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.

GM’s Charlie Wilson was right: Stronger regulations can help U.S. automakers

Charlie Wilson had been the president and CEO of General Motors before being nominated to become secretary of defense by Dwight Eisenhower. During his Senate confirmation hearings, he controversially said, "For years I thought what was good for our country was good for General Motors, and vice versa." And he was right. While car companies aren't necessarily the most progressive when it comes to things that might have the slightest possibility of political blowback, General Motors should be credited for doing something absolutely forthright in this regard with its announcement that it wants the federal U.S. government not to squash the California Air Resources Board's emissions requirements but to actually create a 50-state "National Zero Emissions Vehicle" program that, in the words of Mark Reuss, executive vice president and president, Global Product Group and Cadillac, "will drive the scale and infrastructure investments needed to allow the U.S. to lead the way to a zero emission future." Filing comments to the Safer Affordable Fuel-Efficient Vehicles Rule for Model Years 2021-2026 Passenger Cars and Light Trucks is one thing. But a graphic the company developed for this announcement — shown above — is something else entirely, something that is absolutely credible, creative and clever. There is a photo of a Chevrolet Bolt EV driving along a highway, which seems to be in Marin County (based on the blurred San Francisco skyline in the background). Text on the photo states: "It's Time for American Leadership in Zero Emissions Vehicles." It seems to say, in effect, "If we want to make America great again, then we're going to do it by leading in technology, not by retreating behind weakened regulations." General Motors understands that the auto market is globally competitive, and if U.S.-based companies are going to be in the game, then they'd better be able to out-innovate the companies based elsewhere, where emissions and economy standards are not being weakened.

The Hummer EV Edition 1 is sold out and it'll be years before other trims arrive

When the 2022 GMC Hummer EV was revealed, GMC noted that there would be lower trims available. The company has since provided a few more details on those lower trims, which is helpful to know now that the only trim on sale next year, the Edition 1, was sold out in a scant 10 minutes. However, it's going to be a long time before they're all available.  The entry-level GMC Hummer EV is the EV2. This is the model that will start at $79,995, and unlike the Edition 1, it gets just two motors, one for each end of the truck, each with electronically locking differentials. Output is down to 625 horsepower and a torque rating of 7,400 pound-feet. Note that this and all other reported torque numbers are after the torque multiplication by the single-speed transmissions, hence the extremely high numbers. The company hasn't given torque numbers at the motors, which would be more comparable to other electric cars. Range is also reduced to 250 miles, probably due to a smaller battery pack. Fast charging is also restricted to 400-volt charging, so it won't be as fast as the higher trim models. The removable roof panels, retractable rear window, MultiPro tailgate, Super Cruise and 35-inch tires are standard. This model only gets fixed steel suspension and two-wheel steering. The EV2 will be the last of the trim levels to go on sale, with a target of spring 2024. Yes, as in 3.5 years from now.  The next level is the EV2X, which will be available a year earlier in the spring of 2023. It gets the same powertrain as the EV2, but adds 800-volt fast charging and a 300-mile range. It also gets the adaptive air suspension and four-wheel steering, plus the associated party tricks of Crab Mode and Extract Mode. This model costs $89,995. The earliest Hummer EV that isn't an Edition 1 and therefore not yet sold out will be the EV3X, the entry-level three-motor model. It goes on sale in the fall of 2022 at a price of $99,995. It's not quite as potent as the Edition 1, though, with an output of 800 horsepower and 9,500 pound-feet of torque. It also lacks the "Watts to Freedom (WTF)" launch control feature. But it does get torque-vectoring with the dual rear motors, which can also lock their speeds to be equal like with the mechanical locking differential at the front. The EV3X's range is 300 miles like the EV2X.  As for the Edition 1, it started $112,595 before it was sold out. Customers are to expect them in fall 2021.
