Maintenance costs for an Audi S5 are typically higher than standard sedans, with an average annual cost between $900 and $1,200, as it requires specialized synthetic oil, high-performance brake components, and specific Quattro system fluid changes; however, the 2026 model often includes "Audi Signature Care" covering scheduled maintenance for the first three years. 对考虑购买 Audi S5 的买家来说,这项信息真正重要的地方在于它会影响通勤、家庭使用、长途驾驶或后期拥车成本。不要只把它当成配置数字来看,而要看它能不能让日常用车更轻松、更实用。
