Polestar 5 to Feature New All-Aluminum Architecture

Polestar is going aluminum for its all-new platform that will underpin its upcoming Polestar 5 performance sedan.

The new bespoke platform, developed in-house by Polestar’s U.K. R&D team in Coventry, England, will use bonded aluminum to cut weight while still offering strong rigidity, the battery-electric-vehicle maker says. Although the automaker doesn’t release specifics, it says the car will weigh less than vehicles that are smaller in size.

“We knew we wanted this car to be lightweight, 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.”

The Polestar 5, based on the automaker’s Precept concept car, also will use an innovative manufacturing process that will allow both the body and platform to be built simultaneously, significantly reducing manufacturing time, Polestar says.

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

The Polestar 5 reportedly is to debut in 2024 and be targeted against the likes of the Tesla Model S and Porsche Panamera. Power is expected to total more than 800 hp combined from its front and rear motors, and range is likely to exceed 300 miles (483 km). 

Production is expected to take place both in the U.S., at Volvo’s South Carolina plant, and in Chengdu, China.
