Showing the impact of Mirage drag coefficient on fuel consumption
So, we've seen that the car's Cd varies from 0.27 to 0.31.
How about looking at the effect of that number on fuel consumption?
I plugged the car's figures into the Aero/Rolling Resistance/Fuel economy calculator at EcoModder, and here's what it spat out, using these constants:
- Frontal area of 2.04 sq. meters / 21.97 sq. ft.
- Vehicle weight of 935 kg (865 Australian spec. curb weight + 70 kg driver) / 2060 lbs
