POWERTRAIN
Terrain offers two engine choices. The standard engine is the 2.4L I-4 with 32 EPA-estimated highway mpg, or there’s the available 3.6L V-6 that offers
the most horsepower in its class, 301 hp with 24 mpg hwy.

It’s efficiency that comes from engineering innovations like Variable Valve Timing (VVT)
and direct injection to make the most power and torque from every drop of fuel.

VARIABLE VALVE TIMING
(VVT) Standard in both Terrain
engines, this technology gives
you the power of a high-
performance engine with the
low-speed response you need
for situations such as trailering
or climbing steep inclines. VVT
constantly monitors and changes
how the valves open and close
to give you optimum levels of
torque across the entire range of
engine speeds.
22
DIRECT INJECTION For precise
fuel distribution and fast, efficient
combustion, both Terrain engines
feature direct injection technology.
Simply put, this system moves
the fuel closer to the point where
it ignites inside the engine—in the
combustion chamber. By injecting
fuel at over 2000 psi, the air and
fuel mix more completely. This
helps the charge burn fast for
crisp throttle response and lean
for efficiency at cruise speeds.
The result: The 2.4L I-4 Terrain with
automatic transmission features
32 hwy mpg,
2
and 3.6L V-6 models
offer more power and an EPA-
estimated 24 highway mpg.

FUEL-SAVING MODE To help you
save fuel, the 2.4L I-4 engine has
an Eco-Mode button that, when
pressed, delivers slightly better
fuel economy by holding gears
longer, with only a slight decrease
in acceleration.
E85 FLEXFUEL CAPABILITY
3
To give you more choices at the
pump, both Terrain engines can be
equipped to use E85 ethanol fuel.
This advanced biofuel is a mixture
of 85 percent ethanol, a mostly
renewable fuel that helps to reduce
the need for imported oil, and 15
percent unleaded regular gasoline.

6-SPEED AUTOMATIC WITH
OVERDRIVE For brisk acceleration
from a stop and reduced highway
rpm, this advanced transmission
has a wide ratio spread. That
means first gear is numerically
“high” to let the engine rev quickly
into its power band, while fifth
and sixth gears are overdrive
ratios that are numerically “low”
to reduce engine rpm, saving fuel,
reducing wear and minimizing
engine noise. The gear ratios
between low and high are evenly
spaced for strong, consistent
acceleration at almost any speed.
AUTOMATIC GRADE BRAKING
To prevent unwanted acceleration
and reduce the need for the driver
to brake during a hill descent, the
6-speed automatic with overdrive
features Automatic Grade
Braking. This “smart” feature
monitors braking, acceleration,
throttle position and even
whether a trailer is connected to
the vehicle. Then it commands
the transmission to remain in
a lower gear if the vehicle is
decelerating or coasting on a
downgrade to help you hold your
desired speed and minimize the
need for additional braking.
OIL LIFE MONITOR For long life
and durability, changing your
engine oil at the right time is
essential. GMC engineered the
mystery out of this essential
service with the Oil Life Monitor.
It calculates how much life your
oil has left, based on when and
how you drive. Then it updates
you with a telltale on your Driver
Information Center.
