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
