In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Kona Electric are reminded to check the back seat if they opened the rear door before starting out. The Polestar 2 doesn’t offer a back seat reminder.
The Kona Electric has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Polestar 2’s blind spot costs extra.
To help make backing out of a parking space safer, the Kona Electric has standard Rear Cross-Traffic Collision Warning and Rear Cross-Traffic Collision-Avoidance Assist automatically engages the brakes to help avoid a collision. Polestar charges extra for Cross Traffic Alert on the Polestar 2.
Both the Kona Electric and the Polestar 2 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors and available rear parking sensors.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the Kona Electric the rating of “Top Safety Pick” for 2017, a rating granted to only 234 vehicles tested by the IIHS. The Polestar 2 has not been tested, yet.
