Polestar 2 Single Motor Electric Vehicle Now Available in United States

Polestar, the premium electric performance car maker, today announced inbound availability of the all-electric Polestar 2 Long range Single motor fastback in the United States. Available to order online at Polestar.com, the single-motor Polestar 2 features an accessible starting price of $45,900, or as low as $33,400 after qualified federal and state incentives*.

In addition to being the lowest priced vehicle in the Polestar lineup, this latest model’s EPA estimated 270-mile range** is the brand’s longest, all while offering the same standard features as the high-performance dual-motor Polestar 2. This includes the world’s first infotainment system powered by Android Automotive OS with Google built-in, a premium vegan interior, and Polestar’s renowned chassis tuning.

Expanding the Polestar 2 model range in the United States represents another step in the company’s robust growth plans, including a global sales target of approximately 65,000 vehicles in 2022. In September 2021, the company announced its intention to list on the Nasdaq stock exchange through a business combination with Gores Guggenheim, Inc. (Nasdaq: GGPI, GGPIW and GGPIU).

“The single-motor Polestar 2 can be had for well under $35,000 in states like New Jersey, making it one of the most compelling offerings on the market,” said Gregor Hembrough, Head of Polestar North America. “All variants of the Polestar 2 exude the brand’s leadership in cutting-edge technology with the Google infotainment system, premium sustainable materials, and unparalled avant-garde design.”

“Plus” and “Pilot” option packs are both available on all Polestar 2 variants. The Plus Pack ($4,000), features a-new-for-2022 mechanical heat pump to extend range, a full-length panoramic glass roof, a 13-speaker Harman Kardon audio system, and WeaveTech vegan interior upholstery. The Pilot Pack ($3,200) offers enhanced safety and driver assistance features, including Pilot Assist , Adaptive Cruise Control (ACC), and Blind Spot Information System (BLIS^TM). With these combined technologies, the Pilot Pack aids drivers to safely alleviate stress in certain driving situations.

Additionally, all Polestar 2 owners receive Over-The-Air (OTA) updates that deliver enhancements directly to the vehicle, enabling even the oldest cars to run with the latest technology. Recent updates include the ability to schedule charging sessions, quicker DC charging enabled by battery preconditioning, and a Range Assistant app that includes an Eco Climate function.

As part of the brand’s digital-first retail model, Polestar 2 can be ordered online at https://www.polestar.com/us/polestar-2/configurator/ or with the help of Polestar Specialists at one of the brand’s retail locations.

Polestar currently has retail locations, – or Spaces – open in major markets across the US.

About Polestar

Polestar was established as a new, standalone Swedish premium electric vehicle manufacturer in 2017. Founded by Volvo Cars and Geely Holding, 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 fiber 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.

In the coming three years, Polestar plans to launch one new electric vehicle per year, starting with Polestar 3 in 2022 – 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.
