# 2016-2018 BMW X4 M40i The BMW X4 M40i represents BMW's performance-oriented take on the controversial "coupe-SUV" segment. Powered by a turbocharged 3.0-liter inline-six producing 355 horsepower, it delivers genuine M Performance driving dynamics with 0-60 mph in 4.7 seconds. Reviewers praise its sharp handling, powerful engine, and luxurious interior, though criticize its compromised rear headroom and cargo space compared to the standard X3. The sloping roofline prioritizes style over practicality—a polarizing design choice that defines the model. It's infamous for questionable styling and the "answer to a question nobody asked" label, yet appeals to driving enthusiasts wanting sportiness without sacrificing AWD capability. **Best suited for:** Empty-nesters and couples prioritizing performance and distinctive styling over maximum utility, who occasionally need AWD capability but rarely carry rear passengers.
The 2016-2018 BMW X4 M40i requires premium fuel and expensive synthetic oil changes. Common issues include water pump failures ($1,500-$2,000) and oil leaks from valve cover gaskets. Insurance runs high due to performance classification and repair costs. BMW's maintenance program may cover some costs if still active. Expect $1,500+ annual maintenance beyond warranty.
