Is the Ford Escape hybrid really the "most fuel efficient SUV"?

I just saw a video that included an ad that claims the 2008 Ford Escape hybrid was "the most fuel efficient SUV on Earth." Ford has said this for years and, for years, Ford was right. This is not quite so true for the 2008 model year, though. Technically, Ford is still the most fuel efficient in 2008 but two other SUVs are just as fuel efficient; the Mazda Tribute hybrid and Mercury Mariner Hybrid. This raises an interesting question; Is Ford really "the most fuel efficient" if two other SUVs are just as fuel efficient? Tell me what you think in comments.

Update: Thanks to everyone that pointed out the Ford Escape, Mazda Tribute and Mercury Mariner hybrids are just rebadged versions of the same vehicle.
