Could the GMC Jimmy come back as a Wrangler fighter?

Every three or four years, two cars go into heavy media rotation in stories about supposed new competitors. The headlines go something like, "X automaker working on a vehicle to fight the iconic Y." The Y cars are the Porsche 911 and the Jeep Wrangler. For this story, the X automaker is GM. And since GM already has its 911-fighter poised for debut next month, we speak here of the Wrangler. Car and Driver writes that GMC might take another shot at a Jeep challenger, this time by rebirthing a body-on-frame Jimmy SUV. For any who don't know, GMC sold an S-15 Jimmy from 1982 to 2005, a twin of the Chevrolet S-10 Blazer. Those SUVs started their lives as the Chevrolet S-10 and GMC S-15/Sonoma pickups. The Blazer name has returned to the light, albeit without its old-school rugged manners. There's still an opening on the GMC side, though, so C/D says the idea would be to work that old magic on the GMC Canyon pickup. The report is more chaff than grist for the rumormill, with liberal application of phrases like "looking to come up with," "could be," "could take," and "could arrive." Having said that, a potential Jimmy model could come in a few years, could use the same six-cylinder gas and four-cylinder diesel engines as the Canyon, and could start around $30,000. The Jimmy could wear GMC's new mud-and-guts AT4 trim name, or become a mud-and-guts trim for the Canyon just as the ZR2 is for the Colorado. It's not an entirely crazy idea, however, when a body-on-frame Trailblazer SUV based on the Colorado sells in Latin America, Asia, and Australia and does pretty well in the mud and muck. GM's been on the edge of going to war with the Wrangler for at least 12 years, when a Hummer exec said the HX concept would debut at the 2008 Detroit Auto Show and go on sale in 2010 as the H4. In 2015, The Wall Street Journal said GM was canvassing GMC dealers about something to get in the ring with the Wrangler. And all that was before every other automaker had to watch Jeep open a money-counting operation to handle its Wrangler profits, and dealers started charging $20,000 markups on Gladiators. In May, spy shooters caught a sensor-laden Jeep running at GM's Milford Proving Grounds in Michigan. Earlier this month, Bloomberg reported GM is considering a Hummer revival as an all-electric hardcore SUV. So we will not be surprised if GM rolls out a Wrangler fighter in the near-ish future. But we won't be surprised if GM doesn't, either.

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:

GMC Sierra spied with ZR2-style off-road modifications

A few months ago, the 2022 Chevy Silverado ZR2 was revealed with a bunch of off-road goodies to help it achieve a little more parity with trucks like the Ford F-150 Raptor and Ram 1500 TRX. But GM has another full-size truck, the GMC Sierra, and it would seem silly to us if the company didn't share those parts. Based on these spy photos, it seems GM agrees. Though thoroughly camouflaged, we can tell this truck is a GMC Sierra thanks to the sheetmetal on the doors and the distinct shape of the wheel arches. Under the wrappings, we can see that this Sierra features a very different front bumper to the current king of Sierra off-road models, the AT4X. The bottom edge is much higher for better clearance, particularly on the sides in front of the wheels. This is the same type of change applied to the Silverado ZR2's front end. It does appear to be missing the ZR2's skid plate, though we suspect that's a temporarily missing component on this prototype. One other off-road upgrade this Sierra features is a pair of rock rails to protect the rocker panels on the cab. What we can't see are the shocks installed on this truck. If this is a GMC version of the ZR2, it should have the spool-valve shocks from Multimatic. They're some of our favorite suspension components on any vehicle. Other components it should have are locking front and rear differentials, 33-inch tires and a standard 6.2-liter V8. Since the Silverado ZR2 is already revealed and ready for production, we would expect to see the GMC version soon. A good bet would be for a reveal in time for the 2023 model year. As for a name, it's hard to say, since we've already had AT4 and AT4X. It could be named something completely separate from the AT4 line. Related Video: This content is hosted by a third party.
