Thanks for keeping us on our toes, Detroit Auto Show [w/poll]

Here at Autoblog, we love unexpected debuts at auto shows – and judging by our Detroit Auto Show comments and traffic, you do, too. Surprise reveals have been fewer and farther between in recent years with so many ways for vehicles to be teased or leak out, but this week's show has been a revelation. More to the point, it's been a series of revelations, with automakers from around the globe successfully delivering a brace of concept and production surprises. It's made our jobs a lot more exciting and challenging this week, and even though it's actually more work to react and run-and-gun when the sheet is pulled on a surprise reveal than it is to publish an already-written embargoed story, we've had more fun covering this show for you than any domestic show in memory. We hope you've enjoyed the surprises along with us. To that end, borrowing the words of an unnamed automaker PR flack, we'd like to thank the following automakers for enduring "mountain of antacids" and that "creeping sense of paranoia" necessary to keeping ones' wares totally under wraps until the sheets are pulled off the sheetmetal: Buick Avenir concept Chevrolet Bolt concept Ford GT concept Ford Mustang Shelby GT350R Ford F-150 SVT Raptor Hyundai HCD-15 Santa Cruz concept And while we're at it, we'd like to throw in an shout-out to Detroit's substantially revised and revitalized Cobo Center, and in particular, the redone Michelin media center, which is arguably the single best accommodations for writing show stories that we've encountered on the entire international circuit. Well done, everyone. Thank you, and keep the surprises coming. Auto News Detroit Auto Show Buick Chevrolet Ford Hyundai Volvo 2015 Detroit Auto Show

GM sweetens military discount for Buick, Chevy and GMC

American servicemen and women interested in a new vehicle from Chevrolet, Buick or GMC now have a bit more incentive to head down to their local dealer, as General Motors has announced plans to improve its military discount program.
The new GM Military Discount Program offers eligible consumers a new Chevy, Buick or GMC at invoice pricing, which in some cases can take very large chunks out of a car's retail price. When factored in with other incentives, most of which are available with the Military Discount, the bargains are thick on the ground for members of the US armed forces.
GM's Retail Sales and Marketing Support general manager, Chuck Thomson, said, "GM has long supported the military and military families, and we hope this simplified and enhanced discount will show our appreciation for their service and help make it easier for them to own one of our great new vehicles." The program is open to all active duty and reserve members in the Army, Navy, Marines, Air Force, National Guard and Coast Guard, as well as veterans that have been out of the service for less than a year. Military retirees and their spouses are also eligible for the discount.

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.
