GMC teases Hummer EV's removable roof panels

Today was supposed to be the day that GM took the wraps off its GMC Hummer EV. We were told as much during the Super Bowl commercial, but GM revised it to an undecided future date, citing the coronavirus as the reason. Instead of the big reveal, we have a teaser.  The Hummer EV is going to feature removable roof panels, and now we get a better look at them. There are four roof panels and a front T-bar that come out of the truck. You can see what that looks like in the video at the top of this post. Comparisons to Jeep are obvious as the open-air experience is likely similar to the Gladiator and Wrangler with their hardtop roof panels removed. That zero-limits slogan makes a bit of sense from this respect. With the sheer number of roof panels, we suspect a single person will be able to remove them alone. In addition to the video of the roof, we get a small peek at the massive digital screens the Hummer will be sporting. Check them out at the bottom of the photo below. They appear to be two large slabs, separate from each other. Other details are scarce on the ground. We’re not sure when the Hummer will make its grand entrance at this point, but are still excited to see the 1,000-horsepower truck hit the road. GMC is still advertising the 0-60 mph time of just 3 seconds, too. The latest tidbit of news suggests that further teasers might be coming, so we could be in for a rather drawn out reveal process. Our senior green editor John Snyder got to see the GMC Hummer in person earlier this year at GMÂ’s EV Day and described it like this: “ItÂ’s a big, off-road-ready pickup complete with giant all-terrain rubber and tow hooks. It features removable roof panels for access to the open sky, which appears to be depicted in the teaser above. It features sail panels behind the C-pillars, similar to those on the Chevy Avalanche and Honda Ridgeline. Its bed was concealed with a tonneau cover, but it sported GMCÂ’s MultiPro tailgate that we first saw on the Sierra Denali. Interior photos showed a spacious interior with blocky shapes, squared hourglass vents that mirror the look of the taillights and a lunar theme that incorporates the topography of the Sea of Tranquility into things like the floor mats and speaker covers. It also has a large infotainment screen as well as a digital instrument panel.” Related video:

2019 GMC Sierra spied sporting just a thin wrapping

A new Chevy Silverado is on the way, and along with that comes it's fraternal twin, the GMC Sierra. We've seen spy shots before, but, like the Silverado we saw a few days ago, this is our best look yet. Nearly all of the loose-fitting camouflage has been removed, giving us a decent view of the bodywork. A brief look shows that the Sierra and Silverado will have significant styling differences for this generation. In the past, GMC trucks have been little more than rebadged Chevrolets. That's been changing in recent years, and the divide seems to be growing larger. The grille looks much larger than the Silverado's and there appears to be a small inlet right where the hood meets the front. From the side, we can see that the two trucks have different fenders and beds. The wheel wells on the GMC are squared off at the rear. Compare that to the round wells on the Chevy. Out back, the design is far more similar. Both trucks appear to have rear-facing exhaust outlets. The taillights, too, look to have close to the same shape. A big bulge in the center of the tailgate likely hides a large GMC badge. We still don't have a firm reveal date, but look for some further news this auto show season. Related Video:

GM recalls 3.8 million vehicles in North America due to braking issue

WASHINGTON — General Motors Co said Wednesday it was recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and that has been linked to 113 accidents and 13 injuries. The recall covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles. In late June, GM recalled 310,000 vehicles in Canada for the same issue. GM did not immediately explain why the Canadian recall occurred more than two months before it called back the vehicles in the United States. The recall was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted on Wednesday. The NHTSA opened a preliminary investigation into the issue last November, and said it had reports of nine related crashes and two injuries. It provided GM in July with additional field reports that prompted the automaker to open an investigation. GM said it could affect braking in "rare circumstances." The NHTSA said in a statement the "vehicles may experience brake boost failure, which would require increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance." GM said dealers will reprogram the electronic brake control module to improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Separately, GM said on Wednesday it is recalling 270,000 additional U.S. vehicles in three smaller recalls, including 177,000 2018 Chevrolet Malibu cars with 1.5L turbo engines because an error in the engine control module software may result in the fuel injectors being disabled.
