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:

2024 GMC Acadia to go big again for third generation

In July, spy shooters caught prototypes of the next-gen GMC Acadia wrapped up tight in camouflage. We couldn't make out any useful aspects but one: The coming third-gen Acadia is larger than the current second-gen. Remember, GMC debuted a smaller Acadia for the 2017 model year, lopping eight inches of length and three inches of width from the first-gen large mid-size SUV to create a smaller mid-size three-row SUV. The new prototypes appeared to show that decision would be reversed, now we have proof thanks to more comments unearthed from GM's recent Investor Day presentations in New York. Caught by GM Authority, automaker president Mark Reuss said, "Alongside the Traverse, we’ll move the GMC Acadia to a little bit different size standpoint. This comes in a little bigger than the old Acadia, so itÂ’s a big transformation for GMC and its part of the market." In a 2016 Automotive News piece about how GMC planned to increase sales volume, AN reported, "One potential avenue: venturing into Jeep's terrain. Industry sources believe GMC is drawing up plans for an SUV based on the same body-on-frame platform that serves as the bones of the GMC Canyon and Chevrolet Colorado midsize pickup. It's in the early stages — it doesn't appear to have been sourced to suppliers yet and the SUV's arrival isn't expected until 2020 or later." The first-gen 2016 GMC Acadia was 200.8 inches long, while a 2016 GMC Canyon Crew Cab with the roughly 5-foot bed was 212.8 inches long. It's thought that truncating the second-gen GMC Acadia to 193.4 inches long and 75.4 inches wide was intended to leave plenty of room for the planned SUV on the Canyon platform. However far that SUV project got, it was reportedly canned in 2018.   Hence an upsized Acadia returns. Reuss' comment about the Chevrolet Traverse could imply what's coming for the GMC, the Chevrolet being 205.9 inches long and 78.6 inches wide. A bigger Acadia could make a better sales proposition against the two-row Terrain, too. The Terrain costs almost $9,000 less than the Acadia and is 182.3 inches long and 72.4 inches wide. It's not clear when GMC plans to show the new Acadia, but the consensus is that it will go on sale for the 2024 model year. Expect an all-new cabin, Super Cruise capability and a front fascia reminiscent of the new Canyon. Powertrain options are a mystery.

GMC Syclone spools up a storm on Jay Leno's Garage

A storm was brewing on American roads in the early 1990s. That's when Detroit's automakers were producing some of the hottest performance trucks ever devised – models like the Ford Lightning, GMC Typhoon, and its flyweight pickup sibling, the GMC Syclone. Jay Leno just happens to have one of the latter in his garage, and took it out to showcase in this latest video segment. The Syclone was an exercise in absurdity, and could not only trounce any other pickup on the road, it could outrun anything else GM made and just about anything else on the road – beating Ferraris and Porsches off the line. In a pickup, for crying out loud. The kicker is that its engine wasn't such a monster, either: under the hood sat a 4.3-liter turbocharged V6 pumping out what would seem by today's standards to be an adequate 280 horsepower and 350 pound-feet of torque. Even the smaller of the EcoBoost V6s available in today's Ford F-150 produces more than that. But in a lightweight, compact pickup, those figures were enough to propel the Syclone to 60 in 4.3 seconds and run the quarter-mile in 13.6 seconds. Long before the dune-jumping Ford F-150 SVT Raptor or even the Viper-powered Dodge Ram SRT-10, GM made fewer than 3,000 Syclones based on the compact Sonoma (sister to the Chevy S-10) and another 4,700 of the Typhoon, which was mechanically similar but more practical (albeit heavier) wagon bodywork from the Jimmy. But as Jay aptly points out, the Syclone was the one you wanted. Scope it out in the ten-minute video clip above.
