I dated an vehicle design engineer once. She told me that cars create drag at a logarithmic rate at basically for every mph over 80, most people design them to use nearly double the fuel consumption to maintain. You can get some aerodynamic cars that are designed for 90mph, but it’s pretty rare in the consumer space. This was also nearly 10 years ago and I could be remembering it wrong.
- r00fus 5y agoDrag is the square of velocity, so not sure how your former date got logarithmic for that, sounds quadratic. Equation [1]: F(d) = 1/2v^2CdA Lowering the Cd (drag coefficient) and area can significantly reduce your drag.

- withinboredom 5y agoI think she was talking about fuel consumption and drag, not just drag. But like I said, it was a really long time ago.
