2022 GMC Hummer EV dimensions, clearances and off-road features explained

There are two things that almost everyone immediately thinks of when they hear the word "Hummer." And they are size and off-road capability. Looking at the numbers on the 2022 GMC Hummer EV, it seems the electric pickup has literal truck loads of each. One of the most prodigious numbers is the truck's width. See those clearance marker lights on the roof? They aren't just there for style, they're required by law due its width. At 86.7 inches, it's just a bit wider than a Ford F-150 Raptor, which is itself 6.4 inches wider than a comparable F-150. The Hummer is also 5.5 inches wider than a GMC Sierra. Length is more reasonable at 216.8 inches, which is much less than a full-size crew cab pickup (a Sierra 1500 is 231.7 inches with its 5-foot-8-inch box or 241.2 with the 6-foot-6 one). It's even 3 inches less than the Raptor SuperCab and only 4.4 inches longer than a GMC Canyon with the standard 5-foot-2-inch box. In other words, the Hummer EV is roughly as long as a midsize pickup but is wider than a heavy-duty one.  What does that mean for the cabin? With 38.9 inches of rear legroom, it falls well short of a Sierra Crew Cab's 43.4, but it's important to remember that crew cab pickups have an overkill amount of limo-like legroom. The Hummer's amount is still 3.7 inches longer than a Sierra Double Cab and 3.1 inches longer than a Canyon Crew Cab. Headroom, which was rather pathetic in the old Hummer H2, is 38.6 inches in the back seat – less than both its GMC truck siblings, but not by much. In other words, there should be plenty of space back there. Note that GMC didn't indicate bed length, frunk volume, or importantly, curb weight. We will update this should we find out answers to any of those.  Although it's big, the Hummer has plenty of features to make it nimble off road, both traditional and high-tech. One of the primary features is the height-adjustable air suspension, which offers 13 inches of travel and automatically adjusts damping for driving conditions. It has three main levels, a lowered setting for Aero Mode that helps with improving highway energy use, a default height for the normal driving modes, and a higher setting for the off-road Terrain Mode.

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.

Poor headlights cause 40 cars to miss IIHS Top Safety Pick rating

Over the past few months, we've noticed a number of cars and SUVs that have come incredibly close to earning one of the IIHS's highest accolades, the Top Safety Pick rating. They have great crash test scores and solid automatic emergency braking and forward collision warning systems. What trips them up is headlights. That got us wondering, how many vehicles are there that are coming up short because they don't have headlights that meet the organization's criteria for an "Acceptable" or "Good" rating. This is a revision made after 2017, a year in which headlights weren't factored in for this specific award. This is also why why some vehicles, such as the Ford F-150, might have had the award last year, but have lost it for this year. We reached out to someone at IIHS to find out. He responded with the following car models. Depending on how you count, a whopping 40 models crash well enough to receive the rating, but don't get it because their headlights are either "Poor" or "Marginal." We say depending on how you count because the IIHS actual counts truck body styles differently, and the Infiniti Q70 is a special case. Apparently the version of the Q70 that has good headlights doesn't have adequate forward collision prevention technology. And the one that has good forward collision tech doesn't have good enough headlights. We've provided the entire list of vehicles below in alphabetical order. Interestingly, it seems the Volkswagen Group is having the most difficulty providing good headlights with its otherwise safe cars. It had the most models on the list at 9 split between Audi and Volkswagen. GM is next in line with 7 models. It is worth noting again that though these vehicles have subpar headlights and don't quite earn Top Safety Pick awards, that doesn't mean they're unsafe. They all score well enough in crash testing and forward collision prevention that they would get the coveted award if the lights were better.
