Something Doesn’t Add Up About The Rivian R2’s EPA Efficiency Rating

  • The R2 and Model Y share an EPA efficiency rating, but their real-world energy use differed widely.
  • The R2 lost every part of the comparison, including the low-speed test where the difference should have been smaller.
  • Different EPA test procedures may explain why the official ratings look more similar than the cars actually are.

On paper, the Rivian R2 matches the Tesla Model Y’s EPA efficiency numbers. That’s remarkable for the taller, boxier, and heavier R2, but the numbers don’t quite hold up in real-world tests. Side-by-side testing reveals the Rivian uses considerably more juice than the Tesla.
