Back in February, Amazon helped Rivian by investing $700 million into the company. Now Amazon is helping further with one first big order. Amazon is ordering 100,000 vans to be delivered by 2024. The first deliveries should start in 2021 and prototypes will likely be seen next year. At that rate of production, Rivian would immediately start outselling the Nissan NV and NV200 combined. The van is exclusive to the Amazon partnership and Rivian says it will not delay any of the R1T or R1S deliveries as it is being built on a separate assembly line at the Normal IL. facility.
Rivian used a skateboard chassis for their R1T and R1S, so building a van body (R1V?) over top of the skateboard shouldn't be too hard of a task. The R1T has a claimed range of up to 400 miles on a single charge and being capable of getting to an 80 percent charge inside of an hour.
Amazon's use for the vans is clear. They have committed to reaching the goals of the United Nations Paris Agreement 10 years early with 80% of their energy use being renewable by 2024 and 100% by 2030.
