451 smart fortwo

I have driven the SMART Passion now for appr. 2,500 miles, city driving in Los Angeles. My average mileage is appr. 21.3 mpg. / 11+ ltr/100 km
Is anybody else checking their mpg?
This is not even close to the EPA of 33 mpg/city.
Mercedes says there is nothing wrong with my engine?

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.

are you putting 91 octane in ????

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.

Walter, take the car back to the dealer and request that they perform an MPG check for you. There's no charge for cars still in warranty.

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!

I'm getting 40 regularly and the lowest I have gotten is 37.

L. R., See my comment to Walter. Also, start pushing the car a lot harder. Your engine needs to be worked hard to loosen up and give you better mileage. Never mind the "soft-pedal" approach in "D". Go for the gusto in Manual mode. Works great in the get-away department, and believe it or not, you'll still get 37 mpg in town and have a lot more fun in the process.

I agree with you, Herb. At first I was gentle on my smartie and my mpg was mid-30's. After I got used to driving it, I started having fun and was hard on the gas pedal doing 70-80 mph, quick starts getting on to the freeway, and flooring it to downshift. Then my mpg started climbing. I do all hiway miles and I get around 43 mpg. If I keep it down to 65 mph, I can get 44-45 mpg. I did some city driving once and got 39 mpg. But I drive smartie hard and love it. And I might be imagining it, but I think that smartie has more pep now than in the beginning and I'm very happy with the mileage.

Syna,

Then we're both suffering from an over-active imagination (hehe). My Smart is a 2008 Passion and has the same mileage as your car. I can also swear that it has more pep now than when I bought it. I agree with all your MPG figures, and have managed 47 MPG on one all-highway trip with sustained speeds of 75-80 MPH (A/C was OFF). The A/C knocks about 5 MPG off the fuel economy. I tried setting the temperature lever to 75 degrees F. because will cause the unit to cycle on and off with hardly any effect on the comfort level in the car. However, it greatly reduces the MPG hit from running the temp setting at 60 degrees. I leave it set to 75 degrees and I live in Tampa, where summers are brutally hot.

I haven't had that problem here. Thank god. This city is full of Smarties - 4 in my neighbourhood alone - so I guess people are used to them.

We took ours through the Rockies to the BC (Canada) coast with no problem at all. Manual mode does work best.

Is Long Island part of the group. If so, I may be interested. I'm in the city quite often.
