You read the headline right. The full size SUV Chevy Tahoe and GMC Yukon, when equipped with the dual mode hybrid system, get better fuel economy than Camry. In fact the hybrid version of these vehicles delivers a 50% increase in fuel economy over their standard non-hybrid version. GM announced an EPA estimated 21 mpg city and 22 mpg highway for the 2 wheel drive hybrid Tahoe and
Yukon models. That matches Toyota Camry’s 4 cylinder model’s EPA estimated 21 mpg city and beats the 6 cylinder model by 2 mpg. All of this is possible without any compromise in power thanks to the world class dual mode hybrid technology. It is important to note that these estimates are using the EPA’s new more conservative “real world driving” ratings.
America has had a long love affair with the full size SUV. That relationship has been challenged by high fuel prices. Now you will be able to get the benefits of the full size Tahoe and Yukon with the mileage of a mid size sedan. Did I mention power? These hybrid family movers boast a 6.0 liter V8, delivering 332 horse power and 367 foot pounds of torque.
The dual mode hybrid system allows the Tahoe and Yukon to run up to 32 mph on electricity alone. After that speed, the trucks either run on gasoline alone, or a combination of gasoline and electricity. GM’s fuel management system will deactivate cylinders at highway speeds under low load increasing the fuel efficiency. What is really neat about this system is you don’t even know it is happening, and it operates flawlessly, unlike the old 2-4-8 system of the early 80’s.
GM is also planning to use the Two Mode system in its Silverado and Sierra pickups. I am certain as production capacity increases; you will see this system on many more GM vehicles. There is unconfirmed talk about it showing up on some of the mid sized luxury vehicles, but as close as I am to the GM brass, I could only get “I can neither confirm nor deny those rumors” out of my friends.
GM continues to invest heavily in alternative fuel technology. They offer the most E85 capable vehicles in the world that run on a fuel mixture of 85% ethanol, usually from corn, and 15% gasoline. The new Chevy Volt plug-in electric vehicle will run entirely on electricity, with gasoline only being used to run a generator when trips exceed 45 miles. GM also has a fleet of Hydrogen Powered Equinox SUV’s running America’s roads where the only emission is water vapor. I am working with GM to set up a demonstration running a hydrogen vehicle from Washington DC to Ocean City, demonstrating an emission free family vacation.
GM made its announcements about the fuel economy of the new Hybrids at the Texas State Fair. I cannot resist telling you this. Toyota brought its racing display and racing trailer. The racing trailer was towed to the fair not by Tundra, but by a one ton Chevy Silverado. I have pictures.
