New World Record - 1680 miles per tank

Thanks for that map with 1,000 km scale. He could've drove around the entire main island in one tank.

I thought that was how it was done. Is there a danger of doing harm filling the tank that full?

So... they shortened the filler pipe then?

We've never heard of any ill effects.
But, there's no guarantee. Do it on your own risk.

We know we can put more than 60 liters to raise the left rear wheel when filling up.
Please note that the 3G Prius could not accept such gain of gasoline.

Thanks, Ken! What is the fuel tank capacity of the JDM 3G Prius when the left rear wheel is raised?

Regarding the concern about emissions control damage, I think this would be a problem only if you overfilled, then immediately parked the car in the hot sun so that the gasoline could heat up and expand into the charcoal canister etc.

The computer mileage was 106.6 mpg (45.3 km/L).
2704km report (Japanese only BBS)

The previous world record was 1619 miles/tank.
New World Record - 1619 miles per tank

...

Great news! Thank you!

Just to make sure that I understand the record correctly: the record is for distance per tank, not distance per gallon, since the previous record already achieved 45.3 km/l, right? In other words this new record is for putting more gas in the tank, not for higher fuel efficiency, right? Of course I would be happy to get just a fraction of the mpg achieved.

Thank you, Patrick.
The official number is 45L on the JDM 3G Prius.
It looks the raised tank held the same 45L, but I saw my JDM 3G Prius held approx 47L when filled at flat surface.

So, the raised method lost some tank capacity on the 3G Prius.

You're absolutely correct. It was not the best distance per gallon or the best MPG number above 1000mile tank.

AFAIK, the best MPG number above 1000mile tank was 112.2mpg by TeddyGirl@Akita.
