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.

GM crab walked the Hummer EV truck up and down Woodward this weekend

Sometimes, manufacturers like to show off their fancy new wares at the Woodward Dream Cruise. It’s largely done through static showcases with big displays for the public to gawk at. However, GM did something a little different with its GMC Hummer EV truck this year. Instead of parking it at the Chevy and GM display area, it took to Woodward Avenue itself to show off the Hummer in pre-production form. Not only did GM drive the electric truck on the road in front of thousands, but it crab walked the whole way. This was our first time, and probably most of the publicÂ’s first time seeing the Hummer EV crab mode in person. Judging from the crowdÂ’s reaction (GM got its wish of everybody paying attention), folks are impressed, and maybe a bit confused at the HummerÂ’s sideways movements.  ItÂ’s a strange spectacle to see in person. At first, the truck appears as though itÂ’s sliding sideways on ice in a smooth, graceful slide. ThatÂ’s because even though the wheels are turned, the front of the truck is still pointing dead straight ahead. The GM employee behind the wheel of the prototype appeared to be moving forward at about 5-10 mph — it appears shockingly quick in person for the way this behemoth of a truck presents itself. The tech making it work is rather simple in concept. GM simply took existing rear-wheel steering technology, then amplified and modified it for this type of movement. Whereas most cars with rear-wheel steering max out at around 5 degrees of lock with the rear wheels, this Hummer can turn the wheels up to 10 degrees. Turn the wheel left or right in crab mode, and the Hummer moves diagonally down the street. If you use it for its intended purpose, crab mode is meant to help you navigate the Hummer through trails it might otherwise be too big to fit through using regular steering. In reality, we suspect most folks might use crab mode in the exact same fashion as GM did this past weekend: to impress people. And honestly, we canÂ’t blame them. It was a seriously cool sight to see. Crab mode in action: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Redesigned 2021 GMC Yukon gets a diesel, AT4 model, Denali-exclusive interior

GMC's most robust family hauler is getting a complete redesign for the 2021 model year, including a new, off-road centric AT4 model, an upscale interior exclusive to its luxurious Denali model, an available air suspension, and, last but not least, a diesel engine.  With Americans obsessing over trucks, it's no surprise that GMC is going hard with its AT4s-for-everybody strategy; the Yukon is no exception. This will be the first model year for the new trim on GMC's largest SUV. This off-road model gets all the goodies you'll need to veer off the beaten path with confidence, including an extra 2.0 inches of ground clearance with the adaptive suspension option (more below), a two-speed transfer case, standard Goodyear all-terrain tires, an off-road mode for GMC's "Traction Select" drive mode system, hill descent control, and some extra underbody skid plates. Since GMC is a premium brand, even the AT4 gets some luxury appointments, such as a heated steering wheel, heated and ventilated front seats, and heated outboard second-row seats. The interior is also adorned in black leather with tan accents and "AT4" embroidery in the seat backs.  Speaking of premium, GMC will introduce an air-ride adaptive suspension with an off-road ground clearance mode as a late-availability option for several Yukon models, and this feature will be included on the Denali trim.  The Yukon and Yukon XL are GMC's variants of Chevrolet's full-sized SUVs, the Tahoe and Suburban. Their fundamental body-on-frame architecture is also shared with GM's half-ton pickup trucks, and thanks to that common engineering, they can also share powertrains. That's normally just a trivial side note when it comes to a new GM SUV announcement, but this time around, it's a bit more meaningful thanks to the introduction of a new light-duty, inline-six diesel in GM's truck lineup last year.  Yep, that means that for 2021, like the Tahoe and Suburban, the Yukon is getting a diesel option. The 3.0-liter Duramax makes the same 277 horsepower and 460 pound-feet of torque as it does in GM's trucks.  GMC's standard engine is still the 5.3-liter V8 that makes 355 hp and 383 lb-ft of torque. The 6.2-liter V8 is also an option like before, producing 420 hp and 460 lb-ft of torque. All engines come with a 10-speed automatic and a choice of rear- and four-wheel drive.
