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.

Is this GM's next electric crossover?

GM made headlines this week when CEO Mary Barra presented the company's electrification and automation plans at the Barclays Global Automotive Conference in New York. "We are committed to a future electric vehicle portfolio that will be profitable," Barra said, which could be taken as a jab at Tesla. In the presentation ( PDF here), though, we see a new vehicle in a slide titled "Leveraging existing BEV platform to expand in near term." The vehicle, seen above, accompanied the captions "New CUV entries" and "two entries by 2020." Is this a sneak preview of an upcoming electric crossover from GM? The image seems too realistic and intentional to be a random placeholder. If this is, indeed, an upcoming battery-electric CUV based on the Bolt, the question remains: Will it be a Chevy or a Buick? It has no visible badging, but it shares DNA from both brands. As Inside EVs points out, though, it does bear a resemblance to the Chevrolet FNR-X concept unveiled in Shanghai earlier this year. With two CUVs on the way, it's not unthinkable that there could be a version for each brand. In addition to this slide, the presentation includes plans for an "All new multi-brand, multi-segment platform" launching in 2021. The all-new modular battery system will cost less than $100 per kWh, providing higher energy density and faster charging. The platform will host at least nine different vehicles, including a compact crossover, seven-seat luxury SUV and a large commercial van. GM has said it will launch 20 new EVs by 2023, and that it targets 1 million EV sales per year by 2026. Many of those sales will be in China. Related Video:

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.
