Rivian R2 vs Model Y: EPA Parity on Paper, Real-World Energy Gap

Tests show the Rivian R2 and Tesla Model Y share the same EPA 105 MPGe rating, but real-world energy use differs significantly: at 50–80 mph the R2 consumed roughly 18–26% more energy than the Model Y, and over about 30 miles the gap was ~26.5%. Explanations include potential differences in EPA testing routes and data inputs, plus the R2’s off-road design and ability to disengage its front motor. The study’s methodology—relying on on-car energy figures and short routes—means the exact gap isn’t definitive, even though the Model Y remains more efficient overall.
