This new Sierra HD has an available 6.6L
Duramax Diesel engine. Our engineers have
evolved this proven powerhouse engine
to offer more power and torque. It's quieter,
cleaner and B20 biodiesel compatible.
And,with an approximately 36-gallon tank,
it has a highway range of up to 680 miles.

It’s engineered to crush heavy-duty jobs. Drop a big payload into its bed and its
improved suspension will push right back up. Its maximum payload capacity
is now a substantial 6335 lbs1and is a 20 percent increase over our comparable
2010 models. Its maximum Front Gross Axle Weight Rating of 6000 lbs2is an
impressive 25 percent increase with the optional Snow Plow Prep. These numbers
are built on a powerful foundation. Sierra HDs have an all-new chassis design,
including a high-strength, fully boxed steel frame, an increased wheelbase, a
wider track and hydraulic body mounts under the cabins of the Extended Cab
and Crew Cab models to improve ride comfort. newton’S LawSof motion
“IF I HAVE SEEN FURTHER,IT IS BY STANDING ON THE SHOULDERS OF GIANTS.”
SIR ISAAC NEWTON 1643-1727
In 1687, Newton wrote his three Laws of Motion.And we admit
we may have bent, stretched and reinterpreted them a little.
But look at the result: a tougher, stronger, smarter Sierra Heavy
Duty. Of course, this is a GMC and the apple doesn’t fall far
from the tree. There’s a law Newton can relate to.
36-gallon fuel tanK
Our engineers increased tank capacity
to hold approximately 36 gallons of fuel
on all models. This significantly increases
the time between fill-ups. Just how much
time? You’ll have to ask Newton.

GMC engineers are specialists in making the big challenges seem
small. This time, we’ve made trailering heavy loads up and down
steep gradients far less stressful, with many braking and control
innovations. Sierra HD can help make trailering a full load from
Denverto Grand Junction (abeautiful 4-hour drivethrough the
Rockies) a lot less hairy. It also has an impressive 20,000 lbs
maximum fifth-wheel trailering capacity.

On single rear-wheel models, this new
