As mentioned in the "Rivian announces electrochromic glass roof for the R1S and R1T" thread, Rivian's tweet response was straight from its website's FAQ section. Go to https://rivian.com/faq/ then on the left click on Products and scroll down toward the bottom and you will find the following:
Note how Rivian framed the FAQ question to be non-specific to either EAV, implying the roof options available will be for both. But unfortunately like most of the Rivian information that's available today it lacks details and this roofing answer is no exception.
So as for which one I would choose / vote for, hard to say at this point without more details. For example ...
- Are all these options indeed available on both the R1S and R1T? If so, how do they differ? Clearly the R1S roof is larger than the R1T roof.
- What's the price for each option (except "standard fixed roof" which I expect to be standard)?
- How is the removable roof configured and how will it work? E.g. Does it store itself within the vehicle or does it get left behind? The R1S is a big roof.
- Will the fixed glass panel come with a sun screen/shade or will one even be needed?
- Etc.
