But the changes also raise some questions.
Rivian owners and customers have a pleasant surprise waiting for them. Rivian has released an update for R1S and R1T models with AWD. The brand's large battery pack will net an increase in range. These numbers are also reflected in Rivian's online configurator, which we encourage you to go play with, as there are also a litany of changes there.
Rivian's larger battery option originally offered 314 miles or so of range for the R1T, with the R1S benefitting from an extra two miles of range. Now, the R1T shows an estimated 328 miles of range, with the R1S showing 321 miles of range. That is a 14 and five-mile increase, respectively.
However, Rivian's quiet changes leave us with some questions. The brand has removed range estimates for the dual motor, large battery option combination for both models. Earlier, the brand claimed more than 320 miles of range for the two. Rivian has also removed the full-size spare option from its configurator.
The latter makes us think supply issues are to blame. Rivian has had issues with suppliers in the past, as have all automakers. But that doesn't explain why range estimates have been changed for the dual motor, large battery configuration. Likely, these bumps in range estimates are the result of a recent over-the-air (OTA) software update that has made the vehicles more efficient.
An update earlier this month did mention some improvements to the range, listing "Improved battery longevity, battery durability, and regenerative braking performance" as benefits of the update. It also claimed "enhanced regen availability, and you can use regen for longer durations."
However, there is one last asterisk to the good news, which is the range bump. Rivian has removed nearly all of the R1T and R1S' add-ons from the configurator. Previously, you were able to spec your six-figure truck or five-figure SUV with a roof tent, cross bars, and the spare tire mentioned above. We do know that the gear tunnel and kitchen are being redesigned. Rivian has not given any clarification for these changes at this time.
