Polestar 4 — Research File (September 2026)
What the car is
Polestar's coupe-SUV (4.84 m) on Geely's SEA platform — the car that deleted the rear window and replaced it with a camera-fed digital mirror. Launched 2023 (China), 2024 in Europe/US; built in Hangzhou, plus Busan (South Korea) from 2025 for US-bound cars. Powertrains: Long Range Single Motor (200 kW/272 hp RWD, 0–60 6.9 s, ~300 mi EPA est.); Long Range Dual Motor (400 kW/544 hp, 3.7–3.9 s, 280 mi EPA / 373 mi WLTP). 100 kWh battery, 200 kW DC (10–80% in 30 min), heat pump, 11 kW AC (22 kW optional in some markets), V2L on newer builds. 15.4-inch Android Automotive screen, electrochromic panoramic roof option. Pricing Sept 2026: US $56,400 (single) / $62,900 (dual); Germany €69,900 (dual); France €69,800 (dual); UK £63,750 (dual, evkx.net, Aug 2026); China 398,000 yuan (dual). Polestar is leaving the US market after the 2026 model year (Autoblog, July 2026) — a major resale/support flag for American buyers.
Social-first owner evidence
Facebook groups: no dedicated Polestar 4 group surfaced via public-group search (Sept 2026) — disclosed gap. Rich owner-forum/press evidence:
- torquenews.com (owner group reports): owners "in love, quirks and all" — but the quirk list is long: no washer-fluid level sensor ("carry a bottle of water"), trunk doesn't always open, lane assist resets itself daily, wireless charger has no lip (phone slides under acceleration), ambient light strip reflects into the digital mirror at night, exterior temp sensor reads wrong in sun, washer bottle "in the worst place to fill".
- torquenews.com (3-week owner, ex-XC90): praise for comfort and dynamics; gripes — early software bugs, camera-only rear view, missing battery preconditioning on route planning, Pilot Assist slow to react.
- InsideEVs: the camera mirror is "fine" in daylight; at night there's glare, in rain/snow it's blurry, depth perception in parking lots is poor. Trunk is only 18.6 cu ft (Model Y: 30+).
- The Drive (2026 review, 7/10): "Polestar nailed the dynamics of a budget Porsche, but the lack of a rear window was a gamble." Steering "Porsche-worthy", composed on broken pavement.
- InsideEVs (2026): "probably Polestar's best car yet"; best-selling Polestar in Germany; global sales +36% in first 9 months of 2026. US downsides: tech hangups "fixable with software", inconsistent DC fast-charging performance, no NACS port (CCS + adapter), Model Y undercuts by ~$11k, Optiq by ~$5k.
- Reddit/forum flavor (via torquenews aggregation): "a work of art" with "double-vented comfort"; handling and torque delivery praised.
Reliability record
No powertrain or battery pattern failures documented — the SEA platform is proven at volume (Zeekr 001 shares the line). Complaints cluster on software, sensors, and ergonomic cost-cutting (washer sensor, charger lip, mirror reflections). Too new for long-term data; the hardware underneath looks sound.
Support reality
Polestar's brand situation is the support story: US exit after 2026 MY raises parts, software-update and warranty-honoring questions for American owners (Polestar says it will support cars — treat as company claim). Europe/China: normal Polestar/Volvo-adjacent service network; 2026 Korean-built cars diversify supply. Standard warranty terms vary by market — UNVERIFIED in detail.
Hype flags
"No rear window" is genuine design differentiation, not pure hype — but Polestar's claim the camera is "superior" is disputed by nearly every reviewer in rain/night conditions. The US-exit news broke mid-2026; some US coverage still lists it as a current buy without the caveat — flagged.

Sweet-spot year: 2025 — launch software matured, Busan-built US cars, before the US-exit resale hit. Years to avoid: 2024 launch cars (peak software bugs); in the US, any year if you plan to resell — the market exit will punish residuals.
