Rivian R2 Performance Achieves Tesla-Equal EPA Efficiency, Extends Range

EPA data put Rivian R2 Performance at 105 MPGe (32 kWh/100 miles), tying the Tesla Model Y Performance in efficiency despite a taller, heavier SUV stance; the Rivian uses an 86.8 kWh pack for a 330-mile range vs. 306 miles for the Y with an 84 kWh pack, while 21-inch wheels deliver peak numbers and 20-inch tires cut efficiency to 99 MPGe and 307 miles; starting price is $57,990 and deliveries begin June 9, as Rivian touts weight-reduction engineering to offset aerodynamics and competition from BMW iX3.
