Polestar's New Platform Inspired by Supercars

Polestar is a little-known Swedish premium electric performance car maker, an offshoot of Volvo Cars.

In news this week, Polestar 5 electric performance 4-door GT will be manufactured on a brand-new, bespoke, bonded aluminium platform.

Bonded aluminium is light-weight and rigid, with performance and environmental advantages. Previously, this technology was labour-intensive and difficult to use in mass production vehicles but Polestar is developing an entirely new, faster manufacturing process that develops both body and platform in unison.

The reason that this is so important is the body-in-white (completed platform and body) should weigh less than that of cars in smaller segments. EV need to be as light as possible in order to compensate for the weight of battery packs. This increases range and efficiency, and of course, cost. The new bonded aluminium platform will also help drive faster product introduction, high quality and platform rigidity.

“Our UK R&D team is one of Polestar’s greatest assets,” says Thomas Ingenlath, Polestar CEO. “Their mix of engineering and technological expertise enables us to develop advanced, light-weight sports car technology with a creative mindset and a spirit that embraces innovative engineering. This will set Polestar apart in the years to come.”

This is Polestar’s first in-house platform, and the 4-door Polestar 5 is expected to have torsional rigidity superior to that of a traditional two-seat sports, or supercar.

“We knew we wanted this car to be light-weight, we knew we wanted high quality and we knew we wanted it quickly,” says Pete Allen, Head of Polestar UK R&D. “This architecture delivers outstanding dynamic and safety attributes, with low investment technology applicable to high production volumes.”

Development of Polestar 5 is gathering speed, with worldwide 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. More details on Polestar 5 will continue to surface as the YouTube documentary series “Precept: From Concept to Car” details how the Polestar Precept evolves into the production car.

This Polestar is proposing a business combination with Gores Guggenheim, Inc. and if it goes ahead, should close in the first half of 2022.
