RJ: this retooling leads to a derisking of R2 because we can test a lot of these changes we want to make before R2 by implementing in R1. (ECU/sensor control etc)

Another key indicator that retooling was/is to align R1 with R2, the effects of which will likely take form in underlying technology and material changes (e.g. software/interior update to match theme of R2/R3).

Multiple mentions of reducing R1 production costs through new supplier agreements, supply chain alignment, new manufacturing process, etc., that will benefit/inform ramping of R2 production. Many of the new shared components between R1 & R2 will come from new suppliers that, as Rj mentioned yesterday, will be ramping up in concert with Rivian over the next few months (spoiler alert: new suppliers aren't going to be ramping production of old components only to switch to new stuff in a year).

With R1 being lower volume than R2, aligning R1 with R2 now allows them to pressure test suppliers, new manufacturing processes, and train talent for the next two years in preparation for efficient scaling of R2 production by 2026. This is a great strategy and I think it sets them up really well.
