Buick Encore, Chevy Trax reportedly dead after 2022

The Buick Encore will not get an encore, and the Chevrolet Trax is dead in its tracks. Separate unverified reports say the two crossovers, which are essentially identical underneath the sheetmetal, will retire at the end of the 2022 model year without being directly replaced. Citing anonymous sources, enthusiast website GM Authority wrote that production of the Encore and the Trax is scheduled to end in the third quarter of 2022. Both models are manufactured in Bupyeong-gu, South Korea, and General Motors will reportedly use the extra production capacity to build more examples of the Trailblazer, which outsold the Encore and the Trax combined by a significant margin in 2021. General Motors hasn't commented on the report, but we wouldn't be surprised if the end is indeed near for the Encore and the Trax. Buick released the Encore for the 2013 model year, and Chevrolet launched the Trax for 2015, but the model made its debut as the Opel Mokka in 2012. It's at the end of its life cycle, and sales figures reflect this: 20,072 units of the Encore were sold in America in 2021, a drop of 52% compared to 2020, while 42,590 examples of the Trax found a home, a 60% decline. It's further proof that Americans don't like small cars. Viewed in that light, the decision not to replace either crossover makes perfect sense. If the report is accurate, the Encore GX (which is not related to the Encore in any way) will enter the 2023 model year as Buick's entry-level model. The situation is a little more complicated at Chevrolet: The pocket-sized Spark is on its way out in 2022 as well, meaning that the Trailblazer will become the entry point into the range. It's a different story in Europe: Opel, which is now part of the Stellantis group, released the second-generation Mokka in June 2020.

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.

Surprise! GM putting aluminum in next-gen pickups

Last month, General Motors launched a series of ads touting the benefits of steel over aluminum – specifically, with regard to the Chevy Silverado versus the Ford F-150. (Kind of. We're not sure what a grizzly bear has to do with anything.) We took issue with the ads, with editor in chief Mike Austin saying they "reek of insecurity, and distract from the Silverado's strengths that could be used for positive advertising." But what bothers us more, is that yet another report surfaced claiming anti-aluminum GM will indeed use the weight-saving material in its next-generation fullsize trucks. On Tuesday, GM announced a $877-million investment for its truck plant in Flint, MI. But Reuters says that huge overhaul is because the trucks will use "substantially different equipment than the tools GM uses today." The report specifically states, "People familiar with the company's plans say GM's next-generation pickups and SUVs will make use of various materials, including aluminum and lightweight steel, to shed weight and gain fuel efficiency to meet tougher federal standards." The Silverado already uses a few aluminum components in the engine and hood, and if more widespread use will help GM build its best fullsize trucks ever, then that's great. Honestly, we have no reason to doubt that aluminum will be used in the next Silverado and GMC Sierra. We just hope GM remembers that nothing is ever truly deleted from the bowels of the Internet when it launches the subsequent "look how great aluminum is!" campaign.
