# 2018-2025 BMW M850i xDrive Coupe The M850i xDrive revived BMW's flagship 8 Series as a high-tech grand tourer blending performance and luxury. Powered by a twin-turbo 4.4L V8 producing 523 hp, it rockets to 60 mph in 3.6 seconds while offering all-wheel-drive stability and a refined ride. Reviewers praise its effortless power, composed handling, and opulent cabin featuring cutting-edge technology and premium materials. However, some enthusiasts critique its hefty 4,500-pound curb weight, somewhat isolated driving feel compared to sportier rivals, and polarizing styling. The M850i is famous for its dramatic presence and impressive autobahn-crushing capability but remains less track-focused than competitors like the Porsche 911. **Ideal for:** Affluent buyers seeking a comfortable, daily-drivable GT with serious performance credentials for long highway journeys and weekend getaways—not hardcore track enthusiasts.
The M850i requires premium fuel and synthetic oil changes. High-performance run-flat tires wear quickly ($2,000+ per set). Carbon-ceramic brakes are a costly option to replace ($15,000+). Turbocharged V8 maintenance is expensive. Insurance rates are high due to performance classification and repair costs. Generally reliable but expect premium maintenance expenses typical of luxury performance vehicles.
