Powertrain & Engine Architecture
At the heart of the M4 Competition xDrive lies the S58B30A, a 3.0-liter inline-six engine. This engine is a masterpiece of modern engineering, featuring a closed-deck block for enhanced rigidity, forged crankshaft, and lightweight connecting rods. It utilizes direct fuel injection operating at 350 bar, ensuring precise fuel delivery for optimal combustion. The engine’s twin-scroll turbochargers, positioned within the V of the engine, minimize turbo lag and provide a broad torque curve. BMW’s VALVETRONIC technology, combined with Double-VANOS variable valve timing, further optimizes engine efficiency and responsiveness. The M Steptronic 8-speed automatic transmission is specifically tuned for performance, offering quick and precise shifts, and features Drivelogic which allows the driver to select different shift characteristics. The xDrive all-wheel-drive system intelligently distributes power between the front and rear axles, enhancing traction and stability, particularly during acceleration and cornering. A rear-wheel-drive mode can be selected for a more traditional driving experience.
Driving Characteristics
The M4 Competition xDrive delivers a truly exhilarating driving experience. The 510 horsepower and 650 Nm (479 lb-ft) of torque provide relentless acceleration, with 0-60 mph achieved in just 3.3 seconds. The xDrive system ensures optimal grip in a variety of conditions, allowing for confident cornering at high speeds. The M Steptronic transmission shifts quickly and smoothly, whether in automatic or manual mode. Compared to the rear-wheel-drive M4, the xDrive variant offers increased stability and predictability, making it more accessible to a wider range of drivers. However, some purists argue that the xDrive system slightly diminishes the car’s playful character. The gear ratios are optimized for both acceleration and high-speed cruising, providing a balance between performance and efficiency.
Equipment & Trim Levels
The M4 Competition xDrive came standard with a comprehensive list of features, including M Sport seats, Merino leather upholstery, a head-up display, a 12.3-inch digital instrument cluster, and a 10.25-inch central infotainment screen with iDrive 8 operating system. Optional extras included carbon fiber trim, M Sport brakes with carbon-ceramic rotors, and a premium sound system. The interior design emphasized a driver-focused layout, with all essential controls within easy reach. Exterior features included M-specific aerodynamic enhancements, such as a front splitter, rear diffuser, and quad exhaust outlets.
Chassis & Braking
The M4 Competition xDrive features a sophisticated chassis designed for optimal handling and stability. The front suspension utilizes a spring-strut design, while the rear employs an independent multi-link setup. Adaptive M suspension is standard, allowing the driver to adjust the damping characteristics to suit their preferences. The braking system consists of ventilated discs at all four corners, providing ample stopping power. The M Compound brakes are standard, with the option to upgrade to M Carbon Ceramic brakes for even greater performance and fade resistance. The steering system is an electric power-assisted rack-and-pinion setup, offering precise and responsive steering feel.
Market Reception & Comparison
The M4 Competition xDrive was generally well-received by automotive critics, who praised its exceptional performance, handling, and technology. However, the car’s controversial styling, particularly the large kidney grilles, drew criticism from some quarters. Compared to the standard M4 and the M4 Competition RWD, the xDrive variant offered superior traction and acceleration, but at a slightly higher price point. Fuel economy was reasonable for a high-performance car, with combined fuel consumption ranging from 10-10.1 l/100 km. Reliability has been generally good, although some owners have reported minor issues with the infotainment system.
Legacy
The M4 Competition xDrive M Steptronic represents a significant step forward in BMW M’s pursuit of performance and technology. The S58 engine is widely regarded as one of the best inline-six engines ever produced, and the xDrive system has proven to be a valuable asset in enhancing traction and stability. On the used car market, these models hold their value well, reflecting their desirability and performance capabilities. The combination of power, handling, and all-weather capability makes the M4 Competition xDrive a compelling choice for enthusiasts seeking a high-performance coupe that can be enjoyed year-round. The G82 generation, and particularly this top-spec variant, will likely be remembered as a defining moment in the evolution of the M4.
