Rivian sent out an email to customers today saying that they won’t be building R1T pickup trucks and R1S SUVs with the “Max” pack (400+ mile) battery option until 2023. Instead they will prioritize "Large" (314+ mile) battery pack models to meet the higher demand, according to CEO RJ Scaringe.

"As of December 15, we had approximately 71,000 preorders for the R1T and R1S in the US and Canada, with the large majority having configured an Adventure Package with a Large pack battery (our Max pack represents approximately 20% of our preorders). In order to serve the largest number of preorder holders, we will be prioritizing building the Adventure Package with Large pack battery during the next year. Explore Package preorders and vehicles with a Max pack battery configuration will follow in 2023. In setting our delivery timing, we optimized our build sequence around the build combination that would support us ramping as quickly as possible and therefore have the largest possible positive climate impact."
