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.

GMC Terrain headlight recall fix is a sticker

This GMC Terrain recall over a headlight issue has gone from fascinating to absurd. It started when GMC discovered the headlights on the 2010-2017 Terrain were out of compliance with Federal Motor Vehicle Safety Standards (FMVSS). A pinpoint of low-beam light was being reflected off the high-beam reflector. This bounced a tiny sliver of bright light up into the trees and the sky beside the road, not into oncoming traffic. GMC did the right thing, reporting the noncompliance to the National Highway Traffic Safety Administration. Because the sliver of light was coming from the low beams and was four times brighter than the maximum allowable low beam brightness, the NHTSA told GMC to recall 740,581 units of the SUV. GMC asked for an exemption, admitting the bright spot could cause glare while noting the errant beam didn't affect other road users. The automaker hadn't received any complaints, only a comment from one owner saying the lights put a bright spot in the trees on the other side of the road. The NHTSA denied the request. GMC began notifying owners in April that they'd need to come in for a fix once a fix had been developed. That's the fascinating part. The absurd part, which Tire Meets Road uncovered, is that the fix is a "Headlamp Applique Kit." Which is a piece of frosted tape applied to the outside of the headlight that lets low-beam light through and tamps down any potential glare from the caroming beam. Notice that the parallelogram of frosted tape matches the L-shaped frosted area along the inside of the headlight housing. That portion was already a feature of the lamp, as can be seen in our 2016 Terrain Denali Quick Spin. The repair needs a trip to the dealer for a tech to place a positioning template over the headlight and put the applique kit in the proper spot. GM's instruction kit says the whole thing should take 0.2 of an hour, or 12 minutes—about the time it it would take to get checked into and out of the dealership service department. Owners aren't impressed, some calling the fix unnecessary and ridiculous, and the tape should make it clear that GMC feels the same way. Some owners have said they're going to skip the recall. Those drivers will find that just as GMC couldn't escape the legal ramifications, neither can they. Local motor vehicle bureaus keep track of recall compliance.

GMC Hummer EVs 'sold out for two years or more'

At the end of March this year, GMC said it had 65,000 reservations for the Hummer EV pickup and SUV. At the time, brand chief Duncan Aldred said, "Production’s actually slightly ahead of plan and weÂ’re putting things in place now to actually expedite that as well, so we can deliver these reservations quicker than we originally thought. WeÂ’re seeing momentum building," adding that "it still means a reservation now probably means delivering in '24." By the time of the 2024 GMC Sierra EV Denali Edition 1 reveal just a bit ago, that reservation number had climbed to 90,000. GMC shut down the Hummer reservations line a month ago. GM Authority reports that when GMC chief Duncan Aldred spoke at a media briefing ahead of the Sierra EV reveal, he said the Hummer is "sold out for two years or more."   Notice, the word "probably" has been replaced by the phrase "or more" in the production vocabulary. That development likely takes into account what's happened since March at GM's Factory Zero, where the automaker currently builds the Hummer. That site, along with the new Orion Township Assembly Plant, will soon build the Chevrolet Silverado EV, GMC Sierra EV and Cruise Origin autonomous vehicle. In a memo from the beginning of the year, GM said a $6.6 billion investment in EV production capability will ultimately allow 600,000 electric pickups to come off lines every year. That's at least a couple of years away, though. At the beginning of October, GM said it wanted to bump production of the EVs on sale now, which includes the Chevrolet Bolt, to 70,000 vehicles in 2023. Back to the Hummer, GMC increased September Hummer production to 700 units for the month. That was a huge bump over the monthly average in the nine months up to September, the production totaling 2,750 units for the first three quarters, yet well behind what the brand would like. And Factory Zero will shut down for a few weeks in November for upgrades to produce the additional vehicles. All of this assumes the supplies of chips and raw minerals for batteries, industrial supplies and industrial transport don't suffer another hiccup. If there's any good news buried in all this, it's that 95% of Hummer reservation holders were converting to paid orders, an absurdly positive number. Based on what we've seen so far, GM's got some good looking EVs on the way. Let's cross our fingers that the company can build them quicker. Related video: This content is hosted by a third party.
