I traded a 2012 P85 for the Ioniq 6 and I regret the decision every day. The P85 was starting to have a few issues so I traded it in. My overall experience, not even including the charge post overheat issue I had, was that driving the car was like death by a thousand paper cuts. So many things that are automatic and taken for granted on the Tesla have to be manually performed on the Hyundai. Below is just a quick list of what the MS had over the Ioniq 6:
Useable frunk, remotely opening frunk, rear trunk opens completely not just small trunk, sound system with amp is much better than Bose, passive lock, no start button, no stop button, regenerative braking stays on every drive unless changed by user, user adjustable height air suspension, suspension height can be set to change automatically by location, can easily carry 900 LBS (cement board sheets) in trunk and air suspension automatically levels car, automatic garage door opening and closing by location, remote charge current changes by app, charge settings stay separate based on location, acceleration speed, reliable native fast charging network, built-in infotainment, charge port works at 48 amps level 2 and doesn't overheat, various stay-on HVAC modes, evolving OTA updates, excellent maps, routing with fairly accurate SOC at all locations, car will precondition by settings without being required to be plugged in, no app to start Supercharger, can just drive off after Supercharging without restarting car, can operate car fully with just the app, automatic wipers, easy entry, cloud based profiles that save nearly every car setting, profile can be applied in other models even Hertz rentals, key remote that is not huge, user-friendly gear selector, can go from R to D without hitting brake, charge door opens by touch of button on EVSE handle, charge door closes automatically (right when complete not several minutes later), detailed energy useage info, $100/day in Uber IF loaner Tesla is not available during service visit (not sure if this still exists or not), no dealers that don't have a clue about electrics...
I feel like such an idiot for not researching the E-GMP line further.
