Rivian R2 matches Tesla Model Y efficiency despite bigger, heavier body

The Rivian R2 Performance’s final EPA ratings are now published, and the numbers confirm something impressive: the R2 Performance matches the Tesla Model Y Performance on efficiency at 105 MPGe combined and 32 kWh per 100 miles — while actually beating it on range with 330 miles versus 306. What makes this particularly noteworthy is the R2’s form factor. The Rivian is a boxier, taller, more utilitarian SUV that weighs nearly 800 lbs more than the Model Y, yet it achieves identical efficiency. more…
