Following on the heels of the eco-friendly Chevy Tahoe that debuted a few days ago comes it’s equally as green first cousin, the 2008 GMC Yukon Hybrid SUV. This brings the number of available hybrid sport utilities to eight, with a couple more expected later this year (Cadillac Escalade, 2nd generation Saturn Vue). The first of these new Tahoes that I was able to find online and at a local GMC dealer had sticker prices of about $60,000. With a price tag like that, I’m guessing many new owners will be leasing rather than buying these gentle giants.
