About Polestar

Polestar was established as a new, standalone Swedish premium electric vehicle manufacturer in 2017. Founded by Volvo Car AB (publ) (together with its subsidiaries, “Volvo Cars”) and Zhejiang Geely Holding Group Co., Ltd (“Geely”), Polestar enjoys specific technological and engineering synergies with Volvo Cars and benefits from significant economies of scale as a result.

Polestar is headquartered in Gothenburg, Sweden, and its vehicles are currently available and on the road in markets across Europe, North America, China and Asia Pacific. By 2023, the company plans that its cars will be available in an aggregate of 30 markets. Polestar cars are currently manufactured in two facilities in China, with additional future manufacturing planned in the USA.

In September 2021, Polestar announced its intention to list as a public company on the Nasdaq in a business combination agreement with Gores Guggenheim, Inc. Full information on this definitive agreement can be found here.

Polestar has produced two electric performance cars. The Polestar 1 was built between 2019 and 2021 as a low-volume electric performance hybrid GT with a carbon fibre body, 609 hp, 1,000 Nm and an electric-only range of 124 km (WLTP) – the longest of any hybrid car in the world.

The Polestar 2 electric performance fastback is the company’s first fully electric, high volume car. The Polestar 2 model range includes three variants with a combination of long- and standard range batteries as large as 78 kWh, and dual- and single-motor powertrains with as much as 300 kW / 408 hp and 660 Nm.

From 2022, Polestar plans to launch one new electric vehicle per year, starting with Polestar 3 – the company’s first electric performance SUV. Polestar 4 is expected to follow in 2023, a smaller electric performance SUV coupe.

In 2024, the Polestar 5 electric performance 4-door GT is planned to be launched as the production evolution of Polestar Precept – the manifesto concept car that Polestar released in 2020 that showcases the brand’s future vision in terms of design, technology, and sustainability. As the company seeks to reduce its climate impact with every new model, Polestar aims to produce a truly climate-neutral car by 2030.

In early March 2022, Polestar revealed its second concept car, the Polestar O₂ electric performance roadster. Polestar O₂ builds on the design, technology and sustainability ambitions laid out by Precept and showcases the brand’s vision for future sports cars. The hard-top convertible presents an evolution of the unique design language first shown by Precept and emphasizes a dynamic driving experience. The concept further develops the focus on sustainability and technology, aiming towards greater circularity.
