Although the 2009 GMC Yukon Hybrid is a carryover model from the previous year, critics and consumers are still talking about its innovative features. The full-size SUV seats up to eight passengers and includes a 60/40 split folding second row and 50/50 split bench for the third row. This interior adaptability gives the Yukon Hybrid enough cargo room to be comparable to the hauling capacity of a full-size pickup.

With all that space, GMC fitted the Yukon Hybrid with a Vortec 6.0L SFI V8 LIVC that generates up to 332 horsepower. The hybrid engine is equipped with Active Fuel Management. This feature allows the Yukon to run on eight or four cylinders, whichever is necessary at a particular driving time. By only running on four cylinders during slower, less demanding driving, the Yukon Hybrid saves a significant amount of gasoline. A four-speed automatic transmission is standard, and no other options transmission options are available. The four-wheel anti-lock brakes include a regenerative braking feature that repowers the Yukon's battery every time the pedal is pressed. This allows the model to create its own energy; thus, the SUV is able to save even more fuel.

While the hybrid additions are environmentally friendly, they do not particularly make the Yukon comparable to other hybrids on the market. With only 21 city MPG and 22 highway MPG, the hybrid edition is not much better than its gasoline-powered brother. Nevertheless, GMC is making headway with the development of an even more advanced hybrid system to utilize in future Yukon models.

Inside, buyers will get a wealth of additions like tri-zone automatic climate control, power programmable door locks, one-year subscription to OnStar, and five auxiliary power outlets. These outlets are located throughout the model, allowing for access from several different locations. Optional features range from a rear seat DVD system with infrared headphones and audio/video input jacks to an electric tilting sunroof.

Overall, the 2009 GMC Yukon Hybrid is making an impression on the SUV market, but without a significant increase in the fuel economy, buyers will not stay interested for long. Base priced at around $50,920, the Yukon Hybrid will be out of many consumers' price ranges; however, those that are looking for a full-size SUV that is completely loaded and makes a bit less of a dent in the environment will discover that the Yukon is an acceptable match.
