The Rivian R2 Is A Charging Beast. But It's 'Just Fine' At Road Tripping

• The Rivian R2 is finally here, so we're starting to see real-world testing.
• The Out of Spec YouTube channel put the EV through its "10% challenge."
• They found the R2 charges impressively quickly, but its highway efficiency is worse than the Tesla Model Y Performance.

Rivian's decision to stick with 400-volt battery architecture for the new R2 might have raised some eyebrows when it was first announced. Since many high-end EVs have switched to 800-volt architectures, the R2 seemed to lag behind despite being among the newest EVs on the market. But a new test shows the R2 is a charging beast.
