This means if you change the aero of your car and make it 100% more slippery to the wind, it will gain you 50% more gas savings, because while the aero part improved 100%, the Crr part stayed the same. Then when you add the new Cd and the old Crr, you have a 50% net gain.

Thanks, I didn't know how the rest broke down because honestly I can't do a lot to change it. Now, aero, that's something to easily improve upon
