Polestar has announced a partnership with SK On in which the South Korean battery manufacturer will provide battery cell modules for the upcoming Polestar 5 electric 4-door GT.
Polestar said its decision to collaborate with SK On stems from the company’s reputation for advanced battery cell technology. The high-nickel battery cell modules they offer boasts high energy density, ensuring high performance, fast charging capabilities, efficient discharging, and, perhaps most importantly, improved driving range.
The battery cell modules that will be packed into the Polestar 5 are their ultra-long 22-inch (56 cm) cells. This unique format differentiates them from the standard cylindrical cells used in most EVs, such as Tesla’s 4680 cells. The elongated design aims to optimize power, efficiency, and safety credentials.
“Our relationship with SK On has been fruitful following our initial MOU and their investment in our brand. Polestar 5 is developing at pace and will feature this high-capacity battery to provide the performance expected of our grand tourer,” said Thomas Ingenlath, Polestar CEO.
The automaker also revealed today Polestar 5 is scheduled to start production in 2025, later than their originally announced date of 2024. All of the details haven’t been finalized or released, but according to Polestar the electric GT will include a new rear electric motor built on an 800-volt architecture. Combined with the front-engine, the Polestar 5 will deliver 884 hp and 663 lb-ft.
The Polestar 5 is being introduced to the public through a YouTube documentary series titled “From Concept to Car,” offering an inside look at the car’s journey from the Polestar Precept concept car to reality.
