As the original hybrid SUV, the Lexus RX 450h has long been the go-to vehicle for luxury SUV shoppers concerned about fuel economy. The smooth 295-hp V-6-powertrain delivers an estimated 28 mpg in the city and 32 mpg on the highway. In comparison, the non-hybrid RX 350 offers 18 mpg city and 25 mpg highway.

With an estimated 20 mpg in the city and 27 mpg on the highway, the Audi Q5 is one of the most efficient non-hybrid luxury SUVs for the year. True to the Audi nameplate, the vehicle delivers a sleek, rounded exterior design, sporty engine performance and a well-crafted interior. Among the compact SUV class, the Q5's 211-horsepower base engine isn't quite as power as alternatives. However, a 270-hp V-6 engine is also available (18 mpg city and 23 mpg highway) for those who want extra power. One downside of the Q5 may be price. Starting at $35,200, this is one of the more expensive compact luxury SUVs available for the year.
