The Volvo Polestar Engineered trim level typically adds over 10 horsepower to the T8 eAWD powertrain. This trim level focuses on racetrack-ready handling, with powerful upgrades like a tuned chassis, high-performance Brembo brakes, advanced Öhlins suspension, and specialized wheels to provide a refined yet agile ride. The Polestar optimization software, though, typically adds around 25 horsepower to select gas-powered Volvo models.
