GM's fullsize SUVs boost highway mileage by nearly 10 percent

We met the redesigned 2015 versions of the Chevrolet Suburban and Tahoe, and the GMC Yukon and Yukon XL at the 2013 LA Auto Show. Improved gas mileage numbers have been announced to go along with the improved exteriors and interiors, with city mileage improving by seven percent and highway mileage going up by nearly ten percent; you'll now get 16 miles per gallon in the city and 23 on the highway.
The only applies to models with the 5.3-liter engine, though, not the premium Yukon Denali and Yukon XL Denali SUVs with the 6.2-liter motor. Still, the 5.3 gets you more power than previously, with 355 horsepower and 383 pound-feet of torque underfoot, on top of the improved fuel economy numbers. The 6.2-liter sticks with official mpg ratings of 15 highway, 21 city. There's a brief press release below with words straight from the horse's mouth.

GMC Hummer EV pickup reveal postponed

We’re pretty excited about the all-electric Hummer pickup coming from the GMC brand. GM is too, enough to spend Super Bowl money on an ad teasing it. Today, we received an update from GM about the Hummer EV, with good news and bad news. The bad news: GM has announced that it is postponing the May 20 reveal for the Hummer. With the coronavirus throwing the proverbial wrench into a number of vehicle operations, including reveals, we canÂ’t say weÂ’re surprised at all. The good news, GM assures us, is that development continues “undeterred.” GM understandably hasnÂ’t provided a new debut date for the GMC Hummer EV, but it did provide us with the new short teaser video above. WeÂ’ve seen other details in previous teasers, as well. We were lucky enough to see the Hummer EV in person last month just before the pandemic began causing the world to grind to a halt. At GMÂ’s EV Day at its Warren, Mich., campus, the Hummer pickupÂ’s exterior was on full display. ItÂ’s a big, off-road-ready pickup complete with giant all-terrain rubber and tow hooks. It features removable roof panels for access to the open sky, which appears to be depicted in the teaser above. It features sail panels behind the C-pillars, similar to those on the Chevy Avalanche and Honda Ridgeline. Its bed was concealed with a tonneau cover, but it sported GMCÂ’s MultiPro tailgate that we first saw on the Sierra Denali. Interior photos showed a spacious interior with blocky shapes, squared hourglass vents that mirror the look of the taillights and a lunar theme that incorporates the topography of the Sea of Tranquility into things like the floor mats and speaker covers. It also has a large infotainment screen as well as a digital instrument panel. The Hummer pickup will be offered with a number of electric powertrain options, the most powerful of which will provide 1,000 horsepower and a 0-60 mph time of less than three seconds. Like the rest of the next generation of GM EVs, it will use the automakerÂ’s new Ultium modular battery and powertrain technology. While we donÂ’t have further details about a potential reveal date, we also know a Hummer electric SUV based on the pickup will follow at some point. It, too was on display at GMÂ’s EV Day. It looks exactly like the Hummer pickup from the rear doors forward, but with a shorter wheelbase and enclosed cargo area in the rear. It also sported a liftgate-mounted spare.

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.
