Canada opens probe into 250,000 GM pickups, SUVs over brake performance

Transport Canada, the auto safety regulator, has opened a probe into braking issues in nearly 250,000 General Motors full-size pickups and SUVs after U.S. officials launched a similar probe last year, the agency said on its website. The U.S. National Highway Traffic Safety Administration (NHTSA) in November into 2.73 million U.S. 2014-2016 model year SUVs and pickups after receiving 487 reports of hard brake pedal effort accompanied by extended stopping distance that were attributed to deterioration of the engine-driven brake assist vacuum pump. Transport Canada's probe covers 249,700 2015 through 2017 model year vehicles including the Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon as well as 2014-2017 Chevrolet Silverado LD and GMC Sierra LD vehicles. The U.S. agency said it had reports of nine incidents of vehicles incurring damage as a result of colliding with another vehicle or fixed object at low speeds and reports of two injuries. NHTSA said if the pump fails to operate, the amount of brake power assist can be significantly reduced, extending vehicle stopping distance. The NHTSA sent GM an information request in a Feb. 7 letter. A GM spokesman said he had no update on the investigation. Reporting by David Shepardson; editing by Jonathan Oatis

GMC Hummer EV revealed as a 1,000-hp, 350-mile, fast-charging beast

The 2022 GMC Hummer EV has finally been revealed, and it certainly looks the part. It has chunky, squared-off styling, big tires pushed to the edges, and a towering fascia. But it’s not a case of form over function. On the contrary, the Hummer EV is has some pretty wicked technology and gear under the skin. The first version of the Hummer EV that will be available is the tricked-out Edition 1. It features three electric motors, which allows for torque vectoring. These motors make 1,000 horsepower, though GMC still hasnÂ’t given real-world torque numbers. The motors are fed by a 24-module Ultium battery pack. The pack can provide an estimated 350 miles or more of range. Not only that, but it supports 800-volt fast charging up to 350 kW. ThatÂ’s comparable to PorscheÂ’s charging system, and GMC says it can add an extra 100 miles of range in just 10 minutes. Later, a two-motor Hummer EV and a three-motor version without torque vectoring. The Hummer EV rides on fully independent suspension with adaptive air shocks. They can provide continuous damping adjustments for comfort, and have a height adjustment range of 6 inches. When set in its max-height off-road mode, it has two additional inches of ground clearance, and the "Extract Mode" will lift it six inches higher than default. The Edition 1 model also comes with standard 35-inch mud terrain tires, and combined with the suspension, the Hummer EV has a fording depth of 2 feet and the capability to climb over an 18-inch vertical obstacle. Owners will be able to easily add more clearance since GMC made the wheel arches large enough to accommodate aftermarket 37-inch tires. Additional off-road goodies include skid plates along the chassis, rock sliders, the previously covered four-wheel steering with Crab Mode diagonal driving, and 18 camera views including angles under the truck for getting over rocks. Those cameras feature sprayers, too to keep them clean. Detailed information on torque output, torque vectoring, tire pressure, vehicle angles and more are also displayed on the infotainment screen. Speaking of that infotainment screen, itÂ’s a massive 13.4 inches and is paired with a 12.3-inch instrument display. They feature proudly in a squared-off, rugged-looking interior. The Hummer EV will get the latest version of Super Cruise, complete with automatic lane-changing. The Edition 1 gets the removable roof panels as standard, and those roof panels are clear, so you can still get some sun with them in place.

GM seeks national mandate for zero-emissions cars

DETROIT — General Motors says it will ask the federal government for one national gas mileage standard, including a requirement that a percentage of auto companies' sales be zero-emissions vehicles. Mark Reuss, GM's executive vice president of product development, said the company will propose that a certain percentage of nationwide sales be made up of vehicles that run on electricity or hydrogen fuel cells. GM says a nationwide program modeled on such a requirement in California could result in 7 million electric vehicles, or EVs, on U.S. roads by 2030. California wants 15.4 percent of vehicle sales by 2025 to be EVs or other zero emission vehicles. Nine other states, including Maryland, Massachusetts, New Jersey and New York, have adopted those requirements. In January, California Governor Jerry Brown set a target of 5 million zero-emission vehicles in California by 2030. The Trump administration criticizes California's ZEV mandate, saying it requires automakers to spend tens of billions of dollars developing vehicles that most consumers do not want, only to sell them at a loss. Reuss told reporters that governments and industries in Asia and Europe "are working together to enact policies now to hasten the shift to an all-electric future. It's very simple: America has the opportunity to lead in the technologies of the future." A national mandate also would create jobs and reduce fuel consumption, CO2 emissions and "make EVs more affordable," Reuss added. GM, the nation's largest automaker, will spell out the request Friday in written comments on a Trump administration proposal to roll back Obama-era fuel economy and emissions standards, freezing them at 2020 levels instead of gradually making them tougher. Under a regulation finalized by the Environmental Protection Agency at the end of the Obama administration, the fleet of new automobiles would have to get 36 miles per gallon by 2025, 10 mpg higher than the current requirement. But the Trump administration's preferred plan is to freeze the standards starting in 2021. Administration officials say waiving the tougher fuel efficiency requirements would make vehicles more affordable, which would get safer cars into consumer hands more quickly. GM on Thursday said it doesn't support the freeze, but wants flexibility to deal with consumers' shift from cars to less-efficient SUVs and trucks.
