The Hyundai i20 has been in continuous production since 2008, evolving through three generations with steadily improving build quality and glass specification.
Earlier generations carry straightforward toughened rear glass, while newer i20s from the mid-2010s onwards increasingly feature green-tinted rear windows as standard — a subtle tint that reduces glare and UV transmission without affecting visibility.
The latest generation has introduced SmartSense ADAS systems on higher-spec variants, though rear-window replacement itself doesn't involve calibration (only windscreen replacement does). Rear glass remains toughened across all variants.
