INTRODUCTION
The BMW M4 Convertible (F83) Competition 3.0, launched in 2016, built upon the foundation of the standard F83 M4 Convertible, introduced in 2014. It represented a mid-cycle refresh and performance upgrade, incorporating lessons learned from the initial M4 models. The Competition package addressed some criticisms of the original M4’s engine responsiveness and overall driving feel. The F83 generation, part of the broader F30 3 Series lineage, aimed to blend the performance of the M3/M4 with the open-air enjoyment of a convertible. The Competition variant specifically targeted enthusiasts seeking a more focused and engaging driving experience.
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 is a significant departure from naturally aspirated BMW engines of the past, utilizing a twin-turbocharged setup to deliver substantial power and torque. The S55 engine features direct fuel injection, ensuring precise fuel delivery and optimized combustion. The valvetrain employs double-VANOS (variable valve timing) and double-VANOS (variable valve lift) technology, allowing for optimized engine performance across the rev range. The Competition model received revisions to the engine’s cooling system and oil supply to improve thermal management during sustained high-performance driving. The standard transmission for the Competition model was a 6-speed manual, although a 7-speed M Double Clutch Transmission (M DCT) with paddle shifters was also available as an option. The M DCT offered faster shift times and launch control functionality.
Driving Characteristics
The M4 Convertible Competition 3.0 delivers a noticeably more aggressive driving experience compared to the standard M4 Convertible. The increased power output, combined with the optimized engine mapping, results in quicker acceleration and a more responsive throttle. The manual transmission provides a direct connection to the engine, while the M DCT offers seamless and lightning-fast gear changes. The suspension, tuned specifically for the M4, provides excellent body control and minimizes roll during cornering. The steering is precise and communicative, offering ample feedback to the driver. While the convertible top adds some weight compared to the coupe, the M4 Competition 3.0 still feels remarkably agile and balanced. The exhaust note is particularly aggressive, enhancing the overall driving experience.
Equipment & Trim Levels
The M4 Convertible Competition 3.0 came standard with a comprehensive list of features, including leather upholstery, power-adjustable seats with memory function, a premium sound system, and a navigation system. Optional extras included carbon fiber trim, upgraded leather options, and a head-up display. The Competition package also included M-specific exterior styling cues, such as a more aggressive front bumper, side skirts, and a rear diffuser. The interior featured M-branded door sills, steering wheel, and seats. The convertible top was fully automatic and could be raised or lowered in approximately 20 seconds at speeds up to 50 km/h (31 mph).
Chassis & Braking
The M4 Convertible Competition 3.0 features a reinforced chassis compared to the standard 4 Series Convertible, designed to enhance rigidity and improve handling. The suspension utilizes independent coil springs in the front and an independent multi-link suspension in the rear. The braking system consists of ventilated discs at all four corners, with large calipers providing ample stopping power. The Competition model benefited from upgraded brake pads and rotors for improved fade resistance during track use. The standard wheels were 19-inch alloy wheels, with wider tires providing increased grip. An electronic limited-slip differential was available as an option, further enhancing traction and cornering performance.
Market Reception & Comparison
The M4 Convertible Competition 3.0 was generally well-received by automotive critics, who praised its performance, handling, and overall driving experience. Some critics noted that the convertible top added weight and compromised structural rigidity compared to the coupe, but the M4 Competition 3.0 still offered a compelling package. Compared to the standard M4 Convertible, the Competition model was seen as a more focused and engaging machine. Compared to the M4 Coupe, the convertible offered a different driving experience, prioritizing open-air enjoyment over ultimate track performance. Fuel economy, while not a primary concern for buyers of this vehicle, was reasonable for a high-performance convertible, averaging around 25.8 US mpg in combined driving.
Legacy
The S55 engine, while powerful, has been known to exhibit some long-term reliability concerns, particularly related to the cooling system and oil pump. However, with proper maintenance and preventative care, the engine can remain reliable for many years. The M4 Convertible Competition 3.0 has become a sought-after vehicle in the used car market, appealing to enthusiasts who appreciate its performance and open-air driving experience. Its combination of luxury, performance, and style has ensured its place as a modern classic. The F83 generation M4, and particularly the Competition variant, represents a high point in BMW’s convertible performance lineage.
