I bought my LC in South San Francisco et drove to Ottawa...Any experience with MPG at different speeds? 55 mph, 65 mph, 75 mph??? I might drive slower if I had a sense it would increase my mileage by a good amount.
Thanks,
Gil
the drag coefficient is approximately independent of velocity for a given shape if you stay in the same regime (turbulent, quasi-incompressible etc).
Therefore the drag force is approximately proportional to the velocity squared.
Therefore the power required to overcome drag is approximately proportional to the velocity cubed.
Therefore if you double the speed the power needed to overcome drag is approximately 8x higher.
