2. Lexus RX450h 30/28/29
The popular Lexus RX crossover should be known by now as the most fuel efficient crossover. But even when equipped with AWD it gets pretty impressive numbers, which put it just below our number one most efficient AWD vehicle. The AWD-equipped RX450h features the latest version of Toyota’s Hybrid Synergy drive system, which has three electric motors. Pair those three electric motors with a 3.5-liter V6 engine, and the RX450h packs a total of 295-hp. The total package means that the big Lexus can still get a combined 29 mpg, an impressive 30 mpg in the city and 28 mpg on the highway. Of course, this fuel efficiency isn’t cheap, as the Lexus still costs $47,310 and requires premium fuel.
