FEATURES & BENEFITS | 14

DEACTIVATING HYDRAULIC

VALVE LIFTER

VALVE

ACTIVE FUEL MANAGEMENT (AFM) For

maximum fuel efficiency when your load is light, and

maximum V-8 power when it isn’t, AFM senses load

and demand then seamlessly activates or deactivates

four of the engine’s eight cylinders, using specially

designed hydraulic valve lifters. It’s innovative

technology that results in better fuel economy

than any competitor.

EPA-estimated 15 city/21 hwy with the 5.3L V-8 engine. Based on

2013 GM Large Utility segment.

E85 FLEXFUEL CAPABILITY

For more choices at

the pump, Yukon’s 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 reduce vehicle emissions, as well

as the need for fossil fuels.

E85 FlexFuel capability is not available in AZ, CA, CT, DE, MA, MD,

ME, NJ, NY, OR, PA, RI, VT and WA. E85 is a combination of 85%

ethanol and 15% gasoline. Go to afdc.energy.gov/afdc/fuels/ to

see if there is an E85 fuel station near you.

6-SPEED AUTOMATIC OVERDRIVE

TRANSMISSION Engineered for control and

confidence in a wide variety of situations, the

6-speed automatic is standard on all Yukon models.

It’s an ideal partner for Vortec power. Loaded with

innovative technology, this transmission can help

you bring steep climbs, long grades and heavy

loads down to size.

POWERFUL COMBINATION. Yukon’s Vortec V-8 VVT engines offer uncompromising power, torque and efficiency. The 5.3L V-8 is tuned to deliver

power across a wide rpm range, while the 6.2L V-8 on Denali provides the most horsepower and torque in a full-size SUV. Active Fuel Management, included on both

engines, allows Yukon to offer outstanding performance and class-leading fuel economy.

Both engines are mated to a 6-speed electronic shifting transmission

designed to intelligently transfer power to the road.

AUTOMATIC GRADE BRAKING Standard with

6-speed automatic transmissions, Grade Braking

automatically senses when you want to slow your

Yukon, and when conditions are met, engages a shift

schedule that helps maintain your desired speed.

TOW/HAUL MODE This feature changes trans-

mission points to reduce shifting while trailering

or driving up or down hills.

DRIVER SHIFT CONTROL Standard on all models, it

lets you manually move through gear ranges. Move

the shift lever to “M,” and you get fingertip “tap up/

down” control of transmission gear range selection.

VARIABLE VALVE TIMING (VVT) Giving you

maximum power over the widest range of engine

speeds, VVT changes the engine’s performance

profile to match the driving situation. In the city,

VVT gives you a smooth idle and quick response

at low speeds. On the highway, VVT changes your

engine to a bold, high-performance V-8 with

horsepower to spare.
