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 patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Junkyard Gem: 1980 Chevrolet LUV Mikado

During the 1970s and into the 1980s, each member of the Detroit Big Three imported Japanese small pickups and sold them with Ford (Mazda Proceed), Dodge/Plymouth (Mitsubishi Forte), or Chevrolet (Isuzu Faster) badges here. Ford developed the Ranger and killed the Courier for 1983 (though Americans could still buy the Mazda-badged version all the way through 1993), while The General axed the LUV after the S-10 debuted in the 1982 model year. Isuzu sold the same truck as the P'up through 1987, though, and we might as well follow up our recent P'up Junkyard Gem with its LUV predecessor. LUV stood for Light Utility Vehicle, and I've managed to spot a handful in the boneyards over the years. This one now resides in a yard in northeastern Colorado. The Mikado trim package included striped seat upholstery and a sporty steering wheel, plus these cool dash badges. As far as I can tell, no LUV Mikado advertising featured any Gilbert and Sullivan tunes. This one is fairly rusty for Front Range Colorado, and it has endured a bed swap from some other small truck. The engine is the 75-horse Isuzu 1.8-liter. Members of this engine family went into everything from Chevy Chevettes to Isuzu Troopers in the United States. Very unusually for a small pickup during the Malaise Era, this one has a luxurious automatic transmission. Acceleration must have been a leisurely affair in this truck. Air conditioning? Unheard of! Someone stuck every one of their lunchtime apple stickers on the driver's door. After 41 years of work, this truck is done. Come on strong in a LUV of your own!
