Rivian was recently contracted by Amazon to build some 100,000 electric delivery vans. Well, if you're already building a big van, then why not venture into the motorhome segment too. That's precisely what we see here in this render.
It's not much of a leap from a full-size cargo van to a motorhome. In fact, the Sprinter van is one of the most popular motorhomes out there and presumably this Rivian electric van would be of similar size to the largest Sprinter offering.
With this size vehicle, a whole lot of battery can be fitted. If Rivian chooses to go the electric motorhome route, then the automaker would likely offer several range options, each with different battery sizes, as it will with both the R1T pickup truck and R1S SUV.
But the Tesla Semi will be a low volume vehicle, so we don't see Tesla venturing out into this segment. However, with Rivian's 100,000-unit order already out there for a big electric van, the transition to a motorhome would come with relative ease.
