This is the chart MetroMPG was talking about. These are the default values for the chart, I believe they're for a Geo Metro.

At 45 mph 70% of your power is going to overcome aero losses! You have to slow down to ~29 mph to even get down to 50% aero losses. Aerodynamics are huge even at low speeds.
