New Polestar 4 platform information from Auto Express:

the brand outlined that the 4 will be based on a platform called PMA. Devised by parent company Geely, Auto Express understands that this architecture evolved into what we now know as SEA, retaining elements of the PMA platform when it comes to the vehicle product itself but incorporating more software and intelligent applications.

If this is the case, the Polestar 4 will be the first Polestar to be based on this architecture, as the Polestar 3 SUV will use the brand’s upcoming SPA2 platform, which will also underpin the Polestar 5.

Ingenlath admitted that the new Geely SEA platform - a purpose made, highly modular EV architecture designed for mass-market EVs and high volumes - is in Polestar’s warchest.

“The use of the whole bandwidth of technology is the beauty of being in this group, and Volvo, Polestar, Geely, we are all now free to look around and see what’s available.”

On the potential for the brand to use the new SEA platform, Ingenlath said: “That’s possible, and it will enable us to make cars that cater to different levels of the premium segment.

“But one is clear - the performance aspect of it is important for us. We have our own top-of-the-line powertrain that we implement in different platforms. We have our own bespoke idea of what a performance chassis should be on the road,” he explained.

The upper parameters of the SEA’s capabilities mean it is a platform Polestar could use and satisfy its need for high performance. It is an 800v electrified architecture capable of hosting small to large vehicles, with electric motor systems rated at up to 637bhp.
