Rivian’s electric pickup and SUV officially have over 300 miles of range

Rivian will begin shipping its R1T pickup truck and R1S SUV "Launch edition" models to customers in a matter of weeks. You have to consider the internal estimates of Rivian before you make a decision about ordering one of these vehicles. This is no longer the case. After testing the R1S as well as R1T, the Environmental Protection Agency published their official range guidelines.
The EPA claims that the R1T can travel 314 mph (approximately 505 km) on a single battery charge. While the R1S can travel 316 miles with a full pack, it can be fitted with Rivians 135kWh power packs. Rivian will soon offer a Max pack that will give you approximately 400 miles per charge. The automaker promised that it would soon share details about its EPA certification.
