2008 Lexus RX Real Gas Mileage: Pros
YearBody/PowertrainComment
2009 4dr SUV 270-horsepower 3.5L V6
5-speed automatic AWD		 On flat ground with cruise control on it will get 29 mpg. I find that outstanding. 23-25 mpg is average. see full Lexus RX review
2008 4dr SUV 209-horsepower 3.3L V6 Hybrid
CVT FWD		 Like the fact that it is a hybrid and a "greener" choice for an SUV see full Lexus RX review
2008 4dr SUV 209-horsepower 3.3L V6 Hybrid
CVT FWD		 Averaging 26+ on highway, higher in city driving see full Lexus RX review
2008 4dr SUV 209-horsepower 3.3L V6 Hybrid
CVT AWD		 We compared the 2008 RX400h (discounted) vs the 2009 Nissan Murano. The gas savings by going with the Hybrid exceeded the difference between the two vehicles. see full Lexus RX review
2007 4dr SUV 208-horsepower 3.3L V6 Hybrid
CVT AWD		 Not quite as good as advertised but what I realistically expected see full Lexus RX review

2008 4dr SUV 270-horsepower 3.5L V6
