Polestar 5 EV To Be Based On New Aluminium Platform

Polestar, the Swedish premium electric performance car maker, has confirmed that the forthcoming Polestar 5 electric performance 4-door GT will feature a brand-new, bespoke, bonded aluminium platform. Bonded aluminium is light-weight and rigid, offering superlative performance and environmental advantages. While this technology has previously proven labour-intensive and difficult to use in mass production vehicles without sacrificing quality, Polestar's 280-strong team of former Formula 1, low volume and bespoke sports cars engineers working in the heart of the UK's Motorsport Valley in the Midlands have resolved this challenge by developing an entirely new, faster manufacturing process that develops both body and platform in unison.

As a result of the new materials and techniques involved, the body-in-white (completed platform and body) is expected to weigh less than that of cars in smaller segments, contributing to improved vehicle efficiency, real-world EV range and dynamic responsiveness, all while delivering leading safety levels. The new bonded aluminium platform will also help drive faster product introduction, high quality and platform rigidity.

By further developing this technology for Polestar's first in-house platform, the 4-door Polestar 5 is being designed with torsional rigidity superior to that of a traditional two-seat sports- or supercar. The decision to develop a bespoke platform has also enabled the brand to deliver a production model that remains true to the Precept concept car that inspired it.

Development of Polestar 5 continues at pace, with global efforts led by a growing UK R&D unit, which is expected to grow to approximately 500 engineers in the coming months and will continue to play a critical role in enhancing Polestar's in-house R&D capabilities.
