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.

Recharge Wrap-up: Cadillac CT6 Plug-In on sale in China, Oregon utilities spur EV adoption

The Cadillac CT6 Plug-In is now available in China. The luxury plug-in hybrid sedan uses a turbocharged 2.0-liter engine plus two electric motors, which give the car a 0-62 mph time of 5.4 seconds. Its liquid-cooled 18.4-kWh lithium-ion battery pack gives the car an all-electric range of 50 miles, with a total range of 581 miles. Cadillac offers a 200V charger with the CT6 Plug-In, which provides a full charge in less than five hours. Owners can check charging status remotely using OnStar or the MyCadillac app. The CT6 Plug-In is offered in two variants, priced at about $80,400 and $94,800. Read more from GM. Two Oregon utilities are launching a program to increase EV adoption. Portland General Electric (PGE) will build six charging locations, each with up to four dual-standard fast chargers. PGE will also build and operate charging sites for electric buses, freeing up money for Portland's TriMet transit agency to spend on the actual buses. Pacific Power will also build public EV chargers, and lower some electricity rates for operators. Both companies will also work to inform the public about the benefits of electric mobility. Oregon utilities are required to stop using coal by 2030, and use 50 percent renewable energy by 2040, which will make EVs even cleaner. Read more at Green Car Reports. Continental says a shift to EVs will cost its company jobs. The automotive parts supplier's CEO, Elmar Degenhart, says that while the company will need to cut production jobs, those will be offset at least in part by the creation of new positions related to electric mobility. "There is enough time to design the process such that the blow is softened and major pain can be avoided," says Degenhart. Some 30,000 jobs at Continental are tied to combustion engines.

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.
