Leak reveals GM's 2017 heavy duty diesel trucks to get 910 lb-ft of torque [UPDATE]

UPDATE: Chevrolet officially announced specs for the 2017 Silverado HD and the rumors were true. The truck's new Duramax 6.6-liter turbo-diesel V8 puts out 445 horsepower and 910 pound-feet of torque. Chevrolet says the new motor produces 19 percent more torque and 12 percent more horsepower, while producing 35 percent fewer emissions. Overall, the new engine is a big improvement over the current motor, which generates 397 horsepower and 765 pound-feet of torque. According to Truck Trend, GM's newest heavy duty pickup trucks will pick up quite a bit more power and torque. The publication spotted a recent GM Powertrain ordering catalog that had the engine specs for the 2017 model year and managed to get some screenshots before the catalog was taken down, and they can be viewed here. The screenshots revealed that the 6.6-liter turbodiesel V8 powering the Silverado and Sierra heavy duty models will boast 445 horsepower and 910 lb-ft of torque. This is a substantial gain over the current models' 397 horsepower and 765 lb-ft of torque, and as Truck Trend points out, it exceeds the Ford Super Duty line's horsepower output of 440, but comes short of the 925 lb-ft rating. Truck Trend credits part of this output gain to the new intake system GM will introduce on the 2017 heavy duties. The intake gets 60 percent of its air from a scoop on the hood, with the other 40 percent coming from behind one of the front fenders. GM doesn't reveal horsepower figures in the press release about the scoop, but it does say the cooler air helps with maintaining the engine's output, and that the scoop does produce a ram-air affect, providing more air at speed. As we know, more air plus more fuel equals more power, but there's likely more to the power increase in this engine than only the intake.

Best cars for snow and ice in 2023 and 2024

What's the best car for snow? The real answer is "the one with winter tires." What do we mean by that? You could have the finest, most advanced all-wheel-drive system or four-wheel drive in the world, but if you're running all-seasons (the spork of tires), your fancy four-wheeler won't matter much. The odds are, any vehicle on the road running good winter tires will probably perform adequately in slippery, slushy and/or snowy road conditions. (Here's a more complete explanation of why winter tires are totally worth it). In other words, you don't really need any of the cars on this list. With a set of winter tires, countless others will do the job, and even these will be at their best with proper rubber. You can find a variety of winter tires for your car here at Tire Rack. Keep in mind that you will need a full set of four snow tires for safety and performance, no matter what you're driving. The days of your dad putting just two snows on the family truckster to get it moving in a straight line are long gone. Don't get us wrong, getting a car that performs well in snow and ice is still a worthy criteria for car buyers. According to the U.S. Transportation Department, 70% of Americans live in places that get snow and ice. And much of the country has been blasted with arctic air for much of the new year. So let's look at the cars. First, we're highlighting choices for a variety of buyers and price points. Second, we're not just considering snow; we're considering general wintery conditions people will experience driving to work or school. As such, these are all choices with advanced all-wheel-drive systems, usually with "torque-vectoring" systems that not only automatically shunt power front and back, but side to side between the rear axles. Most have extra ground clearance for getting through deep snow, and we prefer those vehicles with more responsive steering, throttles and transmissions that provide a greater sense of vehicle control in slippery conditions.    Acura RDX Read our Acura RDX Review Acura's Super-Handling All-Wheel Drive system was one of the first to offer torque-vectoring, and besides often being touted for its ability to greatly enhanced dry-road handling, its benefits in the slick stuff can be profound. It's actually surprising that Acura hasn't leaned into this capability further by offering more rugged versions of its vehicles.

Chevy rolls out Silverado HD High Country

It's been a good week for heavy-duty truck buyers. First, Ram revealed the Black Package for its HD trucks, then it rolled out its new Power Wagon, and now Chevy's getting in on the action with its Silverado High Country HD. Okay, so it may not pack quite the attitude of Ram's latest 2500-series offerings, but the High Country HD will come as a welcome addition to the Chevy Trucks range to those looking to pull their horse, boat or other trailer without skimping on creature comforts.
Rolled out a little under a year ago, the High Country trim is Chevy's answer to the likes of the GMC Denali, Ford King Ranch and Ram Longhorn. It has until now only been offered on the light duty, 1500-series Silverado, but now extends to the 2500 and 3500-series HD models, as well.
So what sets a High Country pickup apart from lesser Chevy trucks? You'll be able to pick it out based on its chrome horizontal grille, body-color bumpers, 6-inch tubular side steps, 20-inch chrome wheels (18-inch on the 3500 and 17-inch on the dualie) and, of course, plenty of special badging. But it's inside where the High Country makes its mark, with a cabin decked out in saddle brown perforated leather, seats that are both heated and cooled, eight-inch touchscreen with full MyLink suite, Bose audio and park assist functions front and rear to keep those color-keyed bumpers looking fresh. (Though Chevy hasn't yet showed us the interior of the HD model, it'll presumably look mostly the same as the cab in the 1500 High Country in the gallery below.)
