Buick Velite is a not-so-Volt-like plug-in hybrid concept for China

Is the Buick Velite a Volt by any other name? That's a question worth asking after General Motors said that the Buick Velite concept vehicle will make its global debut at the Guangzhou Auto Show later this month. GM says the car "will provide a template for upcoming models being launched under the Buick Blue new energy vehicle strategy." Whether that means the Velite is a variant of the second-generation of the Chevrolet Volt extended-range plug-in is open to interpretation. Some automotive publications, including Autoweek, are saying that's the case, but GM China doesn't mention the Volt in its press release, only saying that the car is a "high-performance" plug-in hybrid vehicle. As we know, GM doesn't use the "PHEV" descriptor for the Volt, which makes us thing the Velite's powertrain is more like the Cadillac CT6 PHEV. Either way, the concept was developed by the Pan Asia Technical Automotive Center (PATAC), which is a joint venture between GM and Shanghai-based SAIC. As far as the name, GM has been shopping the Velite moniker around for a while now. The automaker first used Buick Velite for the convertible concept vehicle it showed off at the 2004 New York Auto Show. More recently, GM in 2014 filed to use the name for the US variant of its Opel Cascada four-seat convertible model, which debuted in 2013. As for the second-generation version of the Volt, that model appears to be gaining favor in the US. Domestic sales of the Volt through October have surged 64 percent from a year earlier to more than 18,500 units. The new version boosted its all-electric range by 40 percent to 53 miles while increasing its power output by 20 percent.

GM might share the Chevy Volt's powertrain tech with rivals

Car shoppers might eventually find the award-winning powertrain from the second-generation Chevrolet Volt under the hood of another automaker's vehicle – at least if General Motors global powertrain chief Dan Nicholson gets his way. According to Automotive News, Nicholson would be open to partnerships with other companies to share the range-extended setup. "We want to be the partner of choice in propulsion system development in this complex and turbulent era we are approaching," he told the trade publication. For an automaker that wants an electrified solution, the Volt's system would be an easy choice. It combines a 1.5-liter four-cylinder with two electric motors and an 18.4-kWh lithium-ion battery. The EPA estimates the setup is good for 106 MPGe combined and 53 miles of EV range in the Volt. Wards selected the powertrain for its 10 Best Engines list for 2016, and the Chevy won the Green Car of the Year Award. According to Automotive News, a partnership could have serious financial implications for GM and its collaborator. Rival automakers could get a competitive powertrain without the huge expense of research and development. Meanwhile, The General would benefit from larger economies of scale to drive down prices. Don't look for the Volt's powertrain to arrive in other vehicles too soon, though. GM spokesperson Kevin Kelley told Autoblog that he was "not aware of anything going on" in regards to negotiations with other automakers. In the meantime, we'll keep our eyes open for companies borrowing the Bowtie's advanced tech.

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.
