Cost: $55,585
Fuel economy (CR test): 19 mpg
Total 5-year savings: $3,700
It might seem odd that a vehicle that gets 19 miles per gallon would save buyers more money the Toyota Prius, which gets 44 mpg but is further down the list.
But you have to assume that the alternative, for a Tahoe Hybrid buyer, would be a non-hybrid Tahoe, which gets just 14 mpg, according to Consumer Reports' testing.
For those who need the towing and hauling capability of a large SUV - needs that can't be met by a small car - that 5 mpg difference in the Tahoe Hybrid adds up to $4,500 in fuel savings alone over five years, according to Consumer Reports. Plus the Tahoe Hybrid qualifies for a $2,200 federal tax rebate.
