My real world economy has been 33 mpg hwy (not the computer figure, an optimistic 34.5-35)which is better than expected and slightly over 20 in city driving (not heavy traffic), also better than expected see full Lexus IS review
2008 Lexus IS Real Gas Mileage: Cons

2009 4dr Sedan 204-horsepower 2.5L V6
6-speed shiftable automatic RWD
Wish it got better fuel economy for such a small car and engine... Sticker is 21/29, I'm averaging 27MPG (computer read); avg on hwy is about 33-34 mpg while city is about 19-23mpg. Engine variety would help, a 4 cyl + turbo or something, but toyota/lexus isn't exactly known for that. see full Lexus IS review
