Speed vs. MPG

Here it is!



Notes:

- Values are averages of bi-directional runs on a level road *
- (* except the highest speed reading - 1-way only - consider it an estimate)
- Weather: 21 C / 70 F, dry, with negligible wind
- No traffic ahead in my lane (no draft / aero effect)
- A/C off
- Driver only on board
- Headlights on
- Tires at manufacturer's recommended pressure (35 PSI)
- Readings were taken from the car's MPG display (which was within a few % of calculations at the pump based on 2 fill-ups).

This car seems to fit the pattern of some small displacement cars: very good low/moderate speed results. But MPG really falls off a cliff (relatively speaking) as speed climbs.

EG: at the highest speed of 120 km/h = 70 mph, this car reports very close to the fuel consumption of my folks' much bigger 2004 Toyota Camry 4-cylinder:



Though that Camry's gauge wasn't calibrated against actual fill-ups.

Also, in sub/urban driving, the Mirage's real world fuel economy is almost twice as good as the Camry's.
