If you are used to the Passat and want another sedan, I'd suggest giving the Jetta another look if you want to stick with VW.
We've rented a few of the 8th gen Passat's (when they were offered), and couldn't find much of an improvement over the Jetta in terms of size/capabilities.
We usually rent vehicles and recently were given a 2026 Jetta, despite asking for a Camry.
My wife was initially unamused as seat comfort is her main objective, and the Camry is usually perfect for the job.
But after spending over a week and 3k miles with it, we were pretty impressed.
Not only was it roomy, but it performed quite well on the highway (especially the few times I ponied up for prem fuel...seemed to run much smoother).
Alternatively, if you are open to other, larger sedans, I'd go Camry/Accord.
YMMV
