How many MPG are you getting at 70 mph (GPS)
Just a poll to see where everyone is at!
Also to add oem speedo's read 2% fast. So if you're going off an accurate oem speedo 71.4 displayed = 70 actual
Comment what vehicle sub trim and what ambient temp for your vehicle.

Translate to ton-miles. That, at least, provides context.
Payload expressed as tons (percentage thereof) X fuel burn
1,280-lbs payload my pickup
with driver X 20-mpg (@70) = 10 ton/miles per gallon.
150-lb EM’er X 45-mpg (@70) = 3.3 ton/miles per gallon.
When I hitch the trailer (8k), it shoots to over 60 with four passengers also present.
Four persons uncomfortably aboard
an air-conditioned go kart hits a staggering
21 T/M gallon.
Loserville is a town of single person vehicles.
Fuel burn or fuel type just doesn’t matter.

* 40mpg plus vehicles are the focus

I dunno! I only drive 70 mph a few times a year, when on long (multi-day) trips.
The rest of the year, I toodle along the scenic side roads at ~50 mph / 80 km/h.
But theoretically, an unmodified 5-speed Mirage is good for ~42 MPG US @ 70 mph on level ground in warm weather.
The Metro/Firefly (unmodified) is about the same. |

An unimportant context on this particular forum. Perhaps makes sense elsewhere, though. |

I recently broke 50mpg at 70 in my Acura TSX swapped Insight on a longer trip. It's hard to know if there wasn't some external factor like a tail wind. MPG at that speed seems pretty variable, I've seen as low as 46, but road conditions in winter are highly variable. I'm willing to bet 50+ in summer will be normal. Could probably break 60+ with P&G.
My other (stock) Insight easily maintains 65-70mpg in winter at 70mph.

I’m not even on your chart but I still enjoy and try to contribute to this site. Been here a long time, I do not own a Metro any longer.

Amateurs.
I get around 120mpg at 70mph in the summer in the leaf.
To be a little more fair my wife's hybrid sonata gets around 40mpg, during the summer at 70mph.
