GM to make most cars LTE hotspots for 2015

General Motors isn't the first automaker to deliver in-car Internet access, but a proposed plan announced today could make the technology more widespread than any of its competitors have offered. By the 2015 model year, most Chevrolet, Buick, Cadillac and GMC products in the US and Canada will offer 4G LTE mobile broadband access. Initially, GM will just be pairing with AT&T to deliver this service, but additional carriers will be revealed in the future.
Current in-car Wi-Fi hot spots are limited to 3G, but GM says that 4G LTE is 10 times faster than 3G service and will allow for full Internet access, including streaming video for entertainment as well as services like real-time traffic updates and navigation driving directions. There is also no need for a paired smartphone with this new system, which should make it easier to use, and GM and AT&T will also be working together to develop new apps for customers.
Buyers can expect to start seeing 4G LTE in their cars starting next year, and GM is already planning to expand the service to other global markets as well. All of the information from GM's announcement is posted in a press release below.

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.

Chevy brings back Midnight Edition Colorado and Silverado for 2016

Chevrolet is capitalizing on the popularity of last year's shadowy Midnight Edition pickups with new versions at the Chicago Auto Show. The package's darker trim allows buyers to make their trucks look a little more menacing straight from the dealer. The 2016 Midnight Editions don't deviate from last year's monochromatic theme. The trucks feature blacked-out trim from the grille, badges, bumpers, and headlight bezels. The obsidian shades also appear on the side moldings and painted wheels. Chevy completes the dark theme with a black spray-in bedliner. Available with the Z71 package, customers can also get off-road equipment like an upgraded suspension, locking rear differential, and hill descent control – depending on the model. Chevy offered the Midnight Edition for the Silverado and Colorado last year, in addition to other models, and customers couldn't get enough of the dark trucks. "The Silverado 1500 Midnight was by far the most popular model in 2015, as demand outstripped supply in a matter of months. It only made sense to expand our special-edition offerings for 2016, including new Midnight editions," Sandor Piszar, Chevy's truck marketing director, said in the models' announcement. Chevy spokesperson Monte Doran told Autoblog the 2016 Midnight Edition pickups will be available this spring, but he wouldn't comment on pricing. You can get a good look at what to expect in the gallery above and expect live photos soon.

They join a growing portfolio of special-edition trucks whose popularity helped Chevrolet truck sales increase 27 percent last year – double the increase for the total truck market. "We introduced several special-edition trucks in 2015 – each combining equipment and appearance packages designed for specific enthusiasts in mind," said Sandor Piszar, Chevrolet truck marketing director. "They clearly resonated with buyers, as the special editions sold in one-third the time, and to younger, more affluent buyers than the industry average. "The Silverado 1500 Midnight was by far the most popular model in 2015," Piszar continued, "as demand outstripped supply in a matter of months.
