Going hybrid makes Chevrolet Tahoe 2Mode a treat.

General Motors plans to start selling gasoline-electric hybrid versions of its full-size Chevrolet Tahoe and GMC Yukon SUVs this fall, hoping their improved fuel economy will attract mileage-minded buyers back to the potentially profitable big SUV market. The hybrids will come only well-equipped. But GM says they won't be the most expensive in the $35,000-to-$55,000 Tahoe/Yukon line. A few hours in a preproduction Tahoe hybrid around Northern Virginia, in traffic and on highways, was satisfying.
