I saw that someone recommended the Honda Pilot. I also have a Pilot and I love it, BUT it is certainly not as gas efficient as some cars and not even close to the Prius. Ford Escape is a hybrid SUV that is getting very good reviews. Where I work has bought 5 of them so far and been quite pleased. They also have several Prius and, trust me, two adults and two carseats would fill that car completely (read sardines!).
I also read that the Tahoe will have a hybrid next year, but I would never recommend buying a vehicle on it's first year out. Too many bugs to work out.
The Toyota Highlander also may come in the hybrid. Toyota advertised several years ago that it would be a hybrid the next year and then that didn't happen, but they may have gotten there now.
Go to Vehix.com . . . they are the best place I have found to study the vehicles and read reviews and compare.
Good Luck!
