In what just seems to be a move to bolster its hybrid portfolio, GM is unveiling the 2009 GMC Yukon Denali Hybrid at the 2009 New York auto show.

Like the recently announced Cadillac Escalade Platinum Hybrid, the Yukon Denali Hybrid takes the 2-Mode hybrid system offered in the base Yukon model, but applies it to the brand's top-tier SUV offering. As is the case with "normal" Yukon and Yukon Denali models, the Denali Hybrid adds features (e.g. a custom grille, 22-inch wheels, upscale interior trim) that aren't offered on the Yukon Hybrid.

The 332-hp, 6.0-liter V-8 underhood, however, is identical to those used in GM's other full-size hybrid trucks. So too is the 2-mode hybrid transmission, which switches between an infinitely variable mixture of gasoline and electric power to fixed gearing when needed. GM says the system allows the Yukon Denali Hybrid to achieve 21/22 mpg city/highway with rear-wheel-drive.

GM expects Yukon Denali Hybrids to arrive at GMC dealers in May. Two-wheel-drive models will start at $59,185, while four-wheel-drive carry a base price of $62,030.
