CX-5 Suspension Question 2020 AWD vs 2017 FWD

My 2020 AWD seems to handle a tad smoother than my 2017 FW. Did they upgrade the suspension in the 2020 model as opposed to the 2017 or is THE AWD suspension different or is it a combination of both?

thanks

Is it possible just because the older car deteriorates over time, and so when you drive a newly built car it feels different? Cuz I think within this generation they are mechanically the same.
