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.
