Lightweight forged wheels leverage Zhigu's forging technology to achieve industry-leading weights, with 18x8J rims weighing 7.2kg (25% lighter than cast). This is achieved through hollow spoke geometry, 2.5mm thin-wall forging, and flow forming (improving material ductility by 15%). Benefits include 0.3-0.5s faster 0-100km/h acceleration, 1-2m shorter braking distance, 5-8% better cornering grip, and 2-3% improved fuel efficiency. Materials include 6061-T6/7075-T6 aluminum and magnesium alloys. Testing meets JWL/VIA standards, including high-speed stability testing at 300km/h (vibration amplitude <0.1mm).
