The Rivian R2 is one of the most important EVs introduced in the past few years. It takes some impressive engineering to create such a car, engineering that's well worth digging into for nerds like us. Dachner explains the battery, its rigid structure, and even the suspension components that make the R2 such a compelling package. What is interesting is just how far Rivian went with it. Rivian also went to painstaking lengths to engineer the R2's powertrains and subframes.
