To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Countryman SE. But it costs extra on the Polestar 4.
The Countryman SE has standard Assist eCall, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in or send emergency personnel to the scene if any airbags deploy. The Polestar 4 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Countryman SE and the Polestar 4 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
