I am in the greater Los Angeles area too. We get 31 to 36 MPG so far. Since we are driving pretty fast and not for economy, my guess is that there is a problem. My wife cruises up the Conejo grade at 77 MPH and rapid starts too. This is in a 2008 451 with a thousand miles.

i live in sun city and my last three mpgs were 36, 42 and 40mpg. i don't drive much, but i have about equal town and highway driving. it is real hard to stay at 70 so my run to san diego ends up at 75+ even on the hills. i've been told if i go 55 - 65mpg my mileage would be better and it would be good for the enviornment. a horror thot is going 55mph on i-15. you should take your car to another smart certified dealer. it may be covered under the warranty, but ask first. 21mpg is a problem. i register my fuel purchases at www.fueleconomy.com and their are several smarts listed so you can see mpg they get - some more and less than me. good luck.

good point about needing to use premium, not doing so can kill your mileage, also running the air conditioner will drop your mpg, doing both is a killer and jack rabbit starts and cruising at over 70 mph will also do you in - but all that being said, I have never seen anyone get mpg that bad, you should have it checked. I just drove fom Albany, NY to Phippsburg, Me. and was doing 70 to 75 with the air on and I still was getting 42 mpg

I live in Miami, a very flat place. I drive normally, in automatic, Its a hot summer and the AC is on all the time. I do mostly city driving. The car a 2009 passon has 1600 miles, and I have gotten 26 MPG. I have not had it back to the dealer, but the Mpg is so far below what I should get, I'm getting ready to take it in.

My overall average after 6900 miles is 38.4 mpg. Much of this is freeway driving between 65 and 75 mph and about half is with the top all the way down on my cabriolet. Open windows do lower the mpg but only by a few mpg. The a/c does impact milage a lot but it still seems to be above 30 mpg. I would also recommend premium if that's not what your using. I also have do deal with some serious cross winds and headwinds on the Eastern shores of Lake Michigan.

I'm about to take my SMART Passion in to the dealer as well. When I first got the car I was driving some highway miles and was getting 36 mpg. I'm mostly driving in town these days and my last 3 tanks got 26 mpg. I only have 3500 miles on the car. I tell everyone who asks me about the car...and there are many of those....I'm dissapointed in the gas mileage. They all agree I need to take it in and have it checked. I use premium gas so that is not what's going on. The Mini owners are laughing at me!
