Polestar, the electric performance car brand, has revealed its new slick-looking convertible concept car that redefines sports roadsters for the electric age. The company has named it the Polestar O₂ and the hard-top convertible is Polestar’s vision of open-top performance and a thrilling driving experience, with all the benefits of electric mobility.
Thomas Ingenlath, Polestar CEO, said: “Polestar O₂ is the hero car for our brand. It opens the door to our secret chamber of future potential. This is a taste of what we can design and engineer with the talent and technology we have in-house.
“It looks incredible and being able to lower the roof and not hear an engine promises a superb sensation.”
Currently, there are few electric convertibles available. Last year AC Cars announced its new AC Cobra Series 4–electric sports car which combines classy looks, heritage and performance in a stunning zero-emissions package. MG also showed their futuristic-looking Cyberster concept car last year at the Shanghai Auto Show.
The new Polestar O₂ truly pushes the boundaries of what’s possible with a zero-emissions roadster. The driving experience in the Polestar O₂ is designed to be lively, light and full of confidence. Predictability and playfulness are core to exciting its spirited driving.
Tight body control, high rigidity and intuitive dynamics are inherent benefits of the bespoke bonded aluminium platform which is adapted from the Polestar 5, developed in-house by Polestar’s R&D team in the UK.
Maximilian Missoni, Polestar’s Head of Design, said: “Polestar O₂ is our vision of a new era for sports cars. By mixing the joy of open-top driving with the purity of electric mobility, it unlocks a new mix of emotions in a car.
“But as with all our cars, we are about more than just straight line sprints. It’s when you turn the steering wheel that the true fun begins.”
The high quality and rigidity of the bonded aluminium platform are geared towards heightened dynamic response. Handling dynamics are taut thanks also to small roll angles and high roll damping, and the agile, direct steering feel is linear, with great steering torque build-up.
Clearly related to the Polestar Precept concept car but with its own distinct character, the look of Polestar O₂ shows how Polestar’s evolving design language can be adapted to different body styles with a strong family resemblance.
The low and wide body with an assertive stance, compact 2+2 cabin design, minimal overhangs and a long wheelbase, embody classic sports car proportions but with a modern, electric feel.
Missoni added: “This car is a meeting point between technology and art, between precision and sculpture, with a determined but not aggressive stance.”
Aerodynamics are manipulated to maximise range thanks to disguised design features like integrated ducts that improve laminar airflow over the wheels and body sides. Plus, the rear lights function as air blades to reduce turbulence behind the car.
Sustainability and Technology
Polestar O₂ also showcases advances in sustainability and technology. A new thermoplastic mono-material features extensively in the interior. The term “mono-material” describes the use of a single base material to manufacture different components.
In Polestar O₂, recycled polyester is the sole material used for all the soft components of the interior using foam, adhesive, 3D knit fibres and non-woven lamination. This simplifies recycling and is a significant step towards greater circularity while also reducing weight, for greater efficiency, and waste.
Polestar sustainability teams believe that materials should be recycled, not downcycled. In Polestar O₂, they have integrated a new method of controlling recycled content and improving the circularity of metal components. Different grades of aluminium are used throughout the chassis to help deliver a thrilling driving experience.
These different grades are labelled, allowing them to be recycled more effectively and for their properties to be retained. High-grade aluminium remains high grade, while other grades maintain their varied characteristics, allowing for greater material efficiency and a lower requirement for virgin aluminium.
In a world increasingly driven by social media, the Polestar O₂ features an autonomous cinematic drone integrated behind the rear seats. Developed in collaboration with Aerofugia’s consumer electronics brand Hoco Flow, the concept drone can be deployed while the car is moving, to record the perfect driving sequence.
Polestar engineers have developed a specialised aerofoil that raises behind the rear seats to create a calm area of negative pressure that allows the drone to take off when the car is on the move.
The drone operates autonomously, automatically following the car at speeds up to 576mph (90kph) and the driver can choose between an atmospheric sequence, ideal for a coastline cruise, or a more action-filled sequence with a sportier expression.
After filming, the drone can autonomously return to the car. Video clips can be edited and shared directly from the 15-inch centre display when the car is parked.
Missoni concluded: “We wanted to emphasise the experience you can have with a car like the Polestar O₂ in new and unusual ways. Integrating an autonomous cinematic drone was something that allowed us to push the boundaries on the innovation front.
“Not needing to stop and off-load the drone before filming, but rather deploying it at speed, is a key benefit to this innovative design.”
Polestar O₂ continues the strong foundations laid by Polestar Precept as a vision of the company’s future design, technology and sustainability ambitions. Polestar plans to launch three new cars, including the Polestar 3 electric sports utility vehicle (SUV), over the coming three years, starting in 2022, each of which has the potential to gradually realise some of the ideas presented by these concept cars.
