The Polestar 5, the production version of the Precept concept that will be introduced in 2024, is going to use a bonded aluminium platform developed in-house by Polestar’s R&D team in Coventry, UK.
The fully electric performance four-door GT has been teased in the past but this is the first time we get to see its bespoke architecture. Pictures of the architecture also show parts of the Polestar 5’s body, including the sloping roofline and the sharp rear fenders.
The bonded aluminium structure is both lightweight and rigid, benefiting the efficiency, EV range, safety, and dynamics of the Polestar 5. While this type of platform is more commonly used for low volume vehicles, Polestar says they made it possible thanks to an entirely new manufacturing process that “develops both body and platform in unison, significantly reducing traditional lead times”. The bespoke platform will allow Polestar 5’s body-in-white (platform and body panels) to weigh less than that of cars in smaller segments, with a torsional rigidity superior to that of a traditional two-seat sportscar or supercar.
Pete Allen, Head of Polestar UK R&D, said: “We knew we wanted this car to be light-weight, we knew we wanted high quality and we knew we wanted it quickly. This architecture delivers outstanding dynamic and safety attributes, with low investment technology applicable to high production volumes.”

Polestar’s UK R&D team is based in the Midlands, with the current number of 280 engineers expected to grow to 500 employees in the coming months. Polestar’s CEO, Thomas Ingenlath refers to the team as one of Polestar’s greatest assets: “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.
Before the debut of the Polestar 5, the company will launch the upcoming Polestar 3 (SUV) and Polestar 4 (coupe-SUV), expanding its range next to the existing Polestar 2 sedan.
