Audi S4 Avant
Least efficient small station wagon
EPA City/Highway: 13/20
No one combines all-wheel drive, performance, and refinement better than Audi. The Subaru WRX comes close, but can't beat the punch and wondrous sounds of the S4 Avant's 4.2 liter, 340 horsepower V-8.
Compact station wagons don't make sense as there's barely any more space than their sedan counterparts. No matter, though, just floor it and hang on to your Golden Retriever.(Audi AG)
