Greg Morrison: What is this GMC Yukon have in common with this Dodge Durango, obviously both are full size SUV's, which were about as popular as an IRS audit these days. The Yukon it's Cadillac cousin the Escalade and the Chevy Tahoe also share something else with the Durango. They are all available now as Hybrids designed to be cleaner and more fuel efficient than traditional gasoline only versions.
At the heart of these two vehicles there is a two mode transmission that switches between electric and gasoline operation depending on speed and driving conditions. This gear box was developed jointly between GM and Chrysler as their answer to the Durango for a hybrid technology.
The Yukon version only comes with a 6 liter V8 engine and a 6 Speed automatic transmission with the selectable two or four wheel drive capability. General Motors probably tout it's fuel economy numbers which are some what better than the smaller engines and the regular gasoline powered versions. But reaching these numbers in daily urban driving requires a driver keep a close eye on a gauge, which measures whether kilowatts or gasoline are powering the truck. It should also be noted this engine uses GM's active fuel management system to improve economy.
In week of Atlanta traffic we were left wondering why the hybrid technology wasn't apply to a smaller engine like the 5.3 or 4.8 liter V8. While they may not be able to tow the 6200 pounds the hybrid can pull. Let's face it, there isn't that much demand to pull heavy boats or trailers these days. Ironically this technology comes and what maybe the end of the era for a large SUV's and at a time when the publics desire is already shifted to 8 passenger units, that could get at least 24 miles to the gallon in city driving. This is Greg Morrison.
