The 2010 has a dedicated pump for controlling evaporation.

Toyota has been doing AT-PZEV without the bladder since 2005. The 2006 Highlander Hybrid and the 2007 Camry Hybrids are AT-PZEV and have no bladders.

They seal the gas tank well and I believe that they then suck the vapors into a charcoal canister or something. When the ICE is running I believe that they then burn the vapors off by feeding them into the air intake.

Or something like that.

The bladder is obsolete...

it's a shame they didn't increase it just a tad, say 12.9 gal..but its no biggie. At least now the car has a consistent fuel tank.

This is one big draw for me to trade up, But Im waiting till 2011. I was going to get a different car, but I will keep this one and get another prius after plug in most likely. Or wait longer for the coupe

Hi all,

The maximum capacity reported by Ken@Japan is 60,8 litres.

The maximum I have ever made was 57 litres, but I flooded the return pipes while doing so without noticing it, not good.

I can put consistently about 48 litres without any hassle: I try to go to the gas pump the least I can. I always wait for the last dot to start blinking, reset one of the trip meters, and wait for 100 km to go by.

The reserve, again as reported by Ken is 6,5 litres. Doing 100 km is a no-brainier since I hardly get close to 5 litres per 100 km (doing now 4.2 on current tank).

That makes me wonder whether the quoted 45 litres, and gauge calibration, is to the top of the fuel pump's cooling pool. 45 litres is 75% of 60 litres and it's supposed to need a 25% sump of fuel to submerge the fuel pump, to keep it cool and to prevent it sucking air, preventing it being damaged.

Generally I refuel with two blobs remaining on the fuel gauge, which is about 35 litres. That's still normally over 400 miles of range.

I get over 900km out of a tank now, that is 41 litres at most, can't complain about that!! If I get 10% better from a 2010 that's 1,000km or about 600 miles, how can anyone whine about that? No doubt they will.

You can check this text table here:
Luis Alexandre - Prius-PT

Never mind about the post text, the table has 3 columns: Gauge dot, litres left in the tank, litres that one dot represents.

10 dots (full gauge) represents 47,8 litres of fuel.

We created a sub-group at our Prius-PT community for members that have proved to do over 1000 km with one single tank. A kind of hiper-miler prize, with our own logo and all:



There are not many there, but it is not that hard to achieve:

I bet you can do it too, you just have to let it run into reserve

Damn it!!! My best is 902km with the bladder! I refuelled 40 or 41 litres at that time. Another 100km on a normal tank without the bladder is possible.

Not much we didn't know already but here's a new article talking about the gas tank in the 2010. I've never had it click off while filling up from just one bar after 7 gallons went in like the woman in the article...
