Does the 2025 Lexus IS receive major chassis and suspension overhaul?
The 2025 Lexus IS retains the GA-T platform launched in 2021; improvements focus on suspension calibration and sound isolation. Lexus refines Adaptive Damping System tuning to reduce chassis roll on bumpy roads at 110 km/h—recurring complaint from 2021–2024 owners. Laminated windshield and reinforced side panels reduce highway rolling noise by 1–2 dB(A). For Canadian drivers prioritizing smooth urban ride in Montréal, these targeted improvements deliver noticeably refined experience without mechanical revolution.
