2021 BMW M4: A Detailed Overview
The 2021 BMW M4 represents the latest evolution of BMW's iconic performance coupe and convertible, marking a significant redesign with a bold new aesthetic and enhanced driving dynamics. This generation introduces the potent S58 engine, a more aggressive styling language, and advanced technology to deliver an even more exhilarating driving experience.
Highlights
-
Engine and Performance:
- S58 Twin-Turbocharged Inline-Six: At the heart of the 2021 M4 lies the robust S58 engine, a powerhouse that also serves duty in other high-performance BMW models. In the M4, it produces a formidable 503 horsepower and 479 lb-ft of torque in its Competition guise.
- Transmission Options: A significant change for this generation is the exclusive availability of an 8-speed M Steptronic automatic transmission. While a manual transmission was previously a hallmark of M cars, BMW opted for the faster-shifting and more efficient automatic for this iteration of the M4.
- M xDrive All-Wheel Drive: For the first time in the M4's history, M xDrive is offered, providing a rear-biased all-wheel-drive system that can be fully disengaged, allowing for a classic rear-wheel-drive experience. This enhances traction and acceleration, especially in challenging conditions.
- Adaptive M Suspension: This sophisticated system continuously adjusts damping forces based on road conditions, driving style, and selected drive modes, offering a remarkable balance between sporty handling and everyday comfort.
- M Sport Differential: An electronically controlled limited-slip differential optimizes traction and stability by precisely distributing torque between the rear wheels, enhancing agility during cornering and acceleration.
-
Safety Features:
- Driving Assistance Professional Package: This comprehensive suite includes features like Active Cruise Control with Stop & Go, which automatically maintains a set speed and distance to the vehicle ahead, and can even bring the car to a complete stop and resume driving.
- Steering and Lane Control Assistant: This system helps keep the M4 centered in its lane by providing gentle steering interventions, working in conjunction with the Active Cruise Control.
- Lane Keeping Assistant with Side Collision Avoidance: Alerts the driver to unintentional lane departures and can apply corrective steering to prevent a potential side collision.
- Automatic High Beams: Intelligently switches between high and low beams based on traffic conditions, improving nighttime visibility without dazzling other drivers.
- Parking Assistant Plus: Includes Surround View and Remote 3D View, providing a 360-degree aerial view of the vehicle and its surroundings, making parking in tight spaces significantly easier.
-
Trims:
- BMW M4 Coupe: The standard offering, delivering potent performance and the signature M driving experience in a stylish coupe body style.
- BMW M4 Competition Coupe: Elevates performance with a more powerful engine tune and the aforementioned M xDrive all-wheel-drive system as standard.
- BMW M4 Convertible: Offers the open-air exhilaration of a convertible, with the same powerful engines and advanced technology as its coupe counterparts.
-
Other Notable Aspects:
- Distinctive Styling: The 2021 M4 features a polarizing vertical kidney grille design that sets it apart from previous generations and other BMW models. While divisive, it undeniably contributes to a bold and aggressive stance.
- M-Specific Interior: The cabin is driver-focused, with supportive M Sport seats, an M-specific steering wheel with programmable M buttons, and performance-oriented displays on the digital instrument cluster and infotainment screen.
- Carbon Fiber Roof: As standard on coupe models, the carbon fiber reinforced plastic (CFRP) roof lowers the center of gravity, improving handling dynamics and contributing to the M4's lightweight construction.
What to Expect
Owning a 2021 BMW M4 is an experience defined by performance and refinement. The car is engineered to be a capable daily driver, offering a comfortable ride in its Comfort mode, yet transforming into a track-ready machine when Sport or Sport+ modes are engaged. The acceleration is potent, the handling is precise, and the engine note is a rewarding soundtrack.
- Maintenance: As a high-performance vehicle, the M4 will likely have higher maintenance costs compared to a standard luxury car. Regular oil changes, filter replacements, and brake pad/rotor replacements are expected, and these are often more specialized and thus pricier for M models. It is highly recommended to follow BMW's recommended maintenance schedule meticulously, ideally at a BMW-certified service center, to preserve the longevity and performance of the vehicle.
- Insurance: Due to its high performance, cost of repairs, and luxury classification, insurance premiums for the 2021 BMW M4 are generally higher than average. Factors such as the driver's age, driving record, location, and chosen coverage levels will significantly impact the final cost.
Potential Considerations
- Polarizing Design: The redesigned front-end, particularly the large vertical kidney grille, is a significant departure from previous M4 generations and can be polarizing. Potential buyers should assess if they find the styling appealing.
- Automatic Transmission Only: For enthusiasts who prefer a manual transmission, the absence of a clutch pedal in the 2021 M4 will be a notable drawback. While the M Steptronic is excellent, it doesn't offer the same level of driver engagement for purists.
- Stiff Ride in Sport Modes: While adaptable, in its sportiest settings, the M4 can deliver a firm ride that might be too harsh for some on less-than-perfect road surfaces.
Overall Summary
The 2021 BMW M4 is a formidable performance coupe and convertible that pushes the boundaries of what an M car can be. With its powerful S58 engine, the availability of M xDrive, and a host of advanced technology, it offers an exceptional blend of blistering performance, sharp handling, and sophisticated luxury. While its bold styling and exclusive automatic transmission might not appeal to every enthusiast, for those seeking a thrilling and capable driver's car with a premium badge, the 2021 M4 is a compelling proposition.
