Polestar has presented a prototype of development that it will be a four-door grand tourer called the Polestar 5 in the Goodwood Festival of Speedrevealing more information about its electric powertrain, ahead of its launch in 2024. The two dual motors of which it consists take advantage of an 800-volt electrical system so that they are capable of producing 652 kW of power (884 hp), and offer a torque of 900Nm.
During the event, the Polestar 5 will climb the legendary Goodwood Hill twice a day in the “First Glance” group. The vehicle, scheduled to be unveiled in 2024, is the third of three new electric vehicles that Polestar will bring to market in the next three years, after the Polestar 3 and Polestar 4 electric SUVs.
The Polestar 5 is an evolution of the 2020 Precept concept, from which it inherits a sleek silhouette and most of its distinctive features. The prototype presented at Goodwood has received a small evolution with respect to the one revealed by the recently leaked sketches of the patent plans for the European Union presented to EUIPO. Polestar has added new stickers to the camo that hint at the lights and air intakes of the production car. Even so, this coverage creates dummy lights and air intakes that differ from those of the production model.
As for the drivetrain configuration that will animate this sports car, Polestar has revealed some interesting details. The first of these is that it will have an 800 volt system made up of dual electric motors. The combined power of both is 650 kW (884 hp) and are capable of producing a combined torque of at the output of these 900Nm. Polestar ensures the new rear-mounted motor will provide superior acceleration capability by working alongside the front electric motor. The power supply comes from a battery of 103 kWh capacity that can be charged to 80% in just 20 minutes thanks to its 800-volt architecture.
The presentation mentioned features in development such as the Bidirectional charging and V2G capabilities (vehicle to grid) to communicate with the electrical network, as well as a two-speed dual-clutch gearbox with kickout functionalthough the company did not explicitly say that the Polestar 5 will implement them in the final production model.
The propulsion system is being developed from Sweden and it is to be assumed that in the future it may be used in other models of the brand. According to Jörg Brandscheid, Chief Technology Officer and R&D Director at Polestar, “The new powertrain we are working on will set a new brand benchmark for our high-performance cars.”
The Polestar 5 platform is being developed in the UK where the team has had the opportunity to work with a new mechanical architecture that has allowed it to design and develop an exclusive welded aluminum chassis which gives the vehicle its dynamic properties and offers a great driving experience. The platform is similar to those used by low-volume performance vehicles, but Polestar has made mass production possible. The company announced that the architecture will offer torsional rigidity greater than that of a two-seater supercar, with a weight comparable to that of cars in smaller segments.
As Pete Allen, UK R&D Director for Polestar explains: “The Polestar 5 is well on its way to becoming a superb 4-door GT with everything Polestar stands for. The platform combines the performance of a limited-production vehicle with modern technological advances to create a lightweight, rigid sports chassis technology that can be mass-produced.”
Brandscheid says that the combination of strong electric motor engineering capabilities with advances in light-duty technology is resulting in “a model offering with impressive features.”
For Thomas Ingenlath, CEO of Polestar, “the Polestar 5 is a project that defines us as a company. Its progressive design and advanced engineering will shape the future of Polestar. The enormous talent of our professionals is what allows us to create electric vehicles that leave their mark.”
