GM cancels CES date, possible Cadillac EV crossover unveiling

General Motors is bailing on CES 2020, the big annual consumer technology showcase in Las Vegas, after its plans to showcase an autonomous, electric vehicle were derailed by the 40-day UAW strike this fall. New evidence suggests that vehicle may have been Cadillac’s upcoming EV crossover. MotorTrend got GM to confirm that it was pulling out of CES, which takes place in January, though CEO Mary Barra in an interview said only that the vehicle they had planned to unveil was electric and featured autonomous technology — two key areas where the automaker plans to focus in the future. The automaker said the model simply wasnÂ’t ready. But MT said it then received an invitation from Cruise, GMÂ’s self-driving vehicle subsidiary, to an event later in January in San Francisco. That suggests the automaker could have been planning a different vehicle to show at CES than its self-driving Cruise AV “robotaxi,” which famously features no steering wheel or pedals. Cadillac showed off a digital rendering of a forthcoming unnamed electric crossover in Detroit in January, saying only that it would be available in both two- and all-wheel drive and sold globally. GM has said Cadillac will be its lead brand as GM delves into EV technology. The speculation is that the crossover will also feature CadillacÂ’s Super Cruise semi-autonomous highway driving technology. Whatever the vehicle was, or is, Barra said itÂ’ll be ready for viewing in the first half of 2020. GM has been developing the Chevrolet Bolt-based Cruise AV, a fully autonomous car, alongside its Cruise self-driving technology subsidiary, and building them at Orion Assembly plant near Detroit. It had once planned to debut a fleet of ride-hailing Cruise AV robot axis by the end of this year but realized the timeline was not realistic. Testing of the robot axis continues in San Francisco, Phoenix and Michigan. As for timing on a new timeline for fleets of Cruise AVs to take over the streets, Barra wouldnÂ’t show her hand. “We see a line of sight but weÂ’re not going to put another date out there,” she told MT, adding it was more important to “gain customer trust and usage.” As for Cadillac, any new reveal would likely come after the all-new Escalade SUV in February and amid a product blitz that will see it introduce a new or redesigned model roughly every six months through 2021.

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.

Safety group pans GM’s new Marketplace in-dash shopping

When it comes to our cars, is the Internet of Things a godsend? Or a hidden menace that will create more problems than it will solve? On the same day General Motors announced it will equip newer-model cars with its in-dash Marketplace e-commerce app, a prominent safety group was shooting it down. National Safety Council President Deborah Hersman tells Bloomberg the technology will only contribute to distracted driving and hurt efforts to stem the tide of rising auto fatalities, which grew 5.6 percent to more than 37,000 in the U.S. in 2016. The National Highway Traffic Safety Administration says distracted driving was responsible for 3,477 fatalities and 391,000 injuries in 2015, the most recent year for which it has data. "There's nothing about this that's safe," Hersman told Bloomberg. "If this is why they want WiFi in the car, we're going to see fatality numbers go up even higher than they are now." Marketplace, developed with IBM, will allow drivers — or more often, one hopes, their passengers — to order coffee or food, find gas stations and reserve hotel rooms from their dashboard screens. The technology is set to be uploaded automatically to nearly 1.9 million GM vehicles model-year 2017 and later that are equipped with WiFi hotspots and compatible systems. By the end of 2018, about 4 million Chevrolet, Buick, GMC and Cadillac vehicles will be equipped with Marketplace. The app will debut with a limited number of participating retailers, including TGI Fridays, Shell, Exxon Mobil and Starbucks, with more likely to join later. Online retail giant Amazon is also partnering with automakers such as Ford to bring e-commerce capabilities inside the car through its Alexa personal assistant. While convenience is nice, one other thing is becoming clear as the IoT wedges its way into our cars: It's taking aim at some decidedly first-world problems.Related Video: Image Credit: GM Buick Cadillac Chevrolet GM GMC Technology Infotainment in-car entertainment marketplace e-commerce
