Watch the live reveal of the 2014 Chevy Silverado and GMC Sierra [UPDATE]

UPDATE: The trucks have been revealed. Click here for all of the official details.
As promised, Chevrolet and GMC are offering a live webcast of the world premiere for the all-new 2014 Silverado 1500 and Sierra 1500. After being teased with spy shots and blurry images like the one above for ages, now is the time to see the trucks in the metal, for real (well, as 'real' as it gets on a webcast, at any rate).
Shift your eyes down just below to see the reveal as it happens, starting at 9:30 AM EST. We anticipate having loads of images full technical information to share after the webcast, too, so truck aficionados should stay tuned. We'll also be bringing you live images of both trucks too, when we see them on the show floor at next month's Detroit Auto Show.

GM can't keep up with most popular pickup orders

With the market for pickup trucks at its best since before the recession, General Motors can't afford any hiccups with the launch of its new 2014 Chevrolet Silverado and GMC Sierra twins, but it sounds like the popularity of V8-powered trucks is causing some supply-chain issues. Bloomberg reports that GM is experiencing a shortage of 5.3-liter V8 engines because an unnamed parts supplier has been unable to keep up with demand. This is leading GM to restrict the number of V8 Silverado and Sierra trucks that Chevrolet and GMC dealers are allowed to order.
Although it's unclear how long it will take to resolve the parts shortage, GM doesn't have much time to sort it out, as a new Ford F-150 looms on the horizon. At launch, GM's fullsize trucks were offered only with a base 4.3-liter V6 and the 5.3-liter V8, but a burlier 6.2-liter V8 will be available soon. Interestingly, at least at the moment, GM truck buyers don't seem as willing to downsize to V6 power as buyers of the F-150, which gets some 42-percent of its sales from trucks equipped with its EcoBoost V6 engine (not including the normally aspirated base V6).
Working out the kinks in the Silverado and Sierra's supply chain couldn't be more important to the health of the company. Full-size pickups are a huge profit driver - in 2012, the trucks were said to make up about two-third of GM's total profits.

2020 Chevrolet Tahoe, Suburban and GMC Yukon all spied with production lights

One of our spy photographers just caught a smattering of full-size GM SUVs out testing, including the Chevrolet Tahoe, Suburban and GMC Yukon. Previous spy photos of the next-generation of these big GM SUVs have revealed that GM is going with an independent rear suspension design, and these shots confirm the news once again with our best look at the hardware yet. Check them out from the rear, lined up like ducks in a row to see the beefy control arms down there. This will undoubtedly give the big SUVs a more compliant ride, and should bring it back into touch with the refinement from the Ford Expedition and Lincoln Navigator. The new bits we get to see with these shots are production headlights and taillights that are shaping up to look pretty neat. Most distinguishable are the GMC Yukon's LED DRLs. These look a lot like the C-shaped LEDs outlining the headlights on the Sierra, but they have an extra LED strip on top of the C. The parts of the taillights that we can see look significantly different than that found on the Sierra, showing GM is planning on having a great deal of differentiation there. We can sort of see through the mesh covering the grille to what appears to be a classic horizontal bar style front opening. Chevy is predictably dialing the crazy LED strip design back for the Tahoe and Suburban. The parts that are lit up look a whole lot like the headlight fixtures on the 2019 Silverado. That truck uses a stack of lights with the actual headlights separated from the DRLs. We can see the same thing going on here, with the headlight up top and curved LED DRL strip sitting below. It's tough to say if the designs are exactly alike, but we expect to see an extremely Silverado-esque look once all the camouflage comes off. Chevrolet's taillight design differs from its donor truck like the GMC, showing off a curved, vertical series of LEDs out back. Once production lights start popping up like this, we know the vehicle is moving closer to its end game. A reveal sometime later this year could be in the cards for GM's next batch of full-size SUVs. It certainly needs them quick, as Ford rockets ahead with increased Expedition production announced earlier this week.
