Stats Closeup Comparison Via Car and Driver: 2021 Chevy Tahoe Vs. GMC Yukon

The very latest Chevy Tahoe and GMC Yukon have just lately been announced, much to the delight of large SUV lovers everywhere. Both are slated to come out this summer as 2021 models, and the only real difference between the two was the badge. For these models, when you closely compare as Car and Driver did on their blog last week, you'll find some unique styling cues and features. After checking out this comparison, you can base your choice on which aesthetics and personality bits suit you best.

The two vehicles ride on GM's newest T1 truck platform, which also is present under the Chevy Silverado and GMC Sierra pickups. Both brands' new SUVs are larger than their predecessors on the outside and have more space on the inside. The Yukon and Tahoe get a 10-speed automatic transmission across the board, with three engine choices. The base engine is a 5.3-liter V-8 that makes 355 horsepower and 383 lb-ft of torque, and there's also a 6.2-liter V-8 cranking out 420 horsepower and 460 lb-ft of torque. Both are brought over from the last generation of Yukon and Tahoe, but the new versions brandish smarter cylinder deactivation systems and stop/start systems.

There's also a third engine choice: a turbodiesel 3.0-liter inline-six that made its first appearance on the Silverado and Sierra pickups. This engine delivers 277 horsepower and 460 lb-ft of torque, with the ability to post a 30-mpg highway EPA fuel-economy rating. The Yukon is now the recipient of an advanced drive system dubbed Active Response 4WD, which puts to use an electronic limited-slip differential that manages all-important traction and power distribution levels. This system is also used in the very performance-rich scenarios of the Corvette and Camaro and is one trait that makes the Yukon the better choice for off-roading and low-grip situations.

On the new models, the only similarities in the exterior design are the nearly identical top-down and side views. Other than that, the grille on the Tahoe is wider, and the headlights are now much narrower and higher up compared to the Yukon. In the rear, the SUVs now sport markedly different liftgates and taillights, which were nearly identical on the outbound models. For the Yukon on every trim except for the high-end Denali, the climate control panel, screen setup, and switchgear are the same on both SUVs. The differences lie in the badges on the steering wheel, interior color schemes, and trim materials themselves.

There is a completely different dashboard setup on the Yukon Denali, as the screen now sits lower on the dash and there are two larger HVAC vents just above it. The Denali model also boasts much nicer leather and wood materials. After you visit us here at O'Rielly Chevy of Tucson for a test drive, you'll also notice that both SUV models include optional air suspensions, 15-inch head-up displays, active grille shutters, and a list of safety and driver-assist features. When spring hits, there will be nothing more satisfying than having the family in tow while enjoying the best in comfort and go-anywhere quality that this pair offer up with pride!

RST Special Edition Prepares the Tahoe and Suburban to Tremble the Tucson Streets

The Suburban and Tahoe are able and trustworthy vehicles: they are known for their excellent ability to haul, climb and transport anyone from the little league to the debate club in style. The RST is designed specifically for drivers who want the coveted and current street performance look, without having to skimp on the capability or other trusty qualities of this vehicle. You can now come on down to O'Rielly and check out how awesome a few new modifications are: when you opt for the Performance Package, it includes a 420-hp, 6.2L V-8 engine, Magnetic Ride Control with performance calibration and an all-new Hydra-Matic 10L80 10-speed automatic transmission.

The RST will be available on Tahoe and Suburban models during the fall this year, and is heavily inspired by trends prominent in the aftermarket arena. All of the previous chrome trim has been eliminated, part of what gives the vehicle a simplified and able appearance. The bod-color grille surround and door handles have also been changed as well as gloss-black grille and mirror caps, black roof rails, window trim, badging, as well as the trademark Chevy bowties. The RST also includes the very able and sturdy 22-inch wheels for traction, nicely gift-wrapped in Bridgestone P28/45R 22 tires.

Even though these vehicles are perfectly equipped to hit the road on an arid and sun-kissed Tucson weekend, there are also a few other upgrades that will make the RST even more appealing to you. There is an available Borla performance exhaust system that offers a 20 percent boost in exhaust flow, resulting in a 7-10 horsepower gain from the rear wheels. Some drivers are finicky about their braking capabilities and the RST also can be beefed up with a front red Brembo six-piston, fixed aluminum brake caliper package that provides an 84 percent increase in brake pad area. Duralife rotors feature a hardened surface that will allow you to come to a stop more quietly, and with less vibration.

When you come visit us to check out the Performance Package, we'll show you how you can heftily beef up your street presence with a stealth performance calibration Magnetic Ride Control, 6.2L V-8, and the brand new 10L80 10-speed automatic transmission. This is the first time ever that the Tahoe features the 6.2L V-8, and you'll notice right away the difference with delivery of 420-horsepower and 460 lb-ft of torque.

Don't worry if you're helping out your contractor buddy, or planning a spur-of-the-moment trip to the lake: the Tahoe RST Performance Package will have the ability to tow 8,400 pounds, and get up to 60 MPH in less than 6 seconds. There's even more reason to set your sights on these two popular vehicles this year, and see how excited you'll be to have fun in a brand new one right around the time school is back in session. The Fall brings the promise of abundant change, and the RST will no doubt supercharge your daily schedule.
