General Motors has had a checkered relationship with hybrids in the last few years. Through the 1990s they did a lot of development work in the area, particularly through the federally funded Partnership for a New Generation of Vehicles (PNGV). Ultimately, Toyota and Honda were the first to actually bring hybrid electric drivetrains to market. GM eventually brought their first light duty hybrid system to market with the mild parallel hybrid that was offered on the Silverado and Sierra pickups for a couple of years. That was followed by the belt-alternator-starter system that debuted in late 2006 on the Saturn Vue. Neither of these systems could in any way be considered a commercial success although GM claims to have learned some real world lessons from them.
Late in 2007, GM finally launched production of the Chevy Tahoe and GMC Yukon hybrids, the company's first "strong" or full hybrid systems offered on light duty vehicles. The hybrid full-size SUVs have been controversial among hybrid fans who are of course dubious about why GM is bothering to apply this technology to these big, heavy vehicles. Even with the hybrid system, the rear wheel drive Tahoe still only manages an EPA combined rating of 21 mpg, less than half of the 46 mpg that a Prius gets. There is, however, a method to the apparent madness which we'll come back to. Previously we've had a couple of opportunities for short drives of the Tahoe hybrid at GM's Milford Proving Ground. Now that we've had a chance to live with it for a week you can read all about it after the jump.
