4.2 L/100km / 67 MPG on my 2016 prius v 7 seater : D

That's good - I used to get excited when I first got mine, but then realized after tracking my averages manually calculated via Fuelly.com, that my actual l/100km was 0.5 to 0.7 more than what was diplayed in the car. That has been consistent after 1 year of tracking and using different gas pumps. Nonetheless, it's still excellent

 

I have to work hard to get 4.2 displaying on my regular Prius.

 

I've had it down to 4.0... But couldn't keep it down that low for long. In my Area the most fuel efficient Drive to work is now closed for 2 years due to a bridge being replaced. so now i have to face a couple of hills every morning.. 4.2 Was very easy to get in the summer time. CAr gets amazing mileage in the summer... Wish i could have warm weather all year round.

 

Curious. In the US with mpg, I think people find the dash number about 5% high. The once I calculated my mpg, the dash was 10% high.
This is the first time I remember somebody saying the dash value is lower than actual.

 

You have higher MPG number than actual and he has lower l/100km number than actual. Both are in the same direction in terms of economy.

Mine displays 7% lower than actual (l/100km).

 

Ah. Thanks.
Higher MPG == more fuel efficient
Lower l/100km == more fuel efficient
