The EV maker will conduct powertrain development for the Polestar 5, a Tesla Model S rival, and the Polestar 6 roadster at a 15,000-square-meter building in Trollhattan, Automotive News Europe sister publication Automobilwoche reported.
Polestar will also test powertrains, electric motors and batteries for the upcoming models at the new R&D center.
Polestar will rent the building from the city of Trollhattan, Automobilwoche said.
The site was previously used for powertrain development by Saab and then by National Electric Vehicle Sweden (NEVS).
Saab collapsed in 2011 and NEVS closed down last month.
Polestar also has R&D facilities in Gothenburg, Sweden, which is about 90 km south of Trollhattan, and in Coventry, England. In England the automaker is developing its own lightweight bonded-aluminum platform that will underpin Polestar 5 and Polestar 6.
The Polestar 5, which will also compete against the Porsche Taycan, is scheduled to go into production in 2024 at a plant in Chongqing, China. The Polestar 6 hardtop convertible will also be built at the plant, likely starting in 2025. The plant is owned by Geely and operated by Polestar. Polestar's new platform has not been named yet.
The cars will share an 800-volt electric architecture that in addition to providing nearly 900 hp of power will offer 900 newton meters of torque, 0 to 100 kph (62 mph) acceleration in 3.2 seconds, a top speed of 250 kph (155 mph) and an estimated range of more than 480 km (300 miles), the automaker said.
