I just picked up my 2016 smart last week. I tried to fill it up twice at two different gas stations. Both times the pump kicked out way too early. I knew by the amount of fuel pumped that my tank wasn't at capacity and sure enough, when I started the car, I was still 1/4 tank shy of a full tank (2 bars were missing for a full indicator). I tried in vain to top it off but the pump wouldn't let me. The dealership service dept blames the gas station pumps but I have my doubts. I will try a 3rd gas station tonight on my way home that is a different company from the 1st and 2nd. I looked on line and there are many issues on different types of vehicles regarding this same issue. I WOULD LIKE TO KNOW IF ANY SMART OWNERS HAVE HAD THIS PROBLEM ON THE NEW 2016 MODEL.

No problems so far on filling my 2016 453. Bars go to the top. FYI - This has no bearing on your specific problem but the 451 tank had a max capacity including reserve of 8.6 gals. The new 2016 453 tank has a max capacity of 7.6 gals so each bar now represents a bit less than one gallon. Your into the reserve when tank is down to 1.3 gallons. MIKE700.

I picked up my 2016 453 Thursday November 19, and have filled it up twice and yes I had problems both times so I am going to try parking with the nose pointed slightly up instead of down and pump the gas very slowly. By the way the 453 owners manual says the fuel tank's total capacity is 8.7 gallons.

Years ago, someone (not SCoA active since) physically removed his 451 tank and measured the total capacity, with reserve, at 10 gallons. IIRC, he posted a video or photos of the operation. I can't cite the post ... maybe someone else (jwight?) could.

But, I know it's over 8.6 or I would've run out of gas on multiple occasions ... hasn't happened yet. Plus, if it were 8.6 including the reserve the fractional bars (0.9, 0.8, 0.7 ...) should start after consuming somewhere around 7.6 gallons. That doesn't happen either.

I've run the tank to 0.0 bars numerous times and a few of those times managed to pump 8.5 to 8.7 gallons. I believe there is a reserve of a little over a gallon beyond 0.0 bars. I will NOT determine this experimentally. But, I'm glad it's there protecting my fuel pump when I run the gauge lower than I should.

But back on topic: At some pumps I have to ease up on the pumping speed quite a bit as I near full to avoid an early cut off on my 451.

Yes, confirmed a good bit ago at 10 gal for the 451!

With our closed systems now a lot of cars are sensitive to fill volumes.

I have the same "full" filling issues on my 2016 smart - as the pump will shut off without fully filling the tank

I have to fill it to the initial fuel stop, pull the pump handle partially out of the opening so that just about half of the nozel is in the opening, then proceed to fill it very slowly till it tops off.

This seems to be normal in the new 453. They all do it. Run it down to "0.0" and try a full fillup and you'll stuff about 5 to 6 gallons in before the fuel nozzle shuts off.

Assuming you filled up completely, you jump back in the car and drive away only to notice a block or two later that the fuel gauge is missing 1-2 bars.

Which means, there's still room for fuel. If you fight through the click, you'll get it to really fill up and the gauge is full.

i've pumped 9 gallons into my 451 with the warning on .8 gallons left. the capacity is 10 gallons. i use an ultra gauge and it verifies the usage and capacity.

Being from Canada, all specs are in Liters. the specs show 28/5, which I assume is 28L plus 5 L reserve. If this is the case, then it's the same total capacity as my old '08 smart. The only difference is the old smart was 30/3 (3L for a reserve). This means that the indicator bricks are calculating based on 2 less Liters before the reserve Liters kick in and start flashing at you. I haven't run the gas down to see if this in indeed the case.

I consistently get 9 gallons in my 2015 451. I usually fill up around 0.5 gallon and fill 8.5 gallons. A few times I've had spillover from the fill spout, but it recedes quickly.

I'm tempted to drive the car a few miles after filling up to see if I can get any more in the tank. Maybe I'll try that sometime.

I think that filling a tank removed from the vehicle is going to be different than filling it installed due to the shape of the tank, filling dynamics, and possibly trapped air. Meaning, just because the internal volume of the tank is 10 gallons doesn't mean you can get ten gallons into it in actual use.

And, yes, it is a bad idea to run the tank empty if the fuel pump or transfer pump is in the tank, it's hard on the pump.
