2020 Chevy Silverado HD vs. 2019 Ram, Ford heavy duty trucks: How they compare on paper

Last year was all about the latest in light-duty full-size pickup trucks, so this year, Ram, Ford and Chevy are launching the heavy-duty variants. The first out of the gate is the redesigned 2019 Ram 2500 and 3500 HD, and Ram dropped all the pertinent specs with the reveal. Chevy followed with the new Silverado HD in Chicago, and Ford revealed updates to the Super Duty at the same show. Ford hasn't released details on output, payload capacity, towing capacity or pricing for the updated Super Duty. As such, we'll be comparing the current Super Duty with the all-new Silverado HD and Ram HD. Both Chevy and Ram have revealed full specs for each of their respective trucks, leaving out only pricing, which we've estimated based on the outgoing models. You can see the raw details in the chart below, followed by extra information and analysis. Some things to keep in mind: These specifications cover all versions of the Ram HD, Silverado HD and Super Duty, such as 2500 and 3500 models, and all the way up to F-450. Specifications can vary widely based on engine, drivetrain, cab and bed configurations, so be sure to take a close look at the specific model you're interested in when you get particularly serious about buying. And of course, be sure to check out our car comparison tool if you'd like to look at other trucks on the market. Engines and drivetrains All three of these trucks offer gasoline and diesel engines, but only the Ram has two versions of the diesel. Starting with gas engines, Ram's 6.4-liter V8 has the power advantage with 25 more horsepower than the next-most-potent Super Duty, but the new Silverado HD's 6.6-liter V8 takes the torque crown at 464 pound-feet, nearly 35 more than the other two gas engines. The Ram is also the only one to pair an eight-speed automatic with the gas engine, whereas the Ford and Chevy make do with a six-speed. With diesel engines, horsepower is a weak point for the Ram. The Ram's entry-level turbo 6.7-liter inline-six is the weakest, as the only one with under 900 pound-feet of torque and under 400 horsepower. Even the high-output version only makes 400 horsepower, while the Chevy makes 445 and the Ford 450. But the tables turn with torque, as the Ram makes a best-in-class 1,000 pound-feet followed by the Ford's 935 and the Chevy's 910. Both the Ram and the current Super Duty diesels each get a six-speed automatic, but the new Silverado HD's diesel gets a 10-speed unit.

GM being sued over imploding Bosch fuel pumps in Duramax diesel trucks

Texas-based law firm Hilliard Martinez Gonzalez (HMG) this week filed a class-action lawsuit against General Motors over an alleged issue with Bosch CP4 fuel pumps. The suit claims Bosch designed the CP4 pump to work with European diesel fuel, which is thicker than U.S. diesel. When GM installed that pump in the 6.6-liter Duramax engine used from the 2011 to 2016 model years, the lawsuit claims the thinner U.S. fuel didn't provide enough lubrication, allowing air pockets to form in the fuel pump. That, in turn, allegedly let metal rub against metal inside the pump, causing the pump to eventually disintegrate and "send thousands of metal shards into the fuel injection system and every part of the engine." The Detroit News reported on the most recent lawsuit filed in Michigan's Eastern District Court, but the case is another piece of nationwide legal maneuvering going on since at least last September. Every U.S. truck maker used the Bosch CP4 fuel pump, and HMG originally went after all of them, as well as Bosch. On September 30, 2018, HMG filed a class-action suit in Texas on behalf of eight plaintiffs. The law firm wanted to prosecute the affair under RICO — the Racketeer Influenced and Corrupt Organizations Act — and named 10 defendants: FCA US LLC, FCA North America Holdings, LLC, F/K/A Chrysler Group, Fiat Chrysler Automobiles, N.V., Ford Motor Company, General Motors LLC, Robert Bosch GmbH, Robert Bosch LLC, VM North America, Inc., and VM Motori S.P.A.  The firm filed another suit in Florida on Nov. 2, 2018, against the same 10 defendants, again under the RICO statute, this time on behalf of more than 30 plaintiffs. We don't know how many other suits might have been filed, but the two suits mentioned apparently didn't have legs — the courts dismissed both quickly. So HMG shifted its strategy away from the RICO angle, and focused its efforts on GM, filing suit in California on Nov. 20, 2018. Instead of trying to catch 10 fish with a small net, HMG wants to score one fish with a big net. The results have borne more promise for the plaintiffs. In July this year, a judge in California denied GM's motion to dismiss, noting "the alleged defect is central to the vehicleÂ’s function." This latest suit filed on Aug. 6 in Detroit singles out GM again.  The Bosch CP4 is known to be problematic, however.

Ram shows off its 2019 Heavy Duty trucks in Laramie Longhorn trim

It may not be everyone's bag (baby), but Ram's high-end Laramie Longhorn trim level has proven quite successful for the truck maker. The Southwestern-themed kit has won the Luxury Pickup Truck of Texas award three years in a row, and you know how popular fullsize pickups are in the the great state of Texas. No surprise, then, that the truck is making its debut today at the Houston Auto Show just a week after other trim levels of Ram's 2019 2500 and 3500 Heavy Duty pickup truck line were displayed in Detroit. Like other 2019 Ram HDs, the Laramie Longhorn comes standard with a 6.4-liter gasoline-fueled Hemi V8 sending 410 horsepower and 429 pound-feet of torque through an 8-speed automatic. Two diesel engines are optional, both sourced from Cummins, both displacing 6.7 liters, and both mated up with 6-speed automatic transmissions. The first step up the diesel ladder nets the buyer 370 hp and 850 lb-ft. But the big dog is the High Output inline-six-cylinder diesel with 400 horsepower and a superlative-defying 1,000 lb-ft of torque at just 1,800 rpm. What sets the Laramie Longhorn apart from lesser models are its interior furnishings. It's heavy on full-grain leather, but now boasts a new alligator skin-embossed surface over the center console, instrument panel, seats and door-panel inserts. Warm-hued satin chrome and brushed nickel trim are unique to the Longhorn, as are barn-wood accent pieces. The interior color offerings include a two-tone brown and a black and tan package. Outside, the Laramie Longhorn offers optional RV Match Walnut Brown bumpers and flares for those who want a unified towing experience. Wheels measuring 20 inches in diameter are offered in various finishes, and the badges are inspired by large belt buckles. See for yourself in the image gallery up above. If you find the style appealing, prefer to travel with your vacation home in tow, and don't mind a starting price that's sure to approach $60,000 with the base V8, Ram promises its Heavy Duty haulers will ride better than their Ford or Chevy equivalents due to their five-link coil and air-bag supported suspension systems. Plus, with a max tow rating of 35,100 pounds courtesy of the the Cummins H.O. powertrain, Ram has bragging rights as the baddest truck in town... for now. Related Video:
