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.

2020 Chevy Trax and Buick Encore spied testing

We just recently saw a little crossover SUV from General Motors being tested, and we weren't positive what brand it belonged to. We narrowed it down to Chevy or GMC, but we're feeling more confident that it's a GMC now, since both the next generation Chevy Trax and Buick Encore subcompact crossover SUVs have been spied testing together. Of the two, the Chevy has the more radically different sheet metal. It ditches the somewhat frumpy, lumpy shape of the current Trax for a body inspired by the bigger Chevy Blazer. The roofline has sharp corners, and the hood is wide and flat. The front fascia, though obscured, shows the most connection to the bigger crossover. It has the same split headlight configuration, and it looks as though the grille takes up a sizable section of the fascia. View 7 Photos The Buick Encore on the other hand looks evolutionary in design. The body still has plenty of curves, and the distinctive, sharply rising window sill are all hallmarks of the current Encore design. The headlights and grille are similar, too, though the grille appears to be slightly updated to fit in with the Enclave and Regal. It's understandable that Buick might want to play it safe with the new Encore, since the model is Buick's best seller, selling about 23,000 units in the last quarter, nearly twice that of the next best performer, the Enclave. Since this is the first time we've seen these little crossovers, we expect it will still be a year or two before we get to see them fully revealed. They will probably continue to use small-displacement turbocharged four-cylinder engines with either front- or all-wheel drive. Related Video:
