2WD AND 4WD MODELS
In situations where you don’t need
extra power, such as cruising
down the highway on level roads,
Sierra Hybrid’s AFM deactivates
four of the engine’s eight cylinders.
When load demands increase,
all cylinders are reactivated to
provide eight-cylinder operation
and maximum power.
At the heart of this innovative
vehicle are traditional Sierra
strengths, including a Vortec
engine. In this case it’s the
6.0L V-8, using Variable Valve
Timing (VVT) to produce 332
hp and 367 lb-ft of torque.
Managing the on-the-fly blending
of engine and electrical propul-
sion is an electronically variable
automatic transmission.
The electric portion of the hybrid
system features a 300-volt nickel-
metal hydride battery pack that
fits neatly under Sierra’s rear seat
without compromising passenger
room or cargo space. When called
on, two motors integrated within
the transmission draw on battery
power to propel the vehicle.

The Sierra Hybrid automatically
and seamlessly selects the best
operating point for the powertrain
to deliver both fuel economy
and performance while also
reducing gear “hunting” associated
with trailering.
During normal stops, regenerative
braking uses the motors in the
hybrid transmission as generators
to decelerate the vehicle by apply-
ing 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 ac-
celeration cycle.
At low speed and with a light
load, Mode 1 can employ elec-
tric power alone, engine power
alone or a combination of both.
It reduces fuel consumption in
stop-and-go traffic by shutting
off the engine and operating on
electric power alone. The result is
an EPA-estimated 21 mpg in city
driving, a 40-percent improve-
ment over the traditional engine.
3
At highway speeds, AFM uses
either V-4 or V-8 operation
— some-
times with supplemental electric
power as conditions warrant. Full
V-8 engine power is used when
conditions demand it
— such as
passing, trailer towing or climbing
steep grades. On the highway,
Sierra Hybrid has an EPA-estimated
22 mpg.

XFE: thE drivE For Economy
ActivE FUEL mAnAGEmEnt (AFm)
With this advanced technology, all eight cylinders operate during starting,
idling and torque-intensive tasks like accelerating, hauling heavy loads
or towing. But in everyday driving, once Sierra has reached cruising
speed, AFM can temporarily deactivate four of the eight cylinders. A
sophisticated Engine Control Module (ECM) continuously measures load
conditions, including throttle input. Under light loads, it automatically
closes select intake and exhaust valves and cuts fuel delivery for half of
the cylinders. When the driver demands brisk acceleration or full torque
to move a load, the ECM activates all cylinders — within 20 milliseconds
— so full V-8 power is always right there, on tap. Transitions are virtually
indiscernible to most drivers. AFM helps Sierra XFE models offer the
best conventional engine fuel economy in its class.

Now standard on all Sierra 1500 models with Vortec 6.2L and 5.3L V-8 engines is an electronically controlled
6-speed automatic that combines high max trailering with precise control. Driver Shift Control (DSC) lets you select
a range of gears to suit variable driving conditions. Shift into “M” and the currently engaged gear number is
illuminated, and all other gears are accessible. As conditions vary, you may change the range of available gears by
simply tap-shifting the plus/minus button up or down. The 6-speed’s Tow /Haul mode reduces excessive shifting
when towing or hauling a heavy load, and it automatically engages grade braking. Grade braking assists in
maintaining desired speeds on downhill grades by implementing a shift schedule that utilizes the engine and
transmission to slow the vehicle. Available heavy-duty cooling helps deliver improved trailer ratings on all models
equipped with the 5.3L V-8 engines and the 6-speed transmission. Standard with the 4.3L V-6 and 4.8L V-8 is an
electronically controlled 4-speed automatic that features overdrive for highway driving and automatic Tow / Haul mode.

Sierra 1500 capitalizes on a
wide front track and a boxed
frame with high torsional rigidity.
Torsional rigidity—resistance to
twisting—contributes to dura-
bility and to performance. By
hydroforming the front rails, our
engineers eliminated several
welds, allowing for tighter pack-
aging and improved fit at bolting
points. The rear rails are fully
boxed all the way back to the
spare tire cross-member, where
they become C-Channel. This
sophisticated design helps boost
payload capacity without signifi-
cantly increasing vehicle weight.
Ingenious hydraulic body mounts,
standard on select models, securely
link the cab to the frame, but in
a way that isolates occupants from
road (or off-road) noise and vibration.

