# 2016-2020 BMW M4 Competition Convertible The M4 Competition Convertible represents BMW's high-performance open-air sports car, powered by a twin-turbocharged 3.0-liter inline-six producing 444 horsepower (19 more than standard). It sprints 0-60 mph in roughly 4 seconds. Reviewers praise its explosive acceleration and razor-sharp handling, though many lament the polarizing retractable hardtop's weight penalty (nearly 500 pounds versus the coupe). The exhaust note disappoints purists compared to naturally-aspirated predecessors. **Famous for:** Controversial styling and notoriously tail-happy dynamics that reward skilled drivers but punish overconfidence. **Ideal for:** Driving enthusiasts who prioritize performance over practicality and want open-air thrills with everyday usability. The retractable hardtop offers better security and year-round versatility than fabric alternatives. **Considerations:** Substantial depreciation makes used examples attractive, though maintenance costs remain premium-brand expensive.
The M4 Competition Convertible requires premium fuel and expensive synthetic oil changes. High-performance tires wear quickly ($1,500+ per set). Common issues include carbon buildup requiring walnut blasting ($600-800). Convertible top mechanisms can fail ($2,000-4,000). Insurance costs are significantly above average due to high-performance classification. Dealer maintenance is costly; independent specialists recommended.
