Is Buick's surprise Detroit concept a Camaro-sized coupe?

Tomorrow night marks the unofficial start of the 2016 Detroit Auto Show. Keep your eyes peeled for a number of reveals, including a surprise debut from Buick. Yes, Buick. And we think it's going to be something really hot. According to a report from Bloomberg, the Tri-Shield's secret car could be a Camaro-sized sport coupe concept. As Bloomberg explains, it'd certainly gel with the impression the company is trying to put out – that it's no longer a brand for those with one foot in the grave. Introducing a sports coupe, even as a concept, could certainly reinforce that message. And if it happens to make production – which is not a certainty, Bloomberg's secret source says – it could certainly help Buick drive its average buyer age down from 59. Bloomberg doesn't offer any speculation on Buick's new coupe, but we have no problem making educated guesses. Our most reliable conjecture is this: it will ride on General Motors' Alpha platform, which underpins both the Camaro and the Cadillac ATS. And with a certain twin-turbocharged V6 in the GM stable, we've got an idea of what kind of engine could be shown. That speculation will have to suffice for now. But don't worry, we'll have official details, live images, and video tomorrow when Buick unveils its new concept in Detroit's Eastern Market.

Goodbye Chevy Bolt, hello baby Ram and electric Chrysler 300 replacement? | Autoblog Podcast # 779

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor Jeremy Korzeniewski. They kick things off this week with some news. The Chevy Bolt and Bolt EUV will be discontinued. The McLaren 750S gets revealed and a four-door new flagship McLaren are rumored. Did Chrysler show dealers an electric 300 replacement, did we spy a new compact Ram, and are we closer to a production version of the Genesis X Convertible? Also, Greg recently visited Michigan Central Station, which Ford is revitalizing. In this week's fleet, your hosts discuss driving the Genesis Electrified GV70, Chevy Tahoe RST Performance Edition and the Polaris RZR XP.

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.
