The fact that even with the shorter, lower hood line with the Y but still have double the space in the frunk of the large front end of the EV9 shows the thought Tesla put into engineering for the Y compared with the EV9
The Model Y L is the most aerodynamic efficient vehicle Tesla makes. It has a drag coefficient of 0.216.
For a comparison, a Kia EV9 has a 0.287 Cd, which is 27% higher than the Model Y L.
A low coefficient of drag mixed with high efficiency motors and other practices allows the Model Y to have competitive range numbers with generally smaller battery packs.
• Kia EV9 AWD: 99.8 kWh battery - 283 miles of range
• Tesla Model Y L: 83 kWh battery - 325 miles of range
Tesla is all about efficiency.
