says its sources mentioned another canceled midsizer; Ford's apparently stopped working on an EV pickup sized a bit below the Nissan Frontier.

Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.
