What Our Members Are Saying about the Real Gas Mileage of the 2006 Lexus IS

2006 Lexus IS Real Gas Mileage: Pros
YearBody/PowertrainComment
2006 4dr Sedan 204-horsepower 2.5L V6
6-speed shiftable automatic RWD		 At around 200hp, it isnt the fastest luxury sedan. However, on my roadtrip across the eastern / mid eastern USA I was able to get ~33 ish mpg (computer reported) on flat terrain and premium fuel. City mpg is what I expect,22-25ish. But I think it is great as a long distance comfortable vehicle. see full Lexus IS review
