GM crab walked the Hummer EV truck up and down Woodward this weekend

Sometimes, manufacturers like to show off their fancy new wares at the Woodward Dream Cruise. It’s largely done through static showcases with big displays for the public to gawk at. However, GM did something a little different with its GMC Hummer EV truck this year. Instead of parking it at the Chevy and GM display area, it took to Woodward Avenue itself to show off the Hummer in pre-production form. Not only did GM drive the electric truck on the road in front of thousands, but it crab walked the whole way. This was our first time, and probably most of the publicÂ’s first time seeing the Hummer EV crab mode in person. Judging from the crowdÂ’s reaction (GM got its wish of everybody paying attention), folks are impressed, and maybe a bit confused at the HummerÂ’s sideways movements.  ItÂ’s a strange spectacle to see in person. At first, the truck appears as though itÂ’s sliding sideways on ice in a smooth, graceful slide. ThatÂ’s because even though the wheels are turned, the front of the truck is still pointing dead straight ahead. The GM employee behind the wheel of the prototype appeared to be moving forward at about 5-10 mph — it appears shockingly quick in person for the way this behemoth of a truck presents itself. The tech making it work is rather simple in concept. GM simply took existing rear-wheel steering technology, then amplified and modified it for this type of movement. Whereas most cars with rear-wheel steering max out at around 5 degrees of lock with the rear wheels, this Hummer can turn the wheels up to 10 degrees. Turn the wheel left or right in crab mode, and the Hummer moves diagonally down the street. If you use it for its intended purpose, crab mode is meant to help you navigate the Hummer through trails it might otherwise be too big to fit through using regular steering. In reality, we suspect most folks might use crab mode in the exact same fashion as GM did this past weekend: to impress people. And honestly, we canÂ’t blame them. It was a seriously cool sight to see. Crab mode in action: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

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

Junkyard Gem: 1990 GMC S-15 Jimmy 4x4

The General sold the GMC-badged version of the first-generation Chevy S-10 Blazer, known as the S-15 Jimmy or just the Jimmy, from the 1982 through 1994 model years. These trucks were based on the small S-10 pickup and sold well (until small trucks were forced to get bigger and less truck-like after the dawn of the Ford Explorer-inspired commuter-truck era), but they have become difficult to find in vehicle graveyards in our current century. Here's a '90 Jimmy 4x4 with red-primer paint job, found in a self-service yard on California's Central Coast last month. GMC shoppers could get the 1990 Jimmy as a rear-wheel-drive truck, but this one has the four-wheel-drive option that allowed Tahoe-bound skiers to skip the chain monkeys on the way to the slopes (the CHP, understanding that California drivers have a 95% mortality rate on snow or ice, requires chains or four-wheel-drive to get over Donner Pass when there's a hint of snow forecast). GM sold so many millions of small-block Chevrolet V8s that it made economic sense to use the same tooling to produce a V6 version. The result was this truck's 4.3-liter V6 that was three-quarters of the good old Chevy 350 (5.7-liter) V8 that powered so many Camaros, Chevelles and Impalas. The 4.3 didn't make smooth power, but it got the job done and held together quite well. This one was rated at 160 horsepower, good enough for the Jimmy 4x4's 3,512-pound curb weight. These days, though, used-truck shoppers insist on at least two tons of heft plus four doors. Some discount lot in Monterey or Salinas couldn't even get $999 for this truck, and so it ended up in the final stop before the cold steel jaws of the crusher. 1990 was the last model year for the two-door-only Jimmy; for 1991, the Jimmy came with a choice of two doors (for devil-may-care types) or four doors (for drop-the-kids-at-school types). I've always liked the look of the instrument panels on the early S-10s and its siblings; even though the designers had to work within strict budgetary limitations, they made the panels look interesting. This truck nearly made it to 170,000 miles before the end. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. So powerful with the 4.3 (the regular S-15 pickup still came with a 2.8-liter V6 as base equipment) that it could destroy a TV camera.
