Opel CEO talks new EV, will likely be fresh face for Chevy, too

The rumored demise of the Opel Ampera has been confirmed, but there's good news, too. Opel CEO Karl-Thomas Neumann has been busy Tweeting information about the brand's next plug-in vehicle, admitting that the Ampera is on the way out but that plug-in vehicles are here to stay. His Tweets, in full, read: After the eventual run-out of the current generation Ampera, we'll introduce a successor product in the electric vehicle segment. Our next electric vehicle will be part of our massive product offensive – with 27 new vehicles in the 2014-2018 time frame. We see eMobility as important part of the mobility of tomorrow and we will continue to drive down costs & deliver affordability. As we learned earlier this week, the Ampera will not be refreshed when the current Chevy Volt is updated, most likely because of slow sales. Opel sold just 332 Amperas in the first five months of 2014. For now, General Motors is still building Amperas in Michigan for export to Europe. So, what might this new EV mean for the General Motors plug-in fleet? Official spokespeople are being quiet, but we think it's safe to say the new EV Neumann is talking about is not simply a rebadged Chevy Spark EV. This is the first official word about an entirely new EV, and we expect it will come to both the Chevrolet and Opel brands.

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.
