Huh? The model 3 didn't come out until 2017 and the model Y came out in 2020. That's literally just four years ago - not 2012.
I own a 2019 model 3 and will be replacing it with a 2024. In those 5 years, it's accumulated a bunch of improvements. I don't exactly have a changelog to work with, but here's what I can think of off the top of my head:
- more powerful rear motor, 10% faster 0-60, breaking 10s quarter mile
- track mode v3
- heat pump
- matrix headlights
- adaptive suspension w/ frequency response suspension dampers
- ryzen media control unit
- triple pane glass
- heated steering wheel
- sport seating
- ventilated seats
- usb-c ports
- rear entertainment system
- HW4
- updated wheels/tires
- exterior styling updates (front bumper, non-chrome handles, etc...)
- interior styling updates (LED lighting, carbon fiber dash, etc...)
Oh, and there's also the fact that I'm only paying 70% of what I did the first time around (inflation adjusted).
