AC/blower on effects my engine
I don't know how to describe this accurately....
When I drive with the AC and/or air blower off, I move through the 5 gears smoothly. With the AC/blower on, I get coughing, hicccuping and it feels almost as if the engine will die (especially in 1st and 2nd gear).
Is my Smart broken?
It has less than 100 miles on it and is 3 days old.
Thanks for any feedback and advice.

Holly, Don't worry the smart gets better with miles. When you hit 800-1000 miles you will think it's a different car(power, shifting etc all improve).
As far as mileage and running the A/C.. I see a real world 1.5 - 2 mpg reduction with the A/C on 100% of the time and a slight slow down in acceleration. Nothing to wory about.

Shoot. I'm at 800 miles now and I was thinking I was getting better at shifting.  I am guessing that riding around at highway speed with the top down isn't helping my mileage either, but it sure is fun.

My salesmen told me the EXACT same thing so I put my hands on his sholders and pulled him real close so he could not get away while I raised my knee into his crotch three or for times. He still did not look convinced so I laid him on the pavement and stood on his neck for a minute while I maced him a little. I thought I was done but he started mumbling somethign about "tire protection" so I went back and kicked him a few times and he calmed down after that.
I only recommend this course of action in the case of extreme salesman stupidity. You can usually avoid dealing with it by not asking them any questions and just walking away if their lips start to move.  
Oh, yeah. My scangague shows an almost instantanious 4mpg drop when I turn on the AC and none of the AC settign seem to make any difference. Hi, medioum, low, recirculate... It all seems to result in a 4 mpg drop.

That seems reasonable to me. My driving style has not changed from my previous car to the smart. I am getting about 34 to 37 in a combination of ~40/60 highway and city driving AND the air is ALWAYS on. Am willing to sacrifice a few MPG's for comfort and quiet and no windand dirt from open windows.

Thanks for the reassurance! I do love this car, but all the plastic makes it feels a bit fragile. I guess I haven't had time to build up trust in it yet.
Glad to hear the hiccuping and hesitation is typical.

I'm sure the pure weights a bit less then passion or cabriolet.
About the glass roof on the passion models being heavier I can't say I know the exact weight difference betwean them but the passion has a thin polycarbonet roof, same type of material used on most prescription glasses, very light compared to tempered glass.

Well this makes me feel better
Down here in FLA, I am already driving with the A/C on constantly more or less. It is good to know I can expect to realize some better gas mileage in the fall when things are cooler.
