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.

Here are all the EVs with 800V charging available in 2024

As technology advances, electric cars are improving their fast-charging times. That means less time spent waiting at a DC public charger when you’re out on the road. While Level 3 chargers used to provide a maximum of 150 kilowatts of power, 350-kW chargers are become more common, making for super-fast charging Â… if your car is capable of taking advantage of it. So how do automakers improve the charging speed of their EV batteries? Some are turning to higher voltage, specifically 800V charging. What's the difference between 800-volt charging and 400-volt charging? So how does 800V charging improve upon the more common 400V EVs? Put simply, the higher the voltage, the less amperage (current) it requires to charge. In other words, with more voltage, you get more wattage (power, aka charge rate) from the same amperage (current). 800V architecture is also more efficient, with less electrical resistance, so it can use thinner cables and smaller, lighter components while needing less cooling. The tradeoff is that it is more costly, and guess who that cost gets passed on to. While automakers don't break down their pricing to show how much more you're paying for that 800V system, you'll just have to evaluate any potential purchases as a whole, and make your decision based on overall pricing of the vehicle. Thankfully, the 800V EVs on sale now are generally ones we like. Now, 800V charging capability doesn't necessarily mean an EV has 800V vehicle architecture. For instance, the GMC Hummer EV and Chevy Silverado EV operate at 400V, but with their dual battery packs, can switch to 800V when charging by temporarily connecting those packs in series. Currently, there are only a handful of EVs available with 800V charging. But if you are going to find yourself taking longer trips in your EV and using DC fast chargers more often, you might want to consider choosing one with this faster charging capability. With that in mind, these are the EVs available with 800V charging, either on sale now or coming in 2024. 800-volt EVs available in 2024 Audi E-Tron GT Chevrolet Silverado EV Genesis GV60 Genesis Electrified G80 Genesis Electrified GV70 GMC Hummer EV Pickup GMC Hummer EV SUV GMC Sierra EV* Hyundai Ioniq 5 Hyundai Ioniq 6 Kia EV6 Kia EV9 Lotus Eletre* Lotus Emeya* Lucid Air Lucid Gravity* Porsche Macan Electric* Porsche Taycan Ram 1500 REV* Tesla Cybertruck *Coming later in 2024 Green Audi Chevrolet Genesis GMC Hyundai Kia Lotus Porsche Tesla Electric Lucid EV charging

2018 GMC Sierra 2500HD All Mountain concept: Nothing stops it in its tracks

Winter may not be the best time for sports cars, but snow and ice can still provide a ton of fun in the right vehicle. The Porsche Macan GTS I had back in January was a riot in the snow, and it was wearing nothing more than a good set of winter tires. What you really need to conquer the frozen north is tracks. These replace wheels with the same sort of equipment that helps tanks and snowmobiles roll over damn near everything in their paths. That's what makes the 2018 GMC Sierra 2500HD All Mountain concept so awesome. That and the 910 pound-feet of torque from the 6.6-liter Duramax turbo diesel V8. The All Mountain concept is set to debut this week in Veil, Colorado, home to ski slopes, log cabins and nearly year-round snow pack. The truck is based off a standard GMC Sierra 2500HD. The turbo-diesel V8 makes 445 horsepower in addition to the mountain of torque. Power is sent to all four corners through an Allison 1000 six-speed automatic. The new treads come courtesy of Mattracks. The 150 Series tracks aren't cheap — well into five figures with installation — but they give you a nice 16-inch surface at each corner. Other changes and add-ons include graphics on the bodywork, a RIGID E-Series 30-inch light bar, LEDs on the wheel well and underbody, Thule snowboard racks, a roll-up tonneau cover and a new speaker system from Kicker. The truck will stay on display in Veil all winter, though a similar concept will be making its way to various auto shows, starting with Los Angeles next week.
