2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.

Coronavirus shakes up America's truck market: GM outselling Ford and Ram

FCA, Ford and General Motors joined the rest of the U.S. auto industry in taking heavy volume hits due to coronavirus-related shortages of both cars and customers. The saying goes that a rising tide lifts all boats; it stands to reason, then, that a falling one would have the opposite effect.  However, as we learned Thursday, the automotive market can behave in unpredictable ways. While the F-Series remained the best-selling nameplate in Q1, GM's full-size trucks are now outselling Ford's again for the first time in years, and with this upward thrust from the General, FCA's Ram was unceremoniously booted out of a hard-earned second place.  While late-March sales declines hit just about every major automaker in one way or another, the model-by-model results weren't nearly so uniform. And because the market tends to be a zero-sum game, for every winner, there generally has to be a loser.  In this case, that winner was GM, and its rise had to come at the expense of another automaker, in this case, Ford. F-Series sales dropped 13.1 percent in the first quarter of 2020, while sales of GM's full-sized Silverado and Sierra surged nearly 28% in the same period. FCA's Ram lineup managed a steady-as-she-goes 7% increase. All-in, GM finished the quarter with 197,743 full-size trucks sold to Ford's 186,562. Here's the full breakdown: Ford F-Series: 186,562  Chevrolet Silverado*: 144,734 Ram P/U: 128,805 GMC Sierra: 53,009 *includes 1,036 Medium Duty sales Things are a but murkier in the midsize segment, where the Chevy Colorado slipped 36% to just 21,430 units sold — just a few hundred better than the slow-selling Ford Ranger's Q1 numbers. The GMC Canyon experienced an almost identical slide, finishing the quarter with just 4,483 units sold. For perspective, Jeep sold more than 15,000 Gladiators and Toyota's midsize Tacoma slipped less than 8%, finishing the quarter with nearly 54,000 sales.  We suspect this discrepancy in full- and mid-size truck sales comes from shifting incentives. Ford, GM and FCA would like to keep selling bigger trucks because there's far more profit margin built into their list prices. Even with tens of thousands of dollars in manufacturer money on the hood, big trucks still make money.  Since these automakers report quarterly, we won't get another good look at these numbers until July, but if you thought that 2019 represented the new normal for U.S. auto sales, well, think again.

2021 Chevy Tahoe, GMC Yukon fuel economy and towing capacities go official

Most of the puzzle pieces have fallen into place with GM’s new full-size SUVs, but today we have fuel economy and towing to add to the picture. Numbers for the standard 5.3-liter V8 and upgrade 6.2-liter V8 are out, but GM has held back on the 3.0-liter turbodiesel inline-six for the time being. Those numbers are most likely not ready yet. Minor improvements and decreases are seen throughout the Tahoe/Suburban and Yukon/Yukon XL lineup. Because there are so many variants, weÂ’re going to just lay them out below for you. 5.3-liter V8 2021 Tahoe/Yukon 2WD: 16/20/18 2021 Tahoe/Yukon 4WD: 16/20/18 2021 Suburban/Yukon XL 2WD: 16/20/18 2021 Suburban/Yukon XL 4WD: 15/19/17 6.2-liter V8 2021 Tahoe/Yukon 2WD: 15/20/17 2021 Tahoe/Yukon 4WD: 14/19/16 2021 Suburban/Yukon XL 2WD: 15/20/17 2021 Suburban/Yukon XL 4WD: 14/19/16 As you can see, there isnÂ’t a whole lot of difference between two-wheel drive and four-wheel drive options. You can eke out an extra mpg here and there, but itÂ’s a penalty weÂ’d be happy to live with to have four-wheel traction. The biggest loser in all of this is highway mpg. Chevy has made the trucks bigger and added weight with the independent rear suspension, causing a decrease in fuel economy. For example, a 2020 Tahoe with the 6.2-liter V8 and four-wheel drive is rated at 14/22/17. The 2021 truck drops 3 mpg on the highway and 1 mpg in the combined rating. There are improvements to be found, though. A 2020 Suburban with the 5.3-liter V8 and four-wheel drive is rated 14/21/16. Fuel economy in the city goes up 1 mpg, but you lose 2 mpg on the highway and 1 mpg in the combined rating. ThereÂ’s a bit of give and take here, but at least a slight increase in city mpg has accompanied the greater loss in highway fuel economy. 2021-chevy-tahoe-chicago-01 View 12 Photos As for towing, the Tahoe/Yukon with the 5.3-liter V8 and two-wheel drive has a new 7,900-pound capacity, and the four-wheel drive model is rated at 7,700 pounds. Respectively, those are the best figures youÂ’ll get with the standard towing capacity. Opt for the maximum towing package, and the Tahoe/Yukon capacities go up to 8,400 pounds (two-wheel drive) and 8,200 pounds (four-wheel drive). The numbers all take slight cuts when you go for the 6.2-liter V8. Both the Suburban and Yukon XL offer similar or identical towing figures as their shorter counterparts do.
