Once the Volvo takes the lead, the Polestar usually follows. But that’s not the case this time, as C/D drove the new Polestar 3 (in prototype condition) before experiencing the closely related Volvo EX90. The complete version of Polestar’s all-electric SUV will arrive in the U.S. late next year, with the EX90 also expected to go on sale later this year.
