Rear Window Architecture and Embedded Electronics on the Polestar 2
The fastback profile of the Polestar 2 positions the rear back glass at an exceptionally low, aerodynamic rake directly fixed to the steel liftback frame. Because there is no rear wiper assembly or washer nozzle penetrating the pane, the glass relies entirely on an integrated electric heating grid to evaporate standing rainwater, road spray, and winter slush. When activated via the center infotainment display, the software circuit simultaneously powers this rear grid and the heating elements inside the frameless exterior side-view mirrors.
Woven directly into the tempered safety glass alongside the heating lines is an embedded radio antenna array. Polestar specifically restricts the use of metallic or metallized aftermarket window tint films across this rear pane, as the conductive metals degrade radio frequency reception through that printed grid. The entire glass perimeter features a high-gloss black encapsulation that aligns flush beneath the upper tailgate aerodynamic spoiler, while the interior plastic tailgate garnish panels conceal the wiring pigtails that supply power to the heating lines and route the antenna leads into the vehicle harness.
Trim Consistency Across 2025 and 2026 Builds
Whether dealing with a base single-motor build or an upgraded dual-motor configuration with performance hardware, the tailgate stamping and back glass profile remain completely uniform across these model years. I handle every replacement myself directly on-site at your home or workplace across Toronto and the GTA, ensuring the interior liftgate trim panels and wiring harnesses are reassembled cleanly without disturbing the rear headliner.
| Trim Level (2025–2026) | Glass Construction | Defroster & Antenna Grid | Wiper Through-Hole |
|---|---|---|---|
| Standard Range Single Motor | Tempered solar safety glass | Integrated grid; mirror-linked heating | None |
| Long Range Single Motor | Tempered solar safety glass | Integrated grid; mirror-linked heating | None |
| Long Range Dual Motor | Tempered solar safety glass | Integrated grid; mirror-linked heating | None |
| Performance Pack | Tempered solar safety glass | Integrated grid; mirror-linked heating | None |
Managing Visibility and Structural Nuances
A frequent observation among Polestar 2 drivers is restricted rear visibility. The high rear beltline, thick C-pillars, and rear seat headrests already narrow the optical window, and the shallow rake prevents road mist from sliding off the surface when idling or driving at lower speeds. Because the glass lacks a mechanical wiper, full functional continuity of every run in the defroster element is critical to keeping the center rearview mirror usable during wet weather.
Unlike the acoustic laminated glass found on the windshield or the heavy laminated panoramic glass roof overhead, the liftback uses automotive tempered glass designed to fracture safely under severe impact. Replacing this pane requires unhooking the defroster solder joints and antenna terminals hidden behind the tailgate header and side trim pieces, keeping the factory electrical connectors intact without straining the tailgate wiring loom.
