For uncompromised power and torque and unparalleled refinement, look
no further than the Vortec engine family. each model uses innovative
"vortex technology" to swirl and tumble the incoming air and fuel for optimum
power and response.

aCtiVe fUel ManaGeMent to conserve fuel when extra power isn't
needed, such as cruising at highway speeds, active Fuel Management (not
available on 6.0L V-8 [L96]) deactivates four of the eight cylinders to
become a V-4. For passing, trailering or mountain terrain, pressing the
accelerator can reactivate all eight cylinders in milliseconds. For even
greater power when necessary in Hybrid models, the electric drive system
can automatically engage for extra torque.
e85 fleXfUel CapabilitY
yukon Vortec V-8 engines are capable of running on e85 ethanol. this
advanced biofuel is a mostly renewable fuel that burns cleaner than gasoline
and helps to reduce vehicle emissions, as well as the need for imported oil.
VaRiable ValVe tiMinG (VVt) this feature monitors and changes valve
open and close points for near-peak levels of torque across the entire range
of engine speeds.
tRansMission
6-speed aUtoMatiC oVeRdRiVe tRansMission engineered for
control and confidence in a wide variety of situations, the 6-speed
automatic is standard in 1500 Series yukon models, including denali
(except Hybrid and denali Hybrid models). it's an ideal partner for Vortec
power. Filled with innovative technology, this transmission can help you cut
steep climbs, long grades and heavy loads down to size.
aUtoMatiC GRade bRaKinG Standard with 6-speed automatic
transmissions, this feature can be activated in tow/Haul mode—but
disengaged with driver Shift Control activated. Grade braking
automatically senses when you want to slow your yukon, and when the
conditions are met, engages a Grade braking shift schedule that helps
you maintain your desired speed.

this feature lets you move through the gears with the precision of a manual
transmission. Move the shift lever to "M," and you get fingertip "tap up/
down" control of transmission gear selection.
tow/haUl Mode this feature raises transmission upshift points, as well
as helps slow your yukon by raising downshift points, which helps you to
use engine compression to slow your yukon with less noise and harshness.

technology can store a lot of energy in a small space. in fact, the 300-volt
battery pack is strong enough to propel your yukon from rest to over 25 mph
on electric power alone, yet small enough to fit under the second-row seat
between the steel frame rails. this leaves your cargo space and passenger
capacity unchanged from other yukons.
hYbRid eleCtRoniCallY VaRiable tRansMission to conserve
fuel at low speeds or under light loads, this transmission has two integral
electronic motors that engage to give you smooth, effortless power.
at highway speeds or heavier loads with its 6.0L V-8 VVt engine engaged,
it acts as a normal automatic transmission.
ReGeneRatiVe bRaKinG sYsteM during normal deceleration, regenerative
braking uses the motors in the hybrid transmission as generators to slow
the vehicle by applying electrical resistance, rather than using brake
friction. at the same time, the motors are capturing that energy as
electricity in the 300-volt battery pack, making that energy available
for the next acceleration cycle.

onstaR VehiCle diaGnostiCs
knowing the condition of your yukon's key systems is as easy as checking
your e-mail. onStar Vehicle diagnostics is a service that is standard with
your 6-month trial subscription to the directions & Connections Plan and
can run hundreds of checks of your yukon's engine, transmission, antilock
brakes and more, then organize the information into an easy-to-read
monthly report. onStar can also run a check of your vehicle as you drive just
by pressing the blue button and asking the advisor for an on-demand
diagnostics check. that's peace of mind when you need it.
