Tahoe, Yukon hybrids ready by end of year?

Tahoe and Yukon hybrids still in development stages

GM was able to show off working versions of both the Tahoe hybrid and the Yukon hybrid yesterday, according to the DetroitNews, but neither hybrid is yet production-ready.

"We're still in the development stages, but we're on track to have these vehicles ready by the fourth quarter of this year," said Larry Nitz, GM's executive director of hybrid technology.

GM's first two full hybrid vehicles, utilizing GM's dual mode hybrid powertrain, are expected to offer a 25 percent increase in fuel economy.
