please explain this

Two of my trips coming home from work in Atlanta interstate rush hour traffic.

Here's my best tank showing 61.0mpg. Actual calculated was 57.8mpg

 

In my case, slow moving traffic helps.

My overall average for my car up to now (just crossed 5000mi) is right over 50mpg. It was 52+mpg until we went on our beach trip last week which resulted in 44mpg and 42mpg fill-ups driving interstate at 80mph. The car was loaded with 3 adults, a child, and all associated luggage. The hatch was packed to the top.

 

Is that pic from a UK Prius?

 

For my 600 mile tank picture above, I would say this is accurate. Atlanta interstate rush hour usually is a crawl with some 60+mph bursts. The 600 mile tank was achieved in traffic. I couldn't have done it running 55-65mph everyday. Notice the average speed is 30mph.

What's even more amazing are the folks on this forum that are able to get 700 and 800 miles on one tank. I think someone even has done 1000 miles in one tank. That's some extreme hypermiling.

 

Good catch.

That means that 68mpg shown is actually lower in relation to the US gallon.

 

i don't understand the question...

 

1 Imperial Gallon=1.2009499 US Gallon.

 

if the question is, how do you get 68mpg on a lift back, it's easy. i used to get 65 regularly in my '08 and can get over 70 in my pip with no wall charge. you can't go by your own experience, there are too many variables. but, i don't know if that's the question.

 

it's not a matter of how, it's all about terrain, speed, stop and go, acceleration, climate, etc. i can't do what wayne gerdes does, and he can't explain it to me.

 

If 68 MPG blows your mind, don't read this thread: 99.9+ Trips

While my 2010 Prius was new, I did this trip, 3000 feet gross climb but zero net elevation change for the round trip:

In the next several years, I achieved a number of commutes, 36 miles round trip with two cold starting, in the 72 to 76 mpg range. But these required favorable weather and traffic conditions.

Plenty of others can do better. Multiple Japanese hypermiling commuters have beaten 100 mpg for full tanks.

 

Referring to the OP's photo, the car got 68 mpg on an Imperial gallon. On a US gallon, that would be around 56-57 mpg.

 

68 MPG-UK is about 56.7 MPG-US. But even 68 MPG-US is possible, just on the high side of the normal distribution.

 

a man can dream, can't he?
