GMC Sierra EV Denali Edition 1 teased before tonight's debut

GMC says its Sierra EV Denali Edition 1 battery-electric pickup is "Built to tower above everything you thought an electric truck could be. That’s why itÂ’s the only EV that deserves the name Denali." We will know what the marketing speak means tomorrow (Thursday), when GM's third electric pickup in a year debuts at 5 p.m. Eastern. GMC teased the face of the Ultium-powered Sierra Denali nearly a year ago with an animated rendering. This second teaser on the eve of the debut gives us a better feel for what to expect. The front fascia advertises the product with illuminated GMC lettering at the center of a grille panel defined by an illuminated border. Upside down L-shaped LED lights frame three LED charging status bars. Below those at the bumper edges are what look like four fog lights, two round units above two squared oval units. In back, a glimpse of taillight reminds one of the Hummer EV's spendy rear lights, a Denali badge informing tailgaters what kind of truck they're following. A panoramic glass panel takes up just about the entire roof, save for some sheetmetal at the back where the shark fin antenna rests. Under that roof, one of the seating options will be a ventilated, quilted fabric with "Denali" embroidered in the headrest.  All the other intel must wait another 24 hours. This truck's Chevrolet Silverado EV sibling has been pitched as pricing between $40,000 and $105,000. We've been told the Sierra EV will only come in Denali trim, so expect the feature set and pricing to align more with the Hummer EV, from close to $100,000 once all trims are rolled out to sums well over $100,000. The furnishings could set a new benchmark in glitz for GMC, brand VP Duncan Aldred saying, "We now have an opportunity to evolve SierraÂ’s capabilities and technologies, as afforded by transitioning to an all-electric propulsion while also elevating the luxurious design and comfort associated with Denali." The playbook established so far leads us to believe the Ultium platform will provide a 200-kWh battery and an estimated range of 400 miles, and an output of something like the 664 horsepower and 780 pound-feet of torque in the top Silverado EV trim. Or this limited Edition 1 trim could split the power gap between the Silverado EV and the 1,000-hp Hummer EV.  Reservations open after the debut.

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 to idle Indiana truck plant for two weeks over chip shortage

WASHINGTON —General Motors said Friday it will idle for two weeks in April an assembly plant in Indiana that builds pickup trucks, over ongoing semiconductor chip shortages. The Detroit automaker said it will halt production at its Fort Wayne assembly plant, which builds the Chevrolet Silverado 1500 and GMC Sierra 1500, for two weeks starting April 4. "There is still uncertainty and unpredictability in the semiconductor supply base, and we are actively working with our suppliers to mitigate potential issues moving forward," GM said Friday. The automaker said this is its first semiconductor-related full-size truck production downtime since August. GM noted that overall it has "seen better consistency in semiconductor supply through the first quarter compared to last year as a whole. This has translated into improvement in our production and deliveries during the first three months of the year." GM Chief Executive Officer Mary Barra met with some lawmakers on Capitol Hill this week, including Republican Senator Todd Young of Indiana. GM is backing a bill in Congress to provide $52 billion in government subsidies to boost U.S. semiconductor manufacturing. GM said that legislation could help "alleviate the ongoing shortage that continues to impact U.S. automotive manufacturing." (Reporting by David Shepardson; editing by Jonathan Oatis) Related video:
