Polestar Shows Off Its New Sports Sedan Naked

Polestar designs first chassis at UK shop

  • Polestar 5 coming in 2024

  • Bonded aluminum chassis will cut weight add rigidity


Polestar is showing off its latest model, giving us an almost X-ray view. It’s the bonded aluminum chassis that will underpin the Polestar 5 electric four-door coupe when that model arrives in 2024.

The new platform was designed and developed in-house by Polestar’s UK-based research and development crew in Coventry. It’s made to be lightweight and rigid, but Polestar says that it also offers environmental advantages.

Some of the environmental advantages come from the easy recycling of the aluminum, which can be reprocessed at vehicle end of life, as well as using bonding instead of welding processes to assemble the chassis, but it goes beyond that. The aluminum chassis is light, so light Polestar says it will undercut vehicles in smaller segments at the scales.

Lighter vehicles mean more efficiency, allowing smaller electric battery packs and longer range. They also help bolster dynamic responsiveness, making for a car that can be better to drive.

Polestar says the Polestar 5, the company’s first in-house platform, will have “torsional rigidity superior to that of a traditional two-seat sports- or supercar.” Polestar says that the bespoke platform will also allow a vehicle closer to the Precept concept car that inspired it.

“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.”

Before we see the Polestar 5, two crossovers are expected. The 4 in 2022, and the smaller Polestar 4 in 2023.