Front suspension is a coil-over-
shock design that has less mass
than the typical torsion-bar system.
Reducing mass improves ride
quality and handling everywhere
from rough roads to smooth high-
ways. The rear leaf-spring design
combines a smooth ride with out-
standing load-carrying capability.

For confident stopping in a wide
variety of conditions, a four-wheel
Antilock Brake System (ABS) is
standard. Rack-and-pinion steer-
ing provides precise performance
and an on-center feel. It also
offers low-speed assist for easier
maneuvering in tight spots.The
result is confident handling,
remarkable payload capabilities1
and smooth, quiet performance
on the highway.

The StabiliTrak stability control system and traction control are standard
on all 1500 models and select 2500HD models. The system has sensors
that read the position of your steering wheel, vehicle speed, brake pressure,
lateral acceleration and turning rate, then feed the data to an onboard
computer. If your Sierra is not responding adequately to your steering input,
the computer adjusts engine speed and applies brake pressure to any
individual wheel to help keep you on track. Its rollover-avoidance feature
can help mitigate roll forces. Its sensors are programmed to proactively
predict and help counteract vehicle “tip-up” on a flat road surface.

Sierra heavy- duty pickups offer the power and performance GMC is famous for— on a larger scale. With an
extraordinary 660 lb-ft of torque, the optional Duramax Diesel 6.6L V-8 Turbo engine makes the 3500HD the most
powerful V-8 one-ton.
2It also features a GCWR of up to 23,500 lbs.3
The Duramax V-8 is paired with the Allison 1000 6-speed automatic transmission (shown at right). It allows
you to activate Tow/ Haul mode simply by pressing a button at the end of the shift lever. In addition to grade
braking, the Allison 1000 adds cruise braking. If you’ve set the cruise control, it detects when you’re accelerating
downhill and automatically downshifts. And with tap-shifting, you can manually select upshifts and downshifts.
And every GMC heavy-duty truck is backed by the best coverage in America, including GMC’s 5-Year/ 100,000-
Mile Transferable Powertrain Limited Warranty,

A robust recirculating-ball steer-
ing system features a cast-iron
housing. With precise engineer-
ing, the system provides you with
an enhanced on-center feel and
a greater feeling of control. To
accommodate the greater loads,
Sierra HD models are equipped
with disc brakes front and rear.
The front frame section is
hydroformed to increase struc-
tural rigidity by producing more
consistent steel-wall thickness.
The mid-frame section uses a
lipped C-section, which is roll-
formed and draw-bent during
the manufacturing process for
maximum strength.
The renowned ability of the Sierra
HD models to combine sheer
capability with poise on the road,
and admirable comfort for their
occupants, rests on a frame
that incorporates the full range
of contemporary heavy-duty
chassis design.

Front independent suspension
with torsion bars allows high
gross vehicle weight ratings and
superb load-carrying capability.
It also helps produce a smooth
and comfortable ride. In the
rear, semi-elliptical multileaf
springs (two-stage on 2500HD,
three-stage on 3500HD) and gas-
charged shock absorbers help
produce a smooth ride under
loaded and unloaded conditions.
The legendary Z71 Off-Road

MAX Trailering Package (page 28).
For the really big numbers, you
want Sierra 2500HD or 3500HD
capability. On all Sierra models,
the available trailer brake con-
troller is completely integrated
with the vehicle’s electrical
and ABS systems, allowing
your trailer’s brakes to operate
simultaneously with the vehicle’s
brakes. The brake controller
switch is
conveniently
located on the
lower left part
of the instru-
ment panel.
rearview camera system
An available Rearview Camera
System features a built-in camera
mounted on the tailgate. When
you shift into reverse, an image
from the camera is displayed in
a portion of the rearview mirror
(so you can still see other objects
in the mirror). Just the thing for
backing up to a trailer. The mirror
reverts to a normal full-frame re-
flection when you shift into drive or
park.The available Touch-Screen-
Navigation3System includes a
rearview system that transmits the
image to the NAV screen.
1Maximum trailer weight ratings are calculated assuming a base vehicle, except for any option(s) necessary to achieve the
rating, plus driver. The weight of other optional equipment, passengers and cargo will reduce the maximum trailer weight your
vehicle can tow. See your GMC dealer for additional details. 2Requires MAX Trailering Package (includes Vortec 6.2L V-8).
3Map coverage for Puerto Rico and the Virgin Islands available on separate disc. Coverage not available for portions of Canada.
