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.

This is how GM is hiding new Chevy Volt in public

General Motors is letting the public know that, well, it's not about to let the public know anything else about the next-generation Chevrolet Volt. But the automaker is willing to talk about its camouflaging process for upcoming versions of the extended-range plug-in. So it's a half-hearted secret, at best. GM actually has a "camouflage engineer" charged with creating ways to disguise the styling of new vehicles. In the Volt's case, the company is applying black and white swirly color patterns on top of the materials, such as plastics, vinyl and foam, that are used liberally across the body. It's all part of a teaser campaign that started last month with pictures of part the 2016 Volt. Earlier this month, GM said it was keeping track of Volt drivers' habits as it works on the next-gen model. The company noted that more than four out of five trips are being made in all-electric driving mode, and that 60 percent of Volt owners use a plain-old 100-volt outlet to recharge their cars. The car is slated to make its global debut at Detroit's North American International Auto Show next January, and the early word is that performance and all-electric range will be improved (we should hope so). The car will also be sleeker. By how much, we can't tell yet, because of those darn swirly patterns. GM's got more non-details in its press release below. Engineers charged with hiding styling while vehicle testing proceeds in public DETROIT – The styling of the next-generation Chevrolet Volt is one of the automotive world's best-kept secrets. Keeping customers and media eager to see the successor to the groundbreaking original at bay until the new Volt debuts at the North American International Auto Show in Detroit in January is tricky business. First, it is engineers, not designers, who are charged with creating camouflage that balances styling secrecy with the need to validate the Volt and its systems in public. "If it were up to me it would be a shoebox driving down the road," said Lionel Perkins, GM camouflage engineer. "The design team wants us to cover more of the vehicle and the engineering team needs to have enough of the vehicle's weight and aero exposed so that the tests in the development process are consistent with the product that will come to market." The engineers responsible for the "cool" designs covering the car might deserve style points but their efforts are intended strictly to hide the metal beneath.

2015 Chevy Silverado, GMC Sierra recalled for steering issues

DETROIT — General Motors Co is recalling more than 1 million pickup trucks and sport utility vehicles in the United States due to issues with a temporary loss of power steering, the National Highway Traffic Safety Administration said. The recall is for 2015 models. They are: the Chevy Silverado 1500, Suburban and Tahoe, GMC Sierra 1500, Yukon and Yukon XL and Cadillac Escalade. The problem may cause difficulty steering the vehicle, especially at low speeds, increasing the risk of a crash, the auto safety regulator said in a document dated Sept. 12. The document did not highlight any reports of accidents and injuries, because of the power steering issue. GM dealers will update the power steering module software, free of charge for owners of the affected vehicles. In 2014, the No.1 U.S. automaker had recalled nearly 800,000 pickup trucks worldwide because of the same problem. GM did not immediately respond to a request for comment.Related Video:
