Yeah.. the 23 Ys have a slightly better suspension but it is the current weakness of the 3s and Ys... the NVH is Toyota-level.
After a month with the Ioniq 5... my original assertion that the Y, Mach-E, Ioniq 5 are basically interchangeable stands. They all have flaws and strengths but nothing stands out. My (former) BMW i4 does everything better than the all the above except maybe cargo space. Better suspension, quieter, better interior, better handling.
Ioniq 5 pros:
Quiet (Model Y and Mach-E are not well isolated)
Softer suspension (Mach-E is bouncy as fudge and the Y is microbump firm)
360 camera, rear cross traffic alerts, blind spots.
Cons:
The top trim Limited has a subpar audio system (Mach-E is better, Y is even better, BMW i4 a notch above those)
One pedal is janky and not smooth. Mach-E has unsmooth 1PD coming out of a stop and Tesla's acceleration curve is not entirely linear but it is the best of the three.
Range is the worst of the three and efficiency is as poor as the Mach-E. Mach-E has the same range as the Y because of the 99 kWh battery.
