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.

2016 Chevy Colorado Duramax makes 369 lb-ft for $3,730 premium

Since announcing the new Chevrolet Colorado in late 2013, there has been absolutely no secret that the 2.8-liter Duramax diesel would wind up under the hood of the midsize pickup truck for the 2016 model year. It has been a long wait for those wanting the oil-burner, but thankfully, the anticipation is nearly at an end. Chevy is finally officially unleashing details about the four-cylinder, which churns out 181 horsepower and 369 pound-feet of torque. The diesel is available in both LT and Z71 Crew Cab trims, and there's the choice of two- or four-wheel drive. All come with a six-speed automatic gearbox with a standard automatic-locking rear differential. An electronically controlled two-speed transfer case comes on four-wheel drive models, as well. The Z82 trailering package also arrives on all of the Duramax pickups and includes an exclusive integrated trailer brake controller. The first shipment of diesels arrives at dealers this fall with a price of $3,730 on top of a comparably equipped version with the 3.6-liter V6. Customers opting for the Duramax are getting more capability from the Colorado. With a 7,700-pound tow rating on two-wheel drive examples (7,600 pounds with four-wheel drive), drivers can haul 600-700 pounds more behind the truck than its petrol V6 counterpart. Fuel economy numbers haven't been announced yet, but are expected to top the gasoline versions. The engine is also B20 bio-diesel compatible. Beyond being just a good hauler, Chevy is throwing cutting-edge tech into these models. For example, this is the company's first application of a Centrifugal Pendulum Vibration Absorber on the transmission's torque converter. The device is a dampener that cancels out torsional vibration from the engine for a more comfortable ride for occupants. There's also a driver selectable exhaust brake system that uses engine compression to help slow down the truck and reduce brake wear. You can read more about the nuts and bolts of the diesel in Chevy's press release below. Chevrolet Introduces Colorado Duramax Diesel All-new turbo-diesel expands lineup with unparalleled capability, efficiency DETROIT – The fastest-selling truck in the market now offers an available turbo-diesel engine. The 2016 Chevrolet Colorado Duramax diesel takes midsize truck capability and efficiency to unprecedented levels.

Chevy confirms Corvette Stingray Convertible for Geneva

Want proof that General Motors has increased global ambitions for its 2014 Chevrolet Corvette Stingray? It's staging the world premiere of the model's convertible variant at the Geneva Motor Show early next month.
As previously rumored, the droptop rendered above will debut at the Swiss show, making its first appearance anywhere on March 5. According to Susan Docherty, president and managing director of Chevrolet, the location makes sense because Corvette "...is an icon that has long been recognized and admired even in countries where it's never officially been offered."
While neither Chevrolet nor the Corvette has a major sales presence in Switzerland, the Bowtie's European headquarters is located in Zurich (about three hours to the northeast of Geneva) and GM has made it clear that it wants to build the Chevrolet brand up across Europe.
