TrueDelta Reviews the Real Gas Mileage of the Lexus RX

Lexus RX Real Gas Mileage: Pros
YearComment
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
