THE MOST SCIENCE IN ITS CLASS.
yukon Hybrid is the first full-size SUV to offer two-mode hybrid drive. Together with yukon Denali Hybrid,
they use the breakthrough technology of the Power Control Management System that seamlessly
transitions between fuel and electric power. The result is a 33 percent improvement in EPA-estimated
fuel economy during city driving over the non-hybrid model.
trailering capacity,
along with undiminished interior cargo volume and passenger seating capacity.

At low speeds and light loads, yukon Hybrid can reduce fuel consumption by shutting off the engine
and operating on electric power alone. It can also run on engine power alone, or a combination of both
gas and electric. In the city, this technology offers an EPA-estimated 20 mpg, the best in its class.
With the advanced technology of Active Fuel Management (see below) at highway speeds, yukon can
use its 6.0L V-8 VVT engine in either V-4 or V-8 operation—sometimes with an extra boost of electric
power—as conditions warrant. Full V-8 power is available for trailer towing, passing or pulling on a
long, steep grade. In other words, you have all the power you need, when you need it, while still main-
taining excellent fuel economy — an EPA-estimated 23 mpg on the highway.

During normal stops, regenerative braking uses the motors in the hybrid transmission as generators
to decelerate the vehicle by applying resistance in the motors rather than brake friction. At the same
time, the motors are capturing that energy as electricity in the 300-volt battery pack, electricity
that is available for the next acceleration cycle.

In situations where extra power isn't needed, such as cruising at highway speeds, AFM deactivates
four of the eight cylinders to become a V-4. For passing, trailering or hilly terrain, pressing the
accelerator can reactivate all eight cylinders in milliseconds. For even greater power when necessary,
the electric drive system can automatically engage for extra torque.

To give you maximum
power over the widest
range of engine speeds,
VVT changes the engine's
performance profile to
match the driving situa-
tion. In city driving, VVT
gives you a smooth idle
and quick response at
low speeds. On the open
road, VVT changes your
engine to a bold, high-
performance V-8 with
horsepower to spare.

yukon Hybrid packs a
lot of power in a small
space, thanks to its 300-
volt Nickel-Metal Hydride
(NiMH) battery pack. Its
technology stores power
so efficiently that the
complete battery pack
fits under the second-row
seat between the strong
steel frame rails, leaving
your passenger and cargo
volume unaffected.
