Any of the normal gasoline versions of the ML have a thirst for premium—even if you go with the basic V-6 ML350, it only gets 15 mpg city, 20 highway with all-wheel drive. But the new ML450 Hybrid combines the gas V-6 with two electric motors and a nickel-cadmium battery pack to provide good acceleration yet return fuel economy figures well into the 20s. They're even still rated to tow 5,000 pounds. Finally, you can't actually buy an ML Hybrid; they're lease-only, but lease prices have already been discounted substantially.
