With its first production model, the grand-touring Polestar 1, soon to be leaving production, the Swedish-Chinese electric luxury automaker will soon be down to just one model: the Polestar 2. The next model in the pipeline, the Polestar 5, is a four-door sedan that will sit atop the model hierarchy and should debut in about two years. Polestar has been trickling out information about the upcoming sedan, including news that its bespoke chassis will be Polestar-exclusive and distinct from anything in Volvo’s arsenal.
