I come from a hot hatch and sport compact background too, never owned a Golf/GTI/R but I'm with you all in spirit on this jump to Model 3 EV.
And yes I absolutely miss having a liftgate! After my first car with a liftgate I vowed to never bother with a sedan again. I kept to that for 15 years, and I was all set to continue with a Polestar 2 Performance (which is a fastback). Then Tesla restocked their Model 3 demo fleet and within a few blocks I realized I was cancelling the P2 order and buy another Tesla.
(We had tested a Model Y earlier and I hated driving it. It's
not a Model 3 hatch, despite looking like one.)
Model 3 and Polestar 2 seem by far the closest EV experiences to a sport compact or hot hatch. Honestly we couldn't do the Model 3 as an only car, the trunk is too restrictive and the back seat is too low for taller adults on trips, but as a 2nd car it's really great. Big stuff continues to go in the 2013 Model S P85.
@dave999z Your list is exactly what I miss from my ICE hot hatch, with one addition: Traction. Compared to the best AWD systems I notice the Model 3's open diffs on hard corner exits, and I'm guessing I'll really notice them in the snow too. I don't want limited slip diffs in an EV though. When someone comes out with a sporty, compact EV with quad motors I'm there!
