Range-related BEV aero thought experiment

Always struggling to find some mental imagery that 'the man on the street' might connect with, I ran the math for:
1) A 2024 Hyundai IONIQ 5, with three (3) different body shapes, the IONIQ 6, the 1983 GM Aero2002, and 2013, Cambridge University Eco Racer ( CUER ).
2) All four cars have the IONIQ 5's weight, tires, frontal area, motor, and battery pack.
3) All four cars are reported for a constant 75-mph, in calm, 'standard air,' on dry, level concrete highway, 100% SOC, to 0% SOC.
4)
a) The IONIQ 5 returns 262-miles ( 420-miles @ 55-mph )
b) The IONIQ 6 returns 326-miles ( 504-miles @ 55-mph )
c) The Aero 2002 ( with Tesla mirrors ) returns 429-miles ( 631-miles @ 55-mph )
d) The CUER ( with Tesla mirrors ) returns 498-miles ( 708-miles @ 55-mph )
Wonder if public education might ever mention the relationship between Cd and the power vs velocity-cubed law to graduating seniors in high school?
