Polestar, Volvo Car Group’s performance brand, revealed its future as a new standalone electric performance brand. Polestar has confirmed the company’s first three models, a new purpose-built production facility in China and a new, customer-focussed route to market with all-inclusive subscription-based services that will set a new industry benchmark for performance car buyers.

Polestar will act as a technology spearhead for the Volvo Car Group, bringing new technology and performance attributes to market. At the same time, Polestar will benefit from technological and engineering synergies within Volvo Cars and significant economies of scale as a result. These synergies will allow Polestar to accelerate the design, development and building of its electrified performance cars.

The company's first car, Polestar 1, will start production in mid-2019 and form a halo for the future Polestar brand. The Polestar 1 is a two-door, 2+2 seater with an 'Electric Performance Hybrid' drivetrain. A maximum of 500 cars per year will be built. All cars will be offered on a subscription basis, with customers benefitting from the convenience of a single, all-inclusive payment that can be topped up by additional on-demand services if required."

Showcasing Polestar's technology spearhead role, the Polestar 1 is based upon Volvo's Scalable Platform Architecture (SPA) but approximately 50% is new and bespoke, created by Polestar's engineers. A further example of the technology spearhead role is an all-new double electric motor system driving both rear wheels, connected together by planetary gears. Producing 218hp, plus the support of an Integrated Starter Generator, the Polestar 1 in Pure mode, is a rear wheel drive Electric performance car with up to 150km of range. This distance ensures that many customers will only ever use the car in full electric mode.

For those needing increased range, or wanting to exploit the full performance attributes of the Polestar 1, the double electric rear motors combine with a Volvo Drive-E two-litre four-cylinder petrol engine, powering the front wheels. In Power mode, the Polestar 1 delivers a total of 600hp and 1,000Nm of torque."

When the driver enters the first corner in their Polestar 1, the car promises to differentiate itself from its electric car competitors. This is what Polestar defines as Progressive Performance. Polestar's experience of fitting Öhlins suspension to all its previous performance road cars has been harnessed, with Polestar 1 fitted with a state-of-the-art chassis, including the all-new Öhlins Continuously Controlled Electronic Suspension (CESi) - the world's first car to be fitted with this advanced chassis technology.

Each Öhlins shock absorber is fitted with a new electronic valve, installed for the first time on any road car in conjunction with Öhlins shock absorbers. The valve constantly monitors the driver inputs and road surface conditions, reacting in two milliseconds, to immediately change the ride characteristics to the prevailing demands. For the first time on an Öhlins suspension, the driver can also make changes to the suspension settings within the car, constantly able to tailor the chassis damping and ride quality to their own requirements."

Complementing the suspension technology is a powerful braking system to provide the driver with total confidence in all driving situations. Manufactured by Akebono, the 6-piston brake callipers and 400mm discs provide maximum stopping capability. Weight distribution of 48F:52R also ensures the car delivers class-leading handling."

The Polestar 1 also brings other new technologies to the market for the Group. Thanks to the double electric rear axle's planetary gears, torque vectoring features for the first time, separating the power from each of the electric rear motors to drive the car through corners, rather than convention traction control systems that brake the inner rear wheel, slowing the car in bends."

As another first for the Group, the major body parts of the Polestar 1 are made from carbon fibre. This lightweight material, more commonly found in supercars, gives the car three significant advantages. Firstly a substantial body weight reduction of 230kg by building in lighter Carbon Fibre. Secondly, an increase in torsional stiffness of 45%, from 22Nmm-2 to 32Nmm-2. And additionally, a lower centre of gravity. Reducing the weight of the upper body panels by using lightweight Carbon Fibre lowers the centre of gravity for the Polestar 1 and results in better handling, performance and drivability on an open and flowing road."
