Hello - I am a new owner of a pre-driven '15 500 Pop w/auto and 14K on the odo. I am getting 17.2 mpg so far on my 1st full tank! I only drive him a few times a week for around town errands, and I have been aggressive with the pedal because this car is so fun to drive! I am having a hard time believing this!

so you're driving WOT from red light to red light around town (short trips?) and you are angry you're not having 30+ mpg highway crusing numbers? jestera

These cars are made to have fun first and then get great gas mileage second. The more fun you have the less gas mileage you get, but it may pay to go over a few things while you are at it. Check the tire pressures to make sure they are correct. Oil needs to be the correct weight and it should have been changed a few times since new. For a 2015 it is every 12 months or 10,000 miles unless the oil change light comes on- whatever is sooner. I would also make sure the brakes aren't dragging. You can check that at a street light on a road with a very slight incline by shifting to neutral and easing off the brake to see if the car will roll easily. When it starts to roll, step on the brake and then ease off to see if the car starts to roll again.

You should also check your mileage the old fashioned way by filling up, recording the mileage, then drive and fill up again and record the mileage. The trip computer is likely to be off. To be accurate, you should use the same gas pump, the same time of day and stop filling as soon as the pump turns off. Squeezing gas into the gas tank on new cars can cause issues if the tank is overfilled. It will also affect your accuracy.

Check it out and see how you do. There are also all sorts of techniques you can use to boost your gas mileage, if that's important to you. If not, have fun!

Thanks for all your input. I was not expecting 30 mpg, but I also was not expecting 17.2 with spirited driving. This is my first 4 cylinder car in over 18 years. I will try a tank with prudent driving and I guess this will give me more of an idea on mpg.

You probably have a brake that's sticking or some other problem. I can't even get that low in my Abarth which is way more fuel hungry. And I don't drive it with MPG in mind.

That is NOT normal. I have a 2012 Lounge with 100k miles and I drive with a lead foot. Never had anything lower than 30mpg.

I experienced unbelievably good mpg mostly city driving in my former 500P 5spd. I never saw less than 32mpg with the horrible winter mix and driving conditions. I didn't drive her like I stole her, but I flogged her from time to time (mixed with otherwise eco-friendly driving). The best conditions and driving habits took me into the low 40s.

One can easily get 26-29mpg in a stock A500 and still have plenty fun.

What you're seeing is most definitely not normal.

My Pop does really well, even with my lead foot. The worst I've achieved around Houston (flat) is ~30mpg. It did struggle some with the steep grades in the Hill Country and being driven at full tilt but even then it did better than 17mpg.

My Abarth (phase 3, turbo upgrade, ~250whp) will happily chew through the gas in the sub 20mpg range though.

My lifetime mileage is 32 mpg with over 55K recorded on www.fuely.com I guess just about anything is going to get bad mileage if your doing an "Italian tune up" all the time, LOL!

It's definitely me and not the car. I have tried the disciplined approach and got great results (47mpg in the Pop and 35mpg in the Abarth), but the cars are just too much fun and I can maintain that.
