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.

Some 2012-13 Chevy Volts may not have enough battery coolant

The 2012 and 2013 model year Chevrolet Volt extended-range plug-in vehicle may have a battery glitch caused by low coolant levels. No recall has been issued and General Motors is taking care of the issue at no cost to drivers. Some of the affected Volts may have lower-than-advisable coolant levels because of some pesky air pockets in the car's cooling circuit. When the coolant levels get too low, the charging system for the battery powering the car's onboard generator (i.e. the Rechargeable Energy Storage System, or the RESS) may be shut down, turning one's Volt into a run-of-the-mill gas-powered car, and a pricey one at that. The Car Connection says GM is advising owners of the '12 and '13 Volts to contact their local Chevy dealer for a free fix. GM representatives didn't immediately respond to a request for comment from AutoblogGreen for more details. We believe this is a separate issue than the one that brought 8,000 Volts back to the dealers for a battery coolant fix, what GM called a "voluntary customer satisfaction effort," a few years ago. General Motors sold 23,094 Chevy Volts last year after selling 23,461 Volts in 2012, so that fix-it list may get fairly lengthy. Check out a GM-Volt.com user thread related to this issue here. *UPDATE: Chevrolet spokesman Randy Fox confirmed in an e-mail to AutoblogGreen that the company issued a service bulletin to dealers that they may need to top off coolant levels on certain Volts because of the issue, and that the vehicle will "return to normal charging operation" once that's done.

GM's European Opel division may eventually go all-electric

General Motors' Opel division in Europe may transform itself into an all-electric vehicle maker by 2030. Granted, a lot can happen between now and then, including a potential buyout by French automaker PSA Group. Regardless, Opel appears to view its electric future beyond the Ampera-e, which is the sister vehicle to the Chevrolet Bolt, and more like Tesla. Opel CEO Karl-Thomas Neumann indicated that focusing on electric drivetrains would be a superior strategy to expanding its EV technology while pushing forward with conventional drivetrains, says Automotive News Europe, citing comments Neumann made to German publication Manager Magazin. General Motors could make the decision to move towards an all-electric vehicle line for Opel as soon as May. Of course, that depends on whether Opel is bought out by PSA, the parent country to Peugeot and Citroen. PSA is in talks to buy General Motors' Opel and Vauxhall divisions, though government and labor representatives in Germany have expressed concerns over potential job losses from the proposed buyout, Reuters says. Regardless, GM has hinted at expanding its electric-vehicle line far beyond the Bolt, which has a 238-mile single-charge range and debuted late last year. Mary Barra, in an interview with CNET, said the Bolt's all-electric platform could be applied to a "huge range of vehicles," though wasn't specific about additional EV models. Opel first showed off its Ampera-e at the Paris Motor Show last fall. The name of the model raised some eyebrows because the Ampera badge had been previously used by Opel for the sister version of the Chevrolet Volt extended-range plug-in. Either way, Opel is looking to take on Renault for electric-vehicle sales supremacy across the Pond. Related Video:
