How long will the 2018 Audi A8 last?

With proper maintenance, a 2018 Audi A8 can realistically provide 150,000 to 200,000 miles or 10-15 years of service. However, its long-term durability hinges on consistent and meticulous maintenance. Weaknesses tend to emerge with the air suspension system, which can require costly repairs as the vehicle ages. Electronic components, including the infotainment system and driver-assistance features, are also potential areas of concern. Regular fluid changes, timely replacement of wear items, and proactive attention to any warning signs are crucial for maximizing the A8's lifespan.
