Do you have the 21 inch or 19 inch wheels? Do you notice any change in feel of the ride?Both the trunk and frunk are shallower in the 2023 than in my 2016. I looked it up:
2016 Tesla Model S/Cargo volume
26.3 ft³, 60.2 to 63.4 ft³ with seat area
2023 Tesla Model S/Cargo volume
25 ft³, 64.6 ft³ with seat area
The higher volume with seat down is probably on account of the slightly greater length and width of the new car.
