The 650-kilowatt (872-hp), $200,000 (196,635 euro) full-electric roadster, which will be called the Polestar 6, will be the automaker's most powerful and most expensive model when it arrives in 2026.
The brand's most powerful and expensive model now is the Polestar 1, which offers more than 600 hp and starts at 155,000 euros. Meanwhile, the Polestar 3 premium large SUV, which will debut in October, is expected to start at 75,000 euros.
Polestar will build the hardtop convertible alongside the Polestar 5 electric luxury sedan in Chongqing, China.
The cars will share Polestar's new lightweight bonded-aluminum platform and an 800-volt electric architecture that in addition to providing nearly 900 hp of power will offer 900 newton meters of torque, 0 to 100 kph (62 mph) acceleration in 3.2 seconds, a top speed of 250 kph (155 mph) and an estimated range of more than 480 km (300 miles).
Polestar previewed what to expect from the Polestar 5, which is due in 2024, at the Goodwood Festival of Speed in England in June.
Like the Polestar 6, the Polestar 5 started as a concept, called the Precept, that evolved into the brand's future flagship grand tourer.
Polestar currently aligns its estimated starting prices with Porsche models. For instance, the Polestar 3's 75,000-euro base price is in line with the Porsche Cayenne, which starts at about 83,000 euros in Germany.
The Polestar 4 and Polestar 5, for which no official prices have been given, will align with the Porsche Macan and Porsche Panamera, which start at about 66,000 euros and 98,000 euros, respectively, in Germany.
The current 911 Turbo Cabriolet starts in about 212,000 euros in Porsche's home market.
