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.

Electric Cadillac Lyriq, Chevy Bolt EUV and more GM electric cars are on the way

GM’s murky and somewhat secretive electric car plan is falling into place, as the company dumped a massive amount of information about whatÂ’s in the pipeline at an event at its Warren, Michigan campus today. New EVs are going to be popping up across the GM brand lineup, with new entries from Chevrolet, Cadillac, GMC and Buick in progress. We also learned some big news about GMÂ’s new Ultium battery tech today, but check out this story for all of those nitty-gritty details. The electric vehicle onslaught will begin with the Cadillac Lyriq, an electric SUV thatÂ’s already been teased out. Naming it the Lyriq is the news today. No explanation for the name was provided, so weÂ’ll have to wait for April to learn more. GM didnÂ’t specifically say if the Lyriq would be launched at the NY Auto Show, but that show (assuming coronavirus doesnÂ’t cancel it) will begin on April 8 this year. Next up in the order of events is the GMC Hummer electric truck that we know will be launching on May 20. This truck will use GMÂ’s modular Ultium battery technology. However, the wait to buy a GMC Hummer will be a long one, as the truck isnÂ’t going to dive into production until fall 2021 at GMÂ’s Detroit-Hamtramck plant. GM revealed that its new modular Ultium batteries can be configured anywhere from a 50 kWh pack to a 200 kWh pack depending on the application. Range is estimated to be about 400 miles on the upper end with the largest battery pack, and GM continues to boast about a 0-60 mph acceleration time of three seconds. Charging estimates for the Ultium battery-equipped Hummer EV were also provided. GM says its truck platform will have 800-volt battery packs and be capable of 350 kW fast-charging. Time estimates werenÂ’t given, but those numbers suggest the truck will be a rapid charger. The Hummer truck on hand, which was the same that previously starred in GMC's Super Bowl spot, showed off removable roof panels that store in the frunk, as well as what appeared to be a version of GMC's Multi-Pro tailgate. It also featured sail panels on the sides, similar to those in front of the bed of the Chevy Avalanche. In addition to the Hummer, expect to see a couple Chevys launching. GM says the refreshed Bolt EV will be launched “in late 2020” with a refreshed interior and what appear to be thicker front seats.

10 electric cars we’re excited are coming soon

If you were considering buying an electric vehicle a couple years ago, we wouldn't fault you for thinking your options were limited, both in terms of quantity and quality. You just might not have been able to find an electric car that would suit your needs, lifestyle or budget. With the newest generation of EVs that have launched in the past year or two, your options have changed — and improved — dramatically. If you still don't see an EV you like, just wait a little while longer. It won't take long. There are a whole lot more on the horizon, and the problem may soon be in narrowing down your options. To give you an example, here are 10 electric vehicles we're excited about that you'll be able to buy very soon, from GM, from Germany, from Japan and more. Some of these will be available by the end of the year, and all are expected to launch by the end of 2023. The Chevy trio: 2024 Blazer EV, Equinox EV and Silverado EV GM is stepping into the future with strong footing. Following high-end electric launches from GMC (Hummer EV) and Cadillac (Lyriq), Chevrolet is bringing three electric vehicles with familiar nameplates. The 2024 Chevy Blazer EV (above left) will offer a number of versions, starting with the 2LT and RS trims in the summer of 2023, followed by the 557-horsepower SS in the fall and the base 1LT in early 2024. The 2024 Chevy Equinox EV (above right) will go on sale in fall 2023 as a limited-edition model, with volume sales ramping up in 2024, with a base cost of “around $30,000.” For those who prefer a bed to a liftgate, the 2024 Chevy Silverado EV is an electric pickup that looks more like the old Chevy Avalanche than the current Silverado. The WT (work truck) trim launches in fall 2023, while the 664-horsepower RST will follow in 2024.

It should go on sale before the end of 2022. The i7 xDrive60 will be the only variant, with its two motors providing a total of 536 horsepower and 549 pound-feet of torque, and its battery expected to offer a range of about 300 miles. Just like its internal combustion counterpart, this full-size sedan wonÂ’t come cheap, with the i7 starting at $120,295. 2023 Hyundai Ioniq 6 Following the Hyundai Ioniq 5, Kia EV6 and Genesis GV60, the 2023 Hyundai Ioniq 6 will be the fourth car using Hyundai GroupÂ’s E-GMP electric car architecture.
