2007 GMC Yukon: Still Too Much?
I realize I may be stepping on some toes, but please hear me out. The upcoming, new from the ground up, GMC Yukon is certain to be perceived by some as being too much…in size, that is. With fuel prices at an all time high and consumer sentiment shifting to smaller vehicles will the GMC Yukon be considered outdated even before it hits showroom floors in Spring 2006? Let’s take a look at many of the changes planned for the all new Yukon and then you can decide for yourself.
General Motors has been itching to release the Yukon and a host of other full sized GMC/Chevrolet models to the public as soon as possible. Some find this odd, particularly since fuel prices are high and demand for large vehicles is on the decline. Still, there is good reason why GM wants you to take a closer look at upcoming offerings including the 2007 GMC Yukon, their big SUV:
New from the ground up. Ask anyone who purchases large trucks and SUVs and they will tell you that owning one with the latest technology is often a deciding factor in purchasing a new model. GM is right on schedule with the update; however as with any “older model” vehicle currently on the market sales typically decline as a new model is prepared for release.
Engine efficiency. The 2007 Yukon’s two V8s will produce greater horsepower than the previous engines, but they will register an increase in fuel economy. How so? General Motors is incorporating Displacement on Demand technology, which deactivates some of the cylinders at low loads for increased fuel economy. You may recall a more basic version of this technology being applied to Cadillac models in the early 1980s; that particular V8-6-4 technology was ahead of its time and GM had to pull it back then as the engines did not do what was intended for them to do. Now, more than a generation later, General Motors has worked out all the kinks and has vastly improved on the original idea.
Safety. Roof mounted side curtain air bags will now be made available for all three rows of passengers. GM has been on a major offensive over the past half decade or more in stressing safety, a big seller for any vehicle. A better ABS system and StabiliTrak, GM’s premier handling system, will also be included.
Technological improvements. Rear camera systems, power fold and tumble rear seats, and an improved navigation system are some of the updates. The interior of the 2007 Yukon is actually larger than preceding models.
While General Motors can only wish that fuel prices were lower, the company is hoping that each of their new models can take a greater slice of the shrinking big truck/SUV pie. With new models from Ford still a year or two away, the Yukon is poised to cut into Expedition sales as well as take back sales lost to Lexus. Even with high fuel prices in place, there will likely always be a core market of people who need a vehicle of the Yukon’s size; General Motors knows this and has updated their line of vehicles to keep pace.

A standard Vortec 5300 5.3-liter V8 engine powers the Sierra Hybrid and a 4-speed Hydra-Matic automatic transmission coupled with the full-size truck segment’s first hybrid propulsion technology for improved fuel economy.
The Sierra hybrid uses electric power even less frequently. Its gasoline engine can shut down when the car is stopped (actually, when it's braking to a stop, below 13 mph or so) and-that's it. The batteries (three 14-volt units plus the standard 12-volt) cannot power the truck at low speeds. Nor do they help out the gasoline engine, which therefore can't be any smaller. It's the same 5.3-liter V-8 GM pickup buyers know and love. Because of the limited nature of this hybrid system, the benefits are mild: roughly 2 mpg in city driving and 1 mpg during the EPA's highway cycle.
The system replaces the traditional starter motor and alternator with a compact 14-kw electric induction motor or starter generator integrated between the engine and transmission. The starter generator provides fast, quiet starting power and allows the gasoline engine to automatically start and stop under certain conditions to conserve fuel.
The Sierra Hybrid also offers four 120-volt/20-amp electrical auxiliary power outlets located under the rear seat and in the pickup bed. Because the 5.3-liter V-8 is the same as that in non-hybrid pickups, its power and torque outputs are the same (295 horsepower, 325 pound-feet of torque). Acceleration, towing, and payload are undiminished. The extra hybrid gear takes up very little space-the biggest component, the three extra batteries, is under the rear seat. One interesting feature of the hybrid trucks are its four, 120-volt 20-amp AC power outlets in the cargo bed and the rear seat; but the engine must be running in order to use them.
As in hybrid cars, the gas engine shuts off at stoplights to save fuel, and an electric motor restarts the engine when the gas pedal is pushed. Unlike most hybrids, the electric motor does not help propel the vehicle. The system does include a unique feature aimed at commercial users and picnic tailgaters: a generator that provides 120-volt power for running electrical accessories.
Available in California, Washington, Oregon, Alaska, Nevada and Florida, the Sierra Hybrid delivers up to 10 percent better fuel economy with the same power and performance as the 5.3-liter V8. In fact, that same engine powers the Hybrid, developing the same 295 horsepower and 335 pound-feet of torque.
GM is not to be outpaced in this hurried race for the development of producing fuel cells. With all these amazing technological breakthroughs in the automotive industry, Partstrain stands by its commitment of delivering excellently engineered GM performance parts, replacement auto parts to go with GM's efforts of sustained production of environment friendly vehicles.
