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!
