GMC Sierra Denali CarbonPro bed is finally, almost here

GMC revealed the Sierra 1500 with the optional CarbonPro bed on March 1, 2018. The bed wasn't available at launch, though. You can't buy it now, either, but it will hit dealerships with limited availability after production starts in early June, exclusively for the Denali 1500 and AT4 1500 trims. The carbon floor and sides replace the steel panels in a normal bed, providing "strength, durability, and scratch resistance" and a potential 59-pound weight saving, depending on the truck's configuration. To make sure the bed had a chance, development engineers replicated "extreme use scenarios" like dropping 1,800-pound gravel loads, 450-pound steel drums, and cinder blocks from various heights. They put a 250-pound man on a snowmobile with studded tracks, had him drive into the bed and then go wide-open throttle. We're told the result was "minimal scratching." On top of the extreme weather testing any vehicle goes through, the team also put a generator in the bed and aim the exhaust into a corner to ensure vibration and direct heat wouldn't deform the carbon fiber. Because of the finer shaping area-specific strength possible with carbon fiber, the bed provides one cubic foot of additional payload space by having its sidewalls pushed further out. The CarbonPro bed doesn't need a bedliner, and is grained at the top for better traction but smooth on the bottom for easier hosing down and dirt removal. Tie-downs at the front of the bed work with molded indentations to hold motorcycle tires, and slots in the sidewalls hold two-by-sixes. The truck maker says the carbon-lined payload area confers "best-in-class dent, scratch and corrosion resistance," but we suppose the nation's pickup truck army will prove that or not. The trucks likely won't have the hardest life at the start, since the Sierra Denali costs $56,790 before even a basic option like four-wheel drive. The real test probably won't come until around 2029, when third owners begin treating their aerospace-inspired thoroughbreds like dray horses.

GMC's electric, 1,000-horsepower Hummer SUV makes a surprise appearance

We knew the GMC Hummer pickup would spawn an SUV, but we didn't expect to see it so soon. It quietly appeared in a marketing presentation about electric cars that General Motors streamed online in November 2020. The camera never focused on the SUV, there was always an executive sitting in front of it, but we see enough to tell it's closely related to its pickup sibling. Both battery-powered off-roaders are nearly identical from the tip of the front bumper to the edge of the rear doors. The SUV's overhang is a little bit shorter than the pickup's, though there's presumably space for a third row of seats. Its rear end doesn't appear in the presentation. Nothing suggests GMC made major powertrain changes to the SUV, so it's likely identical to the truck underneath the sheetmetal. Range-topping models will receive three motors zapped into motion by a 24-module Ultium battery pack. Motorists will have 1,000 horsepower and approximately 350 miles of driving range to play with. GMC plans to start building the Hummer pickup in late 2021, and the SUV might not enter production until early 2022. We expect pricing will initially start above $100,000, but more affordable variants will gradually join the lineup during the first half of the 2020s. When it lands, the off-roader will compete directly against the Rivian R1S. General Motors will invest $27 billion into electric and autonomous cars by 2023. Its portfolio of EVs will also include a Silverado-sized pickup, a crossover based on the Bolt, and a high-end Cadillac crossover named Lyriq. "We want to be number one in EVs in North America," affirmed company boss Mary Barra.

Hacker jury rigs Amazon Echo into voice-controlled remote start

A lot of automakers have smartphone apps to start, lock, or unlock a connected car. Some automakers will even let you do that with a smartwatch. Then, there's YouTube user Jryanishere, who decided to use Amazon's chatty Echo voice-controlled, internet-connected information thingy. Yes, we said thingy, because we aren't really sure how else to describe the Echo. While the Echo system has received a hearty ad campaign – featuring Alec Baldwin asking Amazon's virtual assistant, Alexa, questions and ordering socks – we think this might be the first really useful thing we've seen it do. Using a MacBook, a Raspberry Pi, an Echo, an OBDLink plug-in, and his 4G LTE-equipped GMC, Jryanishere has basically made a voice-controlled remote-start system. Now, like so many voice-controlled things, this strikes us more of an extravagance than something that's functionally worthwhile. After all, the remote start on the a GMC keyfob isn't exactly rocket science. You can check out the Echo in action up top. Jryanishere gives a pretty thorough breakdown of how the setup works in the video above, but if you're at all into this sort of technological mischief, you'll want to watch (and check out the hilariously detailed blog explaining the job).
