TrueDelta Reviews the Real Gas Mileage of the Lexus RX

Lexus RX Real Gas Mileage: Pros
Year	Comment
2013	The new transmission doesn't affect EPA city mpg, which remains a competitive if not outstanding 18. Highway mpg receives a bump from 24 to 26, putting it two to three mpg over most competitors. At a steady 75 mph, the F Sport engine is spinning 1,950 rpm, vs. 2,300 in the regular RX with a six-speed automatic. In suburban driving with the engine warmed up the trip computer typically reported 22 mpg. A very light foot bumped this by three mpg, while a heavy one sunk it by about the same. Buyers who put a high priority on fuel economy will prefer the RX 400h hybrid. It earns EPA ratings of 32 city, 28 highway, and is even a little quicker than the RX 350. Real-world suburban mpg appears to be about 29. see full Lexus RX review

2010	4dr SUV 245-horsepower 3.5L V6 Hybrid 6-speed shiftable CVT AWD	I drive about 10% traffic, 30% city, 20% suburban and 40% highway (75-80 mph). My driving is quite smooth. Fuel consumption is 28 MPG see full Lexus RX review
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 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

2006	4dr SUV 208-horsepower 3.3L V6 Hybrid CVT AWD	I researched this a fair bit. I did not want an SUV but the space offered, reliability, and fuel economy sold me. I regularly get 26-27 MPG city/hwy combined, way better then any other SUV (Highlander excepted) see full Lexus RX review

2013	4dr Sedan 256-horsepower 3.6L H6 5-speed shiftable automatic AWD	The downside of the H6 is not great gas mileage, but for what you are getting, it is not bad. On the highway with cruise control have managed to get about 30 mpg. In a mix of city and highway it gets 23 mpg. In city only it gets 18 mpg. Again, for AWD not bad, but not great. Want better gas mileage, get the H4 engine. see full Subaru Legacy review

2010	4dr Sedan 170-horsepower 2.5L H4 6-speed manual AWD	A bit thirstier than I had hoped - but the AWD probably has a lot to do with that. see full Subaru Legacy review
2009	4dr Sedan 170-horsepower 2.5L H4 4-speed shiftable automatic AWD	The fuel economy with a 4 cylinder 170 hp engine is pretty disappointing at 22-23 mpg. The AWD system is responsible for some of the loss but I also drive an AWD Acura TL SH-AWD with a 6 cylinder 305 hp engine that is only marginally worse at 18-19 mpg. see full Subaru Legacy review
2008	4dr Sedan 245-horsepower 3.0L H6 5-speed shiftable automatic AWD	I do not dislike the fuel econ, its AWD and I knew that going into the purchase, after you walk away from a totaled vehicle, safety becomes the prioroty over fuel econ. Have been able to get 32mpg out of both vehicles with smart driving see full Subaru Legacy review
