INTRODUCTION
The BMW M4 Convertible (F83) Competition 3.0, launched in 2016, was a significant upgrade to the original F83 M4 Convertible. It slotted in as the top-tier offering within the 4 Series Convertible range, distinguished by its more powerful engine and enhanced performance features. Based on the F30 3 Series platform (internally known as F30/F80 for sedan/coupe variants and F32/F82 for the 4 Series coupe/convertible), the F83 aimed to deliver a thrilling driving experience without sacrificing the comfort and luxury expected of a BMW. The “Competition” package further elevated the performance, making it a desirable choice for enthusiasts seeking a high-performance convertible.
Powertrain & Engine Architecture
At the heart of the M4 Convertible Competition 3.0 lies the S55B30A, a 3.0-liter inline-six engine. This engine, a derivative of the N55, was specifically designed for the M series and featured significant upgrades including a closed-deck engine block, forged crankshaft, and upgraded cooling system. The S55 utilizes direct fuel injection and a twin-turbocharger setup, delivering 450 horsepower at 7,000 rpm and 550 Nm (405.66 lb-ft) of torque between 1,850 and 5,500 rpm. The engine’s robust torque curve provides strong acceleration throughout the rev range. Paired with the engine is a 7-speed M Double Clutch Transmission (DCT) with Drivelogic. This dual-clutch transmission offers incredibly fast and precise gear changes, contributing to the car’s impressive performance. The DCT features multiple shift programs, allowing the driver to tailor the transmission’s behavior to their preferences and driving conditions.
Driving Characteristics
The M4 Convertible Competition 3.0 delivers a dynamic and engaging driving experience. The DCT transmission provides near-instantaneous shifts, allowing for rapid acceleration. The increased power output compared to the standard M4 Convertible is immediately noticeable, resulting in a 0-60 mph time of approximately 4.1 seconds. While the convertible body adds weight compared to the coupe, the chassis is well-tuned to minimize body roll and maintain a planted feel. The steering is precise and communicative, providing excellent feedback to the driver. The Competition package includes adaptive dampers, which allow the driver to adjust the suspension stiffness to suit their driving style and road conditions. Compared to the standard M4 Convertible, the Competition model feels more responsive and eager to accelerate, making it a more rewarding experience for performance-oriented drivers.
Equipment & Trim Levels
The M4 Convertible Competition 3.0 came generously equipped as standard. Interior features included leather upholstery, power-adjustable sport seats with memory function, a premium sound system, and a navigation system. Standard exterior features included M-specific aerodynamic enhancements, including a front splitter, side skirts, and a rear diffuser. Optional extras included carbon fiber trim, upgraded leather options, a head-up display, and a driver assistance package. The convertible top was a fully automatic, retractable hardtop, providing both open-air enjoyment and security when closed. The interior trim was typically finished in aluminum or carbon fiber accents, enhancing the sporty ambiance.
Chassis & Braking
The M4 Convertible Competition 3.0 features a sophisticated chassis designed to maximize handling performance. The front suspension utilizes an independent coil spring setup with aluminum components to reduce weight. The rear suspension employs an independent multi-link design, providing excellent wheel control and stability. Braking duties are handled by ventilated discs on all four wheels, with large calipers providing ample stopping power. The car is equipped with ABS (Anti-lock Braking System), Dynamic Stability Control (DSC), and other electronic aids to enhance safety and control. The Competition package included upgraded brakes with larger rotors and calipers for even more stopping power.
Market Reception & Comparison
The M4 Convertible Competition 3.0 was generally well-received by automotive critics. Reviewers praised its powerful engine, responsive handling, and luxurious interior. The DCT transmission was lauded for its speed and precision. However, some critics noted the added weight of the convertible body compared to the coupe, which slightly impacted handling agility. Compared to the standard M4 Convertible, the Competition model was considered a significant improvement, offering a more engaging and rewarding driving experience. Fuel economy, while not a primary concern for buyers in this segment, averaged around 27 US mpg combined. Reliability was generally good, although some owners reported minor issues with the electronic systems.
Legacy
The BMW M4 Convertible (F83) Competition 3.0 remains a desirable performance convertible in the used car market. The S55 engine is known for its durability and tunability, making it a popular choice for enthusiasts. While maintenance costs can be higher than those of more mainstream vehicles, the M4 Convertible Competition 3.0 offers a unique combination of performance, luxury, and open-air enjoyment. Its strong performance credentials and iconic status within the BMW M lineup ensure its continued appeal to driving enthusiasts for years to come. Well-maintained examples command a premium in the used car market, reflecting their desirability and performance capabilities.
