GMC Hummer EV heads north for winter

GMC announced early Tuesday that its new Hummer EV pickup is ready to head north for winter testing. What might seem like a trip in the wrong direction to us warm-blooded enthusiasts is a critical next step in the development of GM's new electric truck.  We also got a couple of teaser pics of the Hummer EV at GM's Milford Proving Grounds, along with two shots of development prototypes being assembled, of which GM says it has "a series." There's not much new to see here, but GM says there's more to come. "The GMC HUMMER EV has arrived at GM’s Milford Proving Grounds to continue validation tests and will head to northern Michigan to run through the teamÂ’s grueling winter testing process," GM said in its announcement. "We will document the journey and share updates in the coming weeks and months." The GMC HUMMER EV arrived at GM?s Milford Proving Grounds to c View 3 Photos The GMC Hummer EV Edition 1 will feature three electric motors, enabling torque vectoring. GMC says these motors produce 1,000 horsepower, though we don't yet have a final torque figure. Power comes from a 24-module Ultium battery pack which can provide an estimated 350 miles (or more) of range. GMC says this new architecture supports 800-volt fast charging up to 350 kW, which is comparable to the system Porsche introduced with its Taycan electric sedan, and GMC says it can replenish 100 miles of range in just 10 minutes. Planned variants include a two-motor setup, and an alternative 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 two feet and the capability to climb over an 18-inch vertical obstacle. Edition 1 Production begins late next year, with a starting price of $112,595. In fall 2022, we'll see the regular top trim starting at $99,995; In spring 2023, weÂ’ll get a mid-level trim that has three motors, air suspension and four-wheel steering -- but no torque vectoring -- starting at $89,995. 

GM recalls 3,300 pickups and SUVs for new ignition-switch issue [UPDATE]

UPDATE: A statement from GM about the recall has been added below. The exact total of vehicles affected is 3,296, including 3,073 of them in the US. General Motors isn't letting an ignition-switch problem grow into a massive scandal again. The automaker is recalling about 3,300 North American trucks and SUVs. They are: the 2014 Chevrolet Silverado and GMC Sierra and the 2015 Chevy Suburban and Chevy Tahoe, as well as 2015 model heavy-duty pickups, the Detroit News reports, citing an Associated Press story. The issue appears to have been caught fairly quickly. In this case, the keys can get stuck in the "start" position and then slip to "accessory" if bumped. This is because the ignition lock gears have an outer diameter that's larger than the specifications allow. When that happens the engine shuts off, and the driver loses assistance to the steering and brakes. The airbags might also be affected. The vehicles get a new ignition-lock housing to fix the problem. According to the Detroit News, an employee who experienced the problem with the switch discovered the issue, and this person then let officials at the automaker know as part of the Speak Up for Safety program. A total of five reports of the fault were discovered. However, there are no cases of injuries or crashes. The claims to the automaker's resolution program eventually tallied that GM's previous ignition switch problem included 124 deaths and 275 injuries. The company also had to recall millions of vehicles and pay significant fines to the US government. GM Statement General Motors is recalling 3,073 full-size trucks from the 2014 and 2015 model years in the U.S. Some of these vehicles may have an ignition lock actuator gear with an outer diameter that exceeds specifications, which may make turning the ignition key difficult. The ignition key could get stuck in the "start" position. This may be more likely at higher interior ambient temperatures. If the vehicle is driven with the key stuck in the "start" position, and the vehicle experiences a significant jarring event or the vehicle's interior temperature cools, the ignition lock cylinder could move out of the "start" position, rotate past the "run" position, and move into the "accessory" position, leading to loss of power steering assist, power brakes and potentially air bag deployment in certain crashes. Dealers will replace the ignition lock housing.

2021 Chevy Silverado, GMC Sierra fuel economy to go down due to global chip shortage

Production of the 2021 Chevy Silverado and 2021 GMC Sierra is continuing, but the global semiconductor chip shortage is resulting in a mid-year change. Or rather, an omission.  Basically, the availability of cylinder deactivation for the 5.3-liter V8 will be significantly reduced, resulting in a reduction of 1 mpg combined for affected models. This applies whether that engine has the six- or eight-speed automatic, as well as to both the regular Active Fuel Management and the more advanced Dynamic Fuel Management cylinder deactivation systems. DFM does remain with the pairing of 5.3-liter V8 and 10-speed automatic that comes standard on the LT Trail Boss and High Country. "Due to the micro controller shortage, the components that control AFM/DFM in the engine control module (ECM) have been removed," GM spokesperson Michelle Malcho told Autoblog. She also indicated that the engines will still have the AFM/DFM hardware in place, but that GM will not allow activation of the systems in the future with an ECM change.  Malcho also confirmed to Autoblog that the Silverado and Sierra's other engines will continue to have AFM and DFM, including the 2.7-liter turbo inline-four, 4.3-liter V6 and 6.2-liter V8. In an earlier statement to Reuters, she declined to say the volume of vehicles affected. "By taking this measure, we are better able to meet the strong customer and dealer demand for our full-size trucks as the industry continues to rebound and strengthen," Malcho wrote Reuters in an email. The change runs through the 2021 model year, she said. Malcho told Reuters it would not have a major impact on the Detroit automaker's U.S. corporate average fuel economy (CAFE) numbers. "We routinely monitor our fleet for compliance in the U.S. and Canada, and we balance our portfolio in a way that enables us to manage unforeseeable circumstances like this without compromising our overall (greenhouse gas) and fuel economy compliance," she said. GM's fleetwide fuel economy in the 2018 model year was 22.5 miles per gallon and was projected to rise to 22.8 mpg for 2019, according to a report by the Environmental Protection Agency. To meet federal CAFE requirements, automakers like GM often use credits from either earlier years where they faced less stringent rules and performed better than the requirements or buy credits from other automakers. GM said last month the chip shortage could shave up to $2 billion from this year's earnings.
