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.

2021 GMC Yukon Denali adds another extra-luxe accessories bundle

For the 2018 GMC Yukon Denali, GMC added a Denali Ultimate Package that combined every option already available with some 22-inch Midnight Silver rims. In 2020, GMC expanded build options for the Terrain with a Denali Premium Package, lumping together a couple of a la carte packages as an exclusive mix of features. The 2020 Yukon Denali configurator includes a lightweight Denali Premium Package, too, but for 2021 GM Authority reports the top-tier choices will expand to include an entry-level Denali Deluxe Package along with the Denali Premium and Ultimate options. The Deluxe Package checks the boxes for the Advanced Technology Package, Advanced Security Package, and the Rear Seat Media System. The long list of tech roped in with that trio includes adaptive cruise control, enhanced automatic emergency braking, rear camera mirror and washer, interior movement sensors, glass break sensors, dual 12.6-inch rear seat-mounted screens, two HDMI ports, and wireless projection capability. The exterior showpiece is a quartet of 22-inch bright machined aluminum wheels with premium paint, affixed with wheel locks. Go with those rims and the Denali Deluxe Package costs $5,750, opting for a different set of wheels can drop the price to $3,775. On top of that, choosing the right combination of options to go with the Deluxe Package can lower the price another $500. The Denali Premium Package includes almost everything above, only omitting the Rear Seat Media Package. In place of the screens for back-seaters, the bundle installs a powered panoramic sunroof and power-retractable assist steps with perimeter lighting. Purchased with the 22-inch wheels, this assortment runs $7,000, or $5,025 with a different set of wheels. Here again, the right combination of additional packages can save $500. The Denali Ultimate Package combines everything in the bundles above, plus the Max Trailering Package that gets GMC's ProGrade Trailering System and high-capacity engine cooling. The price is $10,460 on a rear-wheel drive Yukon Denali, $11,255 on the four-wheel drive models. Choosing a different wheel only saves $1,000 in this case, and there's no extra discount available. The 2021 Yukon is expected to enter production next month at GM's Arlington Plant in Texas, Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.

Engine block heater issues force GM to recall 324,226 diesel heavy duty trucks

General Motors has issued a recall on 324,226 diesel heavy duty trucks that could be susceptible to short circuits, and consequently, potential fire. The recall affects several models of heavy duty Chevrolet Silverados and GMC Sierras with optional engine block heaters. GM is recalling seven different truck models spread across three years. The recall affects the 2017-2019 Chevrolet Silverado 2500HD, 2017-2019 Silverado 3500HD, 2019 Silverado 4500HD, 2019 Silverado 5500HD, and 2019 Silverado 6500HD, plus the 2017-2019 GMC Sierra 2500HD and 2017-2019 Sierra 3500HD. Specifically, it includes these models with the 6.6-liter Duramax diesel engines and the optional engine block heater. The recall technically deals not with the engine block heater itself, but the way it is connected. According to NHTSA campaign No. 19V328000, the engine block heater cord or the terminals that link the cord to the heater could short circuit. A short circuit could potentially damage engine components and result in a fire. According to The Detroit News, 19 fires have been reported but nobody has been injured. GM has yet to figure out a fix, and thus has not yet released a notification schedule for affected customers. If you believe your vehicle is part of the recall, contact GM customer service at 1-586-596-1733 and use reference number N182206310.
