2021-2024 BMW M3 (G80) Competition 3.0 (510 Hp) M xDrive M Steptronic

The BMW M3 (G80) Competition 3.0 xDrive, equipped with the 510 horsepower M xDrive and M Steptronic transmission, represents the pinnacle of performance within the G80 M3 generation, produced from 2021 to 2024. Positioned as the top-tier variant, it caters to enthusiasts seeking uncompromising power and all-weather capability. This model builds upon the foundational advancements of the G80 platform, introducing a sophisticated all-wheel-drive system and a highly tuned version of BMW’s S58 inline-six engine. It’s a significant departure from previous M3 generations, marking the first time an M3 has been offered with a factory-installed all-wheel-drive option.

Technical Specifications

Powertrain & Engine Architecture

At the heart of the M3 Competition xDrive lies the S58B30A, a 3.0-liter inline-six engine. This engine is a masterpiece of engineering, featuring a closed-deck block for enhanced rigidity, forged crankshaft, and lightweight connecting rods. It utilizes direct fuel injection operating at 350 bar, paired with twin-scroll turbochargers, one for each bank of three cylinders, to minimize turbo lag and maximize responsiveness. The valvetrain incorporates BMW’s VALVETRONIC technology for precise throttle control and Double-VANOS variable valve timing for optimized efficiency and power delivery. The engine produces 510 hp at 6,250 rpm and a substantial 650 Nm (479 lb-ft) of torque available from 2,750 to 5,500 rpm. The M Steptronic 8-speed automatic transmission is specifically tuned for rapid shifts and features Drivelogic, allowing the driver to select from different shift programs. The xDrive all-wheel-drive system is rear-biased, prioritizing power delivery to the rear wheels for a traditional M car feel, but can seamlessly distribute torque to the front wheels when traction is needed.

Driving Characteristics

The M3 Competition xDrive delivers exhilarating performance. The all-wheel-drive system provides exceptional grip, enabling blistering acceleration – 0 to 60 mph in approximately 3.3 seconds. The M Steptronic transmission offers both smooth automatic operation and precise manual control via paddle shifters. Compared to the rear-wheel-drive M3, the xDrive variant offers increased stability and confidence, particularly in adverse weather conditions. However, some purists argue that the xDrive system slightly diminishes the playful, tail-happy characteristics of the traditional M3. The gear ratios are optimized for both acceleration and high-speed cruising, providing strong pull in any gear. The engine’s broad torque curve ensures effortless overtaking and a responsive driving experience.

Equipment & Trim Levels

The M3 Competition xDrive came standard with a comprehensive suite of features, including M Sport seats, Merino leather upholstery, a head-up display, a 12.3-inch digital instrument cluster, and a 14.9-inch central infotainment display. Standard safety features included lane departure warning, forward collision warning, and automatic emergency braking. Optional extras included carbon fiber exterior trim, M carbon bucket seats, a premium sound system, and various driver assistance packages. Interior color options were extensive, allowing for a high degree of personalization. The Competition trim also included unique exterior styling cues, such as black kidney grilles and M-specific side mirrors.

Chassis & Braking

The G80 M3 features a robust chassis designed for high-performance driving. The front suspension utilizes a MacPherson strut design with a transverse stabilizer, while the rear employs a multi-link setup, also with a stabilizer. The Competition xDrive model benefits from adaptive M suspension, allowing the driver to adjust the damper settings for optimal comfort or track performance. Braking duties are handled by large, ventilated discs at all four corners, with M Compound brakes standard and M Carbon Ceramic brakes available as an option. The braking system is paired with ABS and dynamic stability control (DSC) for enhanced safety and control.

Market Reception & Comparison

The M3 Competition xDrive was generally well-received by automotive critics, praised for its exceptional performance, handling, and all-weather capability. However, the controversial exterior styling, particularly the large kidney grilles, drew considerable debate. Compared to the standard M3 and the M3 Competition (rear-wheel drive), the xDrive variant offered superior traction and stability, but at a slightly higher price point. Fuel economy, while not a primary concern for M3 buyers, was reasonable for a high-performance vehicle, averaging around 23.5 mpg in combined driving. Reliability reports have been generally positive, although some owners have reported minor issues with the infotainment system.

Legacy

The M3 Competition xDrive represents a significant evolution in the M3 lineage, embracing all-wheel drive for the first time. Its advanced powertrain, sophisticated chassis, and comprehensive feature set have established it as a benchmark in the high-performance sedan segment. On the used car market, these models hold their value well, reflecting their desirability and performance credentials. The S58 engine is known for its durability and tunability, making the M3 Competition xDrive a popular choice for enthusiasts seeking a powerful and capable performance car. It’s a vehicle that will likely be remembered as a pivotal moment in the M3’s history, bridging the gap between traditional performance and modern technology.
