# 2017-2025 BMW X3 M40i The X3 M40i is BMW's performance-oriented compact luxury SUV, slotting below the full-fat X3 M. Powered by a turbocharged 3.0-liter inline-six producing 355-382 horsepower (depending on model year), it delivers 0-60 mph in around 4.4 seconds while maintaining everyday practicality. Reviewers praise its engaging handling, punchy engine, and refined interior, though some criticize its firm ride and complexity. It's famous for offering M-car thrills without the extreme edge, making it a sweet spot in BMW's lineup. The X3 M40i suits driving enthusiasts who need family-friendly versatility—parents wanting spirited performance for daily commutes and weekend drives without sacrificing cargo space or all-weather capability. It's ideal for those seeking a single vehicle that balances sportiness with SUV practicality, though its premium pricing and fuel consumption may deter budget-conscious buyers.
The X3 M40i requires premium fuel and costly synthetic oil changes. The turbocharged inline-six engine is generally reliable but may need expensive carbon cleaning. Run-flat tires wear quickly and cost more to replace. Insurance rates are higher due to performance classification. Maintenance costs exceed non-M models, with brake and suspension components particularly expensive.
