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.

2014 Chevrolet Silverado and GMC Sierra show all their sides in Detroit

There could hardly be more riding on the next-generation General Motors full-size pickup trucks, so the automaker has wisely made sure to have a selection of different models on hand at the Detroit Auto Show to show off. The 2014 Chevrolet Silverado and 2014 GMC Sierra were both officially introduced last month at a stand-alone reveal, and now they'll be on display for the public to see in various body configurations and trim levels.
The Silverado LTZ Crew Cab and Sierra SLE Extended Cab are aimed at providing more of a high-end pickup experience, while the Silverado LT Z71 Extended Cab and Sierra SLT Z71 Crew Cab should have off-road fans scouting out their favorite trails. The crew cab trucks won't go into production until sometime during the second quarter of this year - with other bodystyles coming later in the year - but we have plenty of live images from Detroit for you to enjoy.

J.D. Power study identifies top seats for your tush

File under News your fanny can use: The seating systems in the Ford Escape and Edge, the Audi A3, Chevrolet Cruze, Kia Cadenza, Porsche Cayenne and Toyota Tundra received top marks in a new J.D. Power study on seating and seat belt quality and satisfaction. The J.D. Power 2017 Seat Quality and Satisfaction Study asked more than 77,000 new owners and lessees of 2017 model-year cars and light trucks to rate their vehicle's seats and seat belts within the first 90 days of taking ownership. The survey is broken up into seven vehicle segments and scored on total seat problems per 100 within each segment, with awards presented to the seating system supplier. Canadian auto supplier Magna won three of seven first-place awards for its seating systems in the A3, Escape and Edge. Ireland-based Adient got top marks for its seats in the Cadenza and Cayenne. Lear Corp. won for the Cruze, and Avanzar Interior Technologies scored highest for seats in the Tundra. J.D. Power says its study is intended for automakers and suppliers with quality and satisfaction information to be used in developing and marketing seating systems. "But the results are just as interesting to a consumer audience," the company says. "After all, some drivers spend a considerable amount of time behind the wheel, and it's helpful to know which vehicles offer the most comfortable seats for those long commutes." Ain't that the truth. Ford was the only automaker whose seat systems, both manufactured by Magna, received top honors in two segments: the Escape for mass-market compact SUV and the Edge for mass-market midsize/large SUV. J.D. Power says it used 22 attributes to measure seat quality, three measures of seat belt quality and 12 to measure satisfaction. Awards were presented to the seating suppliers.
