New 2024 Polestar 5 arrives at Goodwood with 874bhp
UK-developed Porsche Taycan rival to get ultra-stiff platform and new battery technology

The Polestar 5 has made its debut at the Goodwood Festival of Speed, and the Swedish firm has revealed technical and powertrain information for the upcoming production model. 

While development of the car's powertrain is still ongoing, Polestar has confirmed it is aiming for a power output of 874bhp with 663lb ft of torque.

It makes use of two electric motors attached to the front and rear, connected to 800V architecture. 

Polestar CEO Thomas Ingenlath has described the four-door grand tourer, which will go on sale in 2024, as a “company defining project”.

“Its progressive design and advanced engineering set the tone for Polestar’s future,” said Ingelath. “We have great talent on board enabling us to create truly iconic EVs.”

The 5 is an evolution of 2020's imposing Precept concept. As such, it will arrive in dealerships with familiar coupé-esque proportions and a lengthy wheelbase that line it up as a rival to the Mercedes-Benz EQS.

Only the concept's most outlandish features – its heavily accentuated side creases, ultra-slim digital wing mirrors, reverse-opening rear doors and oversized alloy wheels – look to have been casualties of the homologation process.

The firm has also unveiled the Polestar 2 BST Edition 270: the new high-performance, limited-edition version of the popular 2 electric fastback.

Speaking about the launch, Polestar CEO Thomas Ingenlath said: “Goodwood is our favourite place to show our cars in an enthusiast environment.

"This year, we're thrilled to showcase the Polestar 5 going up the hill. Our UK R&D team is doing an amazing job developing the car, and we're proud to be able to highlight their hard work at this early stage.

A full production-spec unveiling of the 5 isn't anticipated until late next year, but Polestar has already confirmed its saloon flagship will get “supercar levels” of body stiffness from an all-new platform being developed at a new engineering base in Warwickshire.

The 5 is the first Polestar car to be developed in the UK, as well as the first “developed by Polestar for Polestar”, rather than derived from a Volvo base, according to vehicle engineering director Steve Swift, speaking to Autocar earlier this year.

The 5’s body is constructed chiefly from bonded aluminium, with other sections made from hot-formed, cold-formed, die-cast and extruded aluminium. It’s this bonded aluminium construction that affords the car “supercar levels of torsional stiffness, which is fundamental to class-leading ride and handling dynamics”, said Polestar UK chief engineer Dave Kane.

UK R&D boss Pete Allen added that a goal for the 5 is to “deliver best-in-class levels of dynamics, and that starts with the structure”. To that end, the 5’s body offers “carbonfibre levels of torsional stiffness, like a two-door sports model”

Discussions are under way to establish exactly how to tune the 5’s stiff underpinnings to give it its dynamic character. “It’s still to be confirmed where it sits,” said Swift. “We’re looking for sophistication, rather than to take a Volvo and make it handle [like a Polestar].

“If you have a vehicle that rides well and is relatively isolated from road noise and then you get the handling right, you will appeal to those who love driving and also those who just like driving the car without articulating it.”

The Porsche Taycan is an obvious rival to the 5, and Polestar is understood to have one at its MIRA facility for benchmarking purposes. However, the Chinese-Swedish manufacturer wants to create a car with more everyday compliance and a rounded edge, rather than chasing truly sports car-like handling.

“It needs to be engaging but also comfortable,” said Swift. “We can push the car in a dynamic direction or a comfort direction without totally sacrificing one or the other.

Further developments include motorsport-derived underbody aerodynamics and a slippery body shape. Polestar isn’t yet discussing the powertrain and battery details of the 5 – prototype testing of which is already under way in the UK and in the Arctic Circle – but performance levels are expected to be prodigious given its range-topping position in the Polestar line-up. However, Swift disclosed that there’s some “interesting IP [intellectual property]” in the battery technology.

Polestar engineers have managed to maintain the look of the Precept concept car through to production.

Allen said they look “pretty much identical”, adding: “We use our ability to deliver cars as close as we possibly can to [Polestar CEO and designer] Thomas Ingenlath’s designs inside and out.”

To that end, the large panoramic roof remains, as do the long wheelbase and low roof height.

“It’s an extremely low car [for an electric car],” said Allen. “Not as low as an internal combustion engine car but close, and they don’t have batteries underneath. That has been a particular challenge.

Much of the engineering work on the 5 is being done with future Polestar products in mind.

There’s “a lot of scalability” in the new platform, said Swift. “You start with a car first, then look at the products in other spaces, then how many of those spaces we can play in while designing it once. It’s part of the future, definitely.”
