Spy photos suggest more rugged GMC Sierra HD AT4X is on the way

Ford has the Super Duty Tremor. Ram has the Power Wagon. GM doesn't yet have a really serious heavy duty pickup off-roader, but these spy shots suggest that may be changing. They show a GMC Sierra HD with plenty of height, chunky tires and a prominent skid plate. We suspect it may be an AT4X trim, to slot above the somewhat trail-oriented AT4 already on sale. Despite the heavy camouflage on each end, we can see right away that this GMC has a new front bumper that's turned up at each end, likely to leave some space for getting tires up to obstacles. There doesn't appear to be the air dam that shows up on all other Sierra HD models, either. Under the front end is a very prominent skid plate. Other interesting aspects include the tires. They appear to be the same model of Goodyear Wranglers used on the Chevy Silverado 1500 ZR2, and not the ones currently in use on the Sierra HD AT4. Also, this extra rugged Sierra features a huge exhaust tip, which seems to confirm the Duramax turbodiesel V8 will be available, probably as an option over the gas V8. This is noteworthy since the Ram Power Wagon is only available with a gas engine. Of course the Ford Super Duty Tremor is available with both gas and diesel engines. The regular Sierra 1500 AT4X was only just revealed last October for the 2022 model year. So we would expect that this heavy duty version would make an appearance for either the 2023 or 2024 model year of the model. It could accompany a light refresh of the truck, again similar to the lighter duty model. We expect it will also feature some additional suspension and drivetrain upgrades to help it compete with the Ford and Ram off-roaders. Related video: This content is hosted by a third party.

Chevy Silverado, GMC Sierra 4.3-liter EcoTec3 V6 nets 18 mpg city, 24 highway

There is no doubting that fuel economy has become an important factor in the highly competitive fullsize truck market, with the Ford F-150 EcoBoost V6 and Pentastar V6-powered Ram 1500 setting quite a precedent in recent years. Now it's General Motors' turn. The General has just announced that the new base V6 used in the 2014 Chevrolet Silverado and GMC Sierra 1500 models will return an EPA-estimated 18 mpg city and 24 mpg highway in two-wheel drive trim, regardless of cab configuration.
While these figures don't go so far as to earn GM any "best-in-class" fuel economy claims (thanks to the 25-mpg Ram 1500 HFE), this new 4.3L EcoTec3 V6 does edge the F-150 and Toyota Tundra while boasting best-in-class numbers for torque, payload and towing capacity among six-cylinder rivals. This all-new engine produces 285 horsepower and 305 pound-feet of torque, and it gives the 2014 Silverado and Sierra the highest towing rating among standard V6 models with a 7,200-pound towing capacity - besting the Ram by 700 pounds, the base F-150 by 1,100 pounds and coming within 200 pounds of the V8-powered Nissan Titan.

MotorWeek looks back at 1995 Chevy Tahoe, GMC Yukon

MotorWeek's Retro Review series gives us a nostalgic look back at some of the best sports cars and luxury sedans available in the 1980s and '90s. For its latest clip, the show shifts gears to remember the 1995 Chevrolet Tahoe and GMC Yukon. Similar to the success of crossovers today, SUVs were tallying big sales and making big money for automakers in the mid-'90s. The Tahoe and Yukon filled slots in the market as steps down from the larger Suburban. These twins weren't wanting for space, though, with plenty of room to haul around a family. MotorWeek came away generally impressed too, and called the models some "of the better riding sport utilities we've ever experienced." This review comes with some jazzy, electric guitar licks to enjoy in the background.
