Polestar’s bonded aluminium technology could reduce both weight and the cost of EV manufacturing.
Composites and bonded aluminium structures are crucial in reducing the weight of EV’s.
Rumours suggest that the Polestar Precept Concept car is the vehicle upon which Polestar 5’s design will be based.
Polestar, the Swedish electric vehicle manufacturer, has announced that the next addition to its model lineup, the Polestar 5, will consist of a single all-aluminium body and platform.
According to the automaker, the design choices and techniques implemented in the development of the 4-door GT promise to reduce the overall weight of the car while offering increased torsional rigidity, surpassing that of traditional two-seat sports cars and supercars.
Composites and bonded aluminium structures are crucial in reducing the weight of EV’s.
Due to the inherent weight of the battery packs required for most electric vehicles, many EV’s often weigh considerably more than their equivalent petrol-powered counterparts. The Polestar 5’s bonded aluminium platform, however, could be the perfect workaround to close the gap. Pete Allen, Head of Polestar UK R&D said, “We knew we wanted this car to be lightweight, we knew we wanted high quality, and we knew we wanted it quickly.”

The decision to produce a complete body and platform instead of individual segments results in a lighter frame and makes the production process notably easier. Manufacturing a vehicle based on an all-aluminium platform would be time-consuming and costly, however, Polestar’s UK-based R&D has managed to streamline and improve this production process. As a result of the technological breakthrough in the car’s production process, the team has produced an end product that closely mirrors its Polestar Precept concept car. Polestar’s UK R&D department plans to expand in the coming months.
