Originally, GM had
proposed using a mild hybrid system, such as on the Vue
hybrid, for the GMC Yukon hybrid. Fortunately, GM is now developing the Yukon
hybrid as a full hybrid using its new dual mode hybrid
technology.
According to the most recent reports, the
Yukon hybrid will be available in the later half of 2007
as a 2008 model.

In May,
GM showed off a Tahoe
hybrid for some reporters - which will be very
similar to the Yukon hybrid in terms of the hybrid
powertrain - so the vehicle is near production.
Nonetheless, according to GM at that time, the company's dual mode
hybrid Tahoe (and Yukon) is still in "development
stages".
GM's
two-mode hybrid technology will place electric motors
mounted inside the transmission to assist a
300-horsepower V-8. So, the hybrid Yukon should have the
power most large SUV consumers need.
Another
benefit of GM's dual mode powertrain will offer the hybrid
Yukon the ability to lock
the electric motors out of the drive train when extreme
engine power is needed, such as when towing. This
capability will enable the Yukon hybrid to tow up to 6,000
pounds - something Toyota hybrids cannot do at this
point in time.
And why
the heck are you getting a Yukon for if you aren't going
to pull something heavy?
In terms
of the dual mode hybrid drive, essentially, one drive
mode will assist with slow, city driving, the other with
highway driving. This helps GM hybrids achieve optimal
fuel efficiency based upon driving conditions and could
make GM's hybrids superior to Toyota's single-mode
hybrids in some driving conditions, particularly highway
driving.
In
addition, the hybrid Yukon will be 300 pounds lighter
due to the use of aluminum in the hood and front
tailgates - another tool to increase fuel economy.
Overall,
the two-mode hybrid system should make the Yukon hybrid
25% more fuel efficient in combined city/highway
driving.
There is
no final word on pricing for the 2008 Yukon hybrid, but
early reports indicate it will probably resemble the way
that Lexus prices the RX400h
versus the standard RX - a difference of some $10,000.
Thus, the
Yukon hybrid might not be cheap.
I was able
to view the Yukon hybrid at the 2006 Los Angeles Auto
Show. For Yukon fans, the Yukon hybrid should be a
winner.
