The Rivian R2 is rolling out to the public, and that means we're starting to see more real-world tests. The Out of Spec YouTube channel subjected the R2 to a 70 mph range test. It didn't go as far as its main rival, the Tesla Model Y Performance. They took out the R2 Performance with Launch Package (the only version available) out at a sustained 70 mph in North Carolina. (Interestingly enough, that about matches another 70 mph range test we covered, involving an R2 on knobby all-terrain tires.)
