2023 Rivian R1T: Car and Driver 10Best Trucks and SUVs
The great-driving and fully capable R1T is a perfect pickup.
C&D felt the poorer handling and less compliance was due to the shorter wheelbase of the R1S versus the R1T, and they also made mention of more motor noise noticeable in the rear of the R1S iirc.I'm curious too.. not sure if this is it but I have seen some reviews that say R1S ride quality is not as good; oversteering tendency, bumpier ride, more audible road noise etc. I am hoping this isn't a common experience for a majority of R1S owners. Now I really feel like I have to test drive first.
