GM reportedly developing 2.5-liter turbo four-cylinder

General Motors is allocating a massive amount of resources to developing electric technology, but it's not forgetting about the gasoline-powered cars that make up the bulk of its sales. It's reportedly designing a new 2.5-liter turbocharged four-cylinder engine based on its 2.7. Citing "sources familiar with the matter," enthusiast website GM Authority wrote that the 2.5-liter four is "in [the] final stages of development," meaning it should be announced sooner rather than later (assuming the report is accurate). Technical details are few and far between as of writing. The publication learned that the 2.5 will be part of the Cylinder Set Strategy (CSS) family of engines and that it will be mechanically related to the 2.7-liter currently found in the Chevrolet Silverado 1500, among several other models. It will feature dual overhead camshafts. It's too early to tell which models the 2.5-liter four-cylinder will end up in, or how much power it will generate. The output will likely depend on the application. For context, the 2.7 delivers 310 horsepower at 5,600 rpm and 348 pound-feet of torque between 1,500 and 4,000 rpm in the Silverado. In the smaller Colorado, it provides anywhere between 237 and 310 horsepower depending on the trim level selected. While this is pure speculation, our crystal ball tells us the engine will end up powering crossovers. It's an easy deduction to make. We can't imagine it will be offered in the Silverado, and seeing it in the Colorado is unlikely because its entry-level engine develops 237 horsepower; there's likely not much of a market for a midsize truck with 200 or so horsepower. Putting it in the Corvette wouldn't make sense and the Camaro has nearly reached the end of its life cycle without a successor planned. This leaves us with Chevrolet's range of crossovers, like the Equinox, as well as their GMC-, Buick-, and Cadillac-branded counterparts. We're not discounting the possibility that the cars set to receive the 2.5 haven't been unveiled, but those are likely crossovers, too; the odds of seeing another big Chevy sedan are very, very low. General Motors hasn't commented on the report, and it hasn't publicly announced plans to expand its CSS family of engines. If the report is accurate, we should learn more about the new turbocharged, 2.5-liter four-cylinder engine in the not-too-distant future.

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:

GMC offers more 2024 Hummer EV SUV details, photos

GMC has shared more details about its 2024 Hummer EV SUV after its debut during the NCAA Final Four tournament. The SUV which follows the Hummer EV pickup, is smaller, more maneuverable and has a few features the truck doesn’t. GM says itÂ’s meant to strike a balance between off-road capability and on-road driving. GM also says Edition 1 reservations are already sold out. Compared to the truck, the Hummer SUV has a wheelbase about 9 inches shorter. With four-wheel steering, its turning circle is just 35.4 feet, which GM emphasizes is tighter than that of the Ford Mustang Mach-E (38.1 feet). ItÂ’s also less than the Hummer pickupÂ’s 37.1-foot turning circle. The SUV, which, at 196.8 inches long, is 20 inches shorter than the truck overall. It also features a much shorter rear overhang, at 35.5 inches. While thatÂ’s all helpful maneuvering through city traffic or suburban parking lots, it also provides advantages off-road. It has an approach angle of 49.6 degrees, a 49.0-degree departure angle and a 34.4-degree breakover angle. Suspension travel is 13 inches front and rear, with 16 inches of maximum ground clearance thanks to its Extract Mode that temporarily raises the vehicle to get out of tricky terrain. It can ford water 32 inches deep. It also features the same CrabWalk mode as the pickup. Available Ultravision provides 17 cameras, including underbody views to help navigate the trail. The Hummer SUV benefits from an enclosed cargo area behind the second row of seats. It still features the Infinity Roof with removable panels above the two seating rows to essentially turn the SUV into a convertible. At the rear is a swing-out tailgate that opens wider than the width of the vehicle. A spare tire rides on the tailgate as well. With the rear seats folded, cargo volume peaks at 81.8 cubic feet.  Additional hidden storage space is found below the recycled rubber floor mat, which features a design inspired by the moonÂ’s Sea of Tranquility (that's where Apollo 11 landed). As for technology, the Hummer SUV gets a 13.4-inch infotainment screen, plus a 12.3-inch instrument display in front of the driver. Fourteen cameras come standard, and the aforementioned Ultravision provides a total of 17 cameras, including a surround view. The MyGMC mobile app offers satellite rendered trail maps that can also help manage energy consumption off-road and make sure you have enough juice to make it to a charger when finished.
