Permanent-magnet motors and inverters sing in kilohertz bands, while reduction gears add tonal teeth signatures. Comfort-focused tuning blends micro-geometry polishing, optimal switching strategies, and sound design that emphasizes softer harmonics. Add structured barriers around the e-axle, and the result is presence without piercing. Passengers perceive purpose and power, yet the soundtrack fades into a gentle, confident hush that soothes rather than startles.
Hydraulic bushings with frequency-dependent damping isolate harsh impulses without blurring steering precision. By decoupling the e-axle and battery cradle from the cabin at targeted frequencies, engineers erase resonant peaks that can fatigue ears and minds. The car retains crisp responses, yet impacts arrive rounded, filtered, and politely brief. It feels like riding a soft cloud that still remembers the road well enough to keep you secure.
Tiny gaps become megaphones at highway speed. Multi-lip door seals, acoustic grommets for high-voltage looms, and double-bulkhead strategies block airborne leaks while foam-in-place fillers tame structure-borne flanking. Even drainage paths get labyrinths that slow pressure waves. The outcome is conversational clarity at a whisper, making long journeys less tiring and letting subtle details in music, podcasts, and navigation prompts shine without raising volume.
