Defining the BMW M4: Models and Generations
Understanding the BMW M4 requires a look into its origins and the different models that have evolved over time. The M4 emerged as the coupe and convertible variant of the legendary M3, carrying forward its legacy of high performance and driver-focused engineering.
The Genesis of the M4: Separating from the M3
Historically, the “M” badge was exclusively associated with the BMW 3 Series. However, with the introduction of the F32/F33/F36 generation, BMW decided to split the coupe and convertible models into the 4 Series. This led to the birth of the M4, inheriting the performance DNA of its M3 sibling while establishing its own identity. This separation allowed BMW to further differentiate the coupe and convertible models, focusing on distinct design elements and target audiences [www.bmwusa.com].
Notable Generations: F82/F83 and G82/G83
The BMW M4 has had two primary generations:
- F82/F83 (2014-2020): The first generation M4, sharing its engine with the F80 M3, featured a 3.0-liter twin-turbocharged inline-six engine (S55). This engine delivered impressive power and responsiveness, quickly establishing the M4 as a formidable competitor in the high-performance coupe segment. The F82 was the coupe, while the F83 was the convertible version.
- G82/G83 (2021-Present): The current generation M4 boasts a new design language, a more powerful engine (S58), and available all-wheel drive (M xDrive). The G82 again designates the coupe, and the G83 the convertible. The G82/G83 generation represents a significant leap in performance and technology, pushing the boundaries of what’s expected from a high-performance coupe [www.bmw.com.sg].
Competition Models: Enhanced Performance and Aesthetics
Within each generation, BMW offers “Competition” variants of the M4. These models receive further enhancements focused on increased power output, a sharper chassis setup, and distinctive styling details. The Competition models typically feature:
- Increased horsepower and torque
- Revised suspension tuning for improved handling
- Unique exterior and interior trim elements
- Sportier exhaust systems for enhanced sound
- Lightweight M sports seats for better support.
Performance figures for the M4 competition can reach up to 390 kW (530 hp) thanks to the High-Performance M TwinPower Turbo inline 6-cylinder petrol engine [www.bmw.com.sg, www.pml-bmw.com.sg, www.bmweurokars.com.sg, www.bmw.com].
