ANCAP lists the Kia EV9 at 5 stars (2023) and the Polestar 4 at 5 stars (2025). ANCAP tested these in different years (2023 vs 2025).

Equipment few rivals have, on either carShowHide
Drivetrain
The Kia EV9 uses a Electric producing 160kW and 350Nm of torque, sent through a automatic to a RWD layout. It covers the 0-100km/h sprint in 8.2 seconds.
The Polestar 4 responds with a Electric Motor making 200kW and 343Nm, paired to a single-speed fixed gear driving the rear wheels. It gets to 100km/h in 7.1 seconds.
The Polestar 4 has the clear power advantage at 200kW vs 160kW. In the 0-100 sprint (manufacturer-claimed), the Polestar 4 is 1.1s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Battery: 76.1kWh (Kia EV9) vs 100kWh (Polestar 4), giving WLTP ranges of 519km and 620km. DC fast charging peaks at 240kW (Kia EV9) vs 200kW (Polestar 4).
Space & Comfort
The Kia EV9 measures 5,010mm long on a 3,100mm wheelbase, 170mm longer than the Polestar 4 at 4,840mm (2,999mm wheelbase). The longer wheelbase on the Kia EV9 generally means more rear legroom.
Boot space is 333L in the Kia EV9 and 526L in the Polestar 4, giving the Polestar 4 a 193L advantage. The Kia EV9 seats 7 vs 5.
For towing, the Polestar 4 leads with a 1,500kg braked capacity vs 900kg. That 600kg difference matters if you regularly hitch up.
Neither U-turns in one sweep on a 7 m local street (both need a three-point turn); the Polestar 4's turning circle is 0.4 m tighter, 11.6 m against 12.0 m kerb to kerb. The street estimate is indicative, worked from the published turning circles.
Cost to own
At 15,000 km a year, electricity for the Kia EV9 costs about $1,042 a year (21.7 kWh/100km) and electricity for the Polestar 4 about $806 a year (16.8 kWh/100km), at $1.90 a litre and 32c a kWh. That is $236 a year less for the Polestar 4.
Warranty: 7 years / Unlimited (Kia EV9) and 5 years / Unlimited (Polestar 4).
Where each one leads
The Kia EV9: the longer warranty (7 years against 5).
The Polestar 4: the lower starting price ($78,500 against $97,000), more power (200kW against 160kW), the bigger boot with the seats up (526L against 333L), the higher braked towing limit (1,500kg against 900kg) and lower fuel or energy costs on our assumptions ($806 a year against $1,042).

Polestar 4 scores higher, 75 vs 67
The Polestar 4 scores 75 to the Kia EV9's 67 on the CarSorted Score, and leads 7 of the 11 spec rows that separate them, at the lower price.
