I have a closely related vehicle, Volvo's 402 hp dual-motor XC40 EV with about 210 miles EPA range. This SUV shares its architecture and performance with the Polestar 2, though the Polestar gets better range due to better aerodynamics. We've taken several 1000-mile road trips in the Volvo and love it compared to our previous Model 3. Despite the Model 3's greater range, we always take the Volvo due to its greater comfort, safety, and amenities. On a 450-mile road trip, the XC40 requires one more charging stop than our Model 3 did. Not a bad tradeoff for a better car.
The Polestar also has great driver ADAS and safety features that are useful everyday. BTW Volvo's C40 fastback is sort of halfway between the Polestar 2 and the XC40 in case that's of interest.
In summary, I'd get the dual motor variant of the Polestar 2 without hesitation. It'll be a great road-trip car in most areas of the country, though it would be challenging to visit large remote national parks like Yellowstone, Glacier, etc due to lack of charging stations within the park. If you are an Android phone user, you'll love the Polestar car's native Google Assistant, Google Maps and Nav, and other familiar tools. You can actually control your smarthome from the car using voice control just as you would from your phone or other Google Home device. Or ask the car any question you'd ask Google - not just a limited list of commands to control the car.
The Polestar 2 has AAOS/GAS's excellent road-trip planning functionality built in to Google Navigation.
Other than opting for the dual-motor version, I'd skip the performance suspension option as I've heard that the ride is harsher.
After living with the Volvo for sixteen months, I'm looking forward to October's public unveiling of the Polestar 3, a larger SUV with lidar and greater battery capacity. This is the car I'm still considering against my currently confirmed reservation for an Air GT.
