The Saturn Vue Green Line, due out later this summer, has received an EPA rating of 32 miles per gallon, the highest highway rating ever for an SUV, according to Automobile
. In line with its mild hybrid technology, consisting of an integrated belt-driven starter-alternator, the highway efficiency is excellent, but its city driving efficiency of 27 mpg is lower than the comparable Ford Escape Hybrid, which is rated at 36 mpg in the city. The improved highway efficiency for the Vue can be attributed improved aerodynamics and an ECU that allows for fuel shut off on deceleration. Where the Vue Green Line really shines is the price department, undercutting the Ford Escape Hybrid by $4,000. Instead of a shift light street racers crave, the eco crowd gets an "eco" light in the Vue, warning the driver when the current fuel economy is higher than average.
