2022 Chevy Tahoe, Suburban and GMC Yukon get updated transmission

General Motors' full-sized SUVs have slipped in one more change before the year turns. GM Authority reports that the 2022 Chevrolet Tahoe and Suburban, and the 2022 GMC Yukon and Yukon XL equipped with gas V8 engines, will pick up a revised ten-speed automatic transmission. The new unit carries RPO code MHS, and Chevrolet communications rep Catherine Scales told GMA the updated gearbox "allows our manufacturing and dealer teams to more easily align the specific calibration needed for the transmission and can enable OTA updates in the future." It seems GM wants to make it easier to update the transmission's tuning and calibration in the future with the automaker's networked Vehicle Intelligence Platform/Global B electronic architecture. The 10-speed auto comes bolted to the 5.3-liter V8 and the 6.2-liter V8. The 3.0-liter inline-six Duramax diesel continues with the 10-speed automatic already in use. To recap the other changes for the full-sizers, we'll start with the 2022 Tahoe and Suburban, which get a new 12.3-inch digital instrument display to replace the former 8-inch unit and physical gauges. Navigation will be standard equipment displayed on the 10.2-inch infotainment touchscreen on all trims barring the base LS. Lane-keeping assist and parking sensors are also now standard, while reverse automatic braking is added to the Enhanced Display and Alert package on the top trims. Finally, the 6.2-liter V8 option is expanded to the Z71, RST and Premier trim levels, but it requires selecting one or more packages on the Z71 and RST. Moving onto the 2022 Yukon, availability of the 6.2-liter V8 expands to the AT4 trim, and the big V8 comes with a shiny pair of exhaust finishers. Redwood Metallic paint joins the exterior color palette, more wheel options are on offer, and illuminated sill plates can gussy up the rocker panels . An Enhanced Trailering Technology Package adds 13 cameras with the option for an interior accessory camera for those with enclosed haulers. On the safety side, expect reverse automatic braking to join the list of available driver assistance features. Inside, the Yukon welcomes the 12.3-inch digital cluster, the Yukon Denali welcomes the power sliding console as a standard feature instead of a $350 option.  Related Video:

2018 GMC Terrain loses the V6 and gains a diesel for an all-turbo lineup

You may have noticed that compact crossovers are kind of a big deal these days. After eight years on sale, GMC is finally getting a new version of its littlest ute, the Terrain, for 2018. And it can't arrive a moment too soon. The 2018 GMC Terrain made its debut tonight on the eve of the 2017 Detroit Auto Show. The 2018 Terrain looks to be completely new, and is now built on GM's D2XX platform. It again shares a platform and major components with the Chevrolet Equinox; like the 2018 Equinox, the Terrain will offer three engines, including two turbocharged gas four-cylinders and a turbodiesel four. The base 1.5-liter gas four makes 170 horsepower and 203 pound-feet of torque, while the 2.0-liter inline-four puts out 252 hp and 262 lb-ft. (The 2.0 basically takes the place of the 3.6-liter V6 offered in the outgoing Terrain.) GM's 1.6-liter diesel four will also be available, making 137 hp and 240 lb-ft of torque in this application. Both gas engines will be paired with nine-speed automatic transmissions, while the diesel gets a six-speed auto. No fuel-economy claims have been made, but we expect the new models to outdo the current versions, with the diesel reaching around 40 mpg on the EPA highway cycle. View 14 Photos The new Terrain's design is equally fresh and does a good job of differentiating it from the related Equinox, with details very reminiscent of the new GMC Acadia. The lighting elements are even more intricate here, with LEDs used for the daytime running lights and taillamps. GMC designers gave it the floating-roof look, which is successful aside from the odd placement of a trim badge at the base of the D-pillar. Terrains will again be available in SL, SLE, SLT, and range-topping Denali trim, with the latter featuring the signature satin chrome grille, chrome accents, and monochrome paint scheme GMC uses on all of its top-trim models. The interior sees an upgrade in materials and a more-thoughtful layout, with a new version of GM's Electronic Precision Shift gear selector using buttons and switches instead of a lever to open up more space on the center console. Both front- and all-wheel-drive models get a Traction Select system that will tune the shift points and throttle points for specific driving conditions via a knob at the rear of the console. On models equipped with all-wheel drive, a front-drive mode disconnects the rear axle to improve fuel economy.

2025 GMC Yukon AT4 teased, will likely follow 2025 Suburban template

It's time to begin teasing the 2025 GMC Yukon, the luxury truck division doing so with a glimpse of the front fascia on the AT4 trim. This being a refresh, we're not looking for major changes to hard points. In contrast to today's Yukon, it seems the new face will stress horizontal breadth instead of highlighting the central aspect of a giant grille and skid plate area. Starting with the taller C-shaped headlights on the 2025, a shorter horizontal element at the top no longer reaches all the way to the grille surround, and it's separated from the three main beams below by a body-colored piece extending from the grille cradle. Below the light, a new lower bumper treatment probably increases the aggression compared to today's truck. Instead of black centerpiece that houses the skid plate and a pair of tow hooks, it appears the entire bumper will be black and wrap around into the fenders. Finally, the grille looks the same, but its crossbars have been reprofiled.  As sibling to the 2025 Chevrolet Tahoe and Suburban that Chevy revealed last November, we expect many of the same updates here. Outside, that would mean refinements to the independent rear suspension for more nimble handling, new wheel designs, and availability of the second-generation 3.0-liter Duramax inline-six with 305 horsepower and 495 pound-feet of torque instead of today's 277 hp and 460 lb-ft. Inside, we expect a new instrument panel housing a 17.7-inch touchscreen for infotainment, and a column shifter replacing the push buttons on the center console. Updated trim materials — along with the overdue infotainment upgrade — should provide a finer sense of luxury than what's currently on offer.  If tech treats carry over, buyers will have access to the Connected Cameras feature for viewing and recording inside and outside of the vehicle for crash and security purposes. An Interior Motion Detection system can detect "micro-movements" in the cabin that could signal a baby or a pet left in the vehicle.  The Yukon might go further than the Chevy SUVs, seeing that GMC has some birthdays to celebrate: 2024 is the fifth anniversary of the AT4 trim and the 25th anniversary of the Denali trim. We'll find out later this year, GMC promising the Yukon reveal sometime after the new Acadia begins shipping to dealers.
