Batteries
The Polestar 1 has a total capacity of 34kWh arranged in three battery stacks (two packs). This allows the Polestar 1 for an electric range of 150 km (NEDC). Polestar claims, this would be the largest electric range for any hybrid available at this time (February 2018).
Power distribution
The Polestar 1 has a plug-in hybrid powertrain, the supercharged and turbocharged high-performance petrol in-line four-cylinder petrol engine drives the front wheels. Two electric motors drive the rear wheels. In addition to these electric motors the Polestar 1 is equipped with an Integrated Starter Generator (ISG). Combined with the electric motors are planetary gear sets. These planetary gear sets enable torque vectoring, a technology used in racing to bring both acceleration and stability through curves.
Design
Outside
Practically all parts of the Polestar 1 upper body, including doors, bonnet and boot-lid, are made of carbon fibre reinforced polymer (CFRP) for maximum stiffness, torsional rigidity and lightness. The Polestar 1 has a standard-fitted active rear spoiler delivering high-speed downforce on the rear axle. It automatically raises from its integrated flush position when the speed exceeds 100 km/h (62 mph) and is retracted when the speed is reduced below 70 km/h (43 mph). Polestar 1 comes with a fixed panoramic glass roof, stretching all the way from the top of the windscreen to the upper edge of the rear window. The interior features handcrafted leather detailing and a carbon fibre wing that stretches to the full height of the instrument panel. The Polestar 1 also comes with a Bowers & Wilkins high-end sound system. The tyre sizes are 275/30 R21 for the front and 295/30 R21 for the rear.

The Polestar 1 has double wishbone front suspension, connecting each wheel with two transverse links. This design enables the front suspension to counteract torque steer. Most suspension parts are made of aluminium. The rear suspension is an integral link design, with a transverse composite leaf spring. Polestar 1 is the first car with Öhlins Continuously Controlled Electronic Suspension (CESi). The CESi can be set to adapt instantly to road conditions and in accordance with the driver’s chosen setting. The front brakes, are specified by Polestar and manufactured by Akebono, six piston aluminium Mono block calipers on each front wheel are milled from one-piece. The calipers are coupled with 400x38mm ventilated and drilled discs.
