Luxury SUV - 2013 Lexus RX 450h
Gas mileage (city/highway; combined mpg): 32/28; 30
Efficiency-cost rating: 0.64
If you want a hybrid and a lush SUV, there are a few choices that serve that dual purpose well, but the Lexus RX 450h’s efficiency-cost rating outperforms the rest. Even with all-wheel drive, the RX 450h’s ECR of 0.60 outdoes the Volkswagen Touareg Hybrid at 0.33 and Porsche Cayenne Hybrid at 0.30, both of which come standard with all-wheel drive — and $60,000-plus price tags.
