Engine
Here’s high-tech proof that a full-size SUV can offer outstanding performance—and remarkable fuel economy. Available Gen IV Vortec 5300 V8 models feature a technological advancement called Active Fuel Management. In normal driving conditions, Active Fuel Management deactivates four of the V8’s cylinders when less power is needed—essentially turning the V8 into a V4. When you need V8 power, it’s automatically there for you. The engine always starts and idles on eight cylinders, and runs on eight during brisk acceleration or when carrying or towing loads. What’s more, it switches between V4 and V8 operation so seamlessly that you’ll never notice the transition. In testing, the new system increased fuel efficiency by up to six percent.
Braking system
Four-wheel disc brakes complemented by an all-new Bosch® antilock braking system and larger, vented rotors provide even greater stopping power, with an enlarged cooling area for improved performance.
Power fold-and-tumble second-row seats
Welcome to a new era in convenience. Second-row seats feature a new power fold-and-tumble design—an industry exclusive. Two buttons in the overhead console allow you to fold and tumble the left or right seat individually. Or you may simply push a button located on either rear-door pillar and each seat is automatically unlatched, folded and tumbled for easier access to the third-row seat. You may then manually return them to their original position.
StabiliTrakTM Stability Control System
StabiliTrakTM, standard on Yukon XL 1/2-ton models, is an engineering advance that improves safety, stability and control on all road surfaces—and it’s especially valuable during emergency maneuvers. Sensors 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 Yukon XL is not responding adequately to your steering input, the computer instantly adjusts engine speed and brake pressure to any individual wheel to help keep you on track. Rollover mitigation capabilities are also provided, with the sensors programmed to proactively predict and help counteract vehicle “tip-up” on a flat road surface.
A SUPERB COMBINATION OF POWER AND FUEL EFFICIENCY
The 2012 GMC Yukon XL exploits the latest automotive technology to create a full-size SUV with exceptional capabilities. The Yukon XL is born from the work of engineers who do not wait for ideas to come to them, but who instead actively seek them out and apply them. Advanced engineering ensures power and performance combined with exceptional fuel efficiency. Chassis and suspension systems provide agile handling matched by a remarkably smooth ride. Refined interiors are both comfortable and spacious. Looking beyond the drawing board is just one more way we engineer to the highest standard.
