The BMW M4 has long been a benchmark in the world of high-performance sports coupes, known for its balance between daily usability and track prowess. However, with the release of the G82 M4 in 2021, BMW introduced a new generation, replacing the highly respected F82 M4 (produced from 2014 to 2020). Let's dive into the key differences between these two models and see how BMW’s M division evolved its legendary coupe.
1. Design and Aesthetics
The most striking difference between the F82 M4 and the G82 M4 lies in the exterior design.
- F82 M4 (2014–2020): This model has a more understated, classic BMW look. Its design is more cohesive with BMW’s design language of the 2010s, featuring a relatively subtle kidney grille and smooth lines. The F82 M4 was praised for its balance of aggression and elegance, and many enthusiasts appreciated its relatively conservative design.
- G82 M4 (2021–Present): The G82 M4, however, took a bold leap forward with a highly polarizing design. The most talked-about feature is the enormous vertically-stacked kidney grille, which has split opinions among BMW fans and critics alike. In addition to the grille, the G82 has sharper, more aggressive lines, a wider stance, and a more muscular profile. It looks more modern and daring, with a clear departure from the F82’s subtler approach.
2. Engine and Powertrain
Both models share the inline-six engine configuration, a hallmark of BMW’s M division, but there are significant differences in power and technology.
- The F82 is powered by the S55 3.0L twin-turbocharged inline-six engine, producing 425 hp and 550 Nm (406 lb-ft) of torque in its standard form. In the Competition package, power was bumped to 444 hp, and in the limited CS version, it made 454 hp.
- The F82 M4 was available with a 6-speed manual transmission or a 7-speed dual-clutch automatic (DCT), delivering a more raw, connected driving experience for purists.
- The S55 engine was a development of the N55, featuring closed-deck architecture for added rigidity, water-to-air intercooling, and lightweight components, making it a potent force for its time.
- The G82 M4 features the new S58 3.0L twin-turbocharged inline-six, which is an evolution of the S55 engine but with significant updates. In the standard G82, it produces 473 hp and 550 Nm (406 lb-ft) of torque, while the Competition model boosts power to 503 hp and 650 Nm (479 lb-ft) of torque.
- A major shift is the introduction of all-wheel drive (xDrive) in the G82 M4 Competition. While rear-wheel drive is still available, xDrive adds an extra layer of capability and traction, especially in performance driving. However, enthusiasts can still switch to rear-wheel drive mode for a purer driving experience.
- The G82 M4 also offers a 6-speed manual transmission in the base model, but the Competition version uses an 8-speed automatic (not a DCT), a change that reflects a move towards smoother and more efficient power delivery.
3. Chassis and Handling
Both the F82 and G82 have a lightweight chassis and incorporate the latest technology for handling, but there are key differences in driving dynamics.
- F82 M4: Known for its lively, rear-wheel-drive nature, the F82 M4 was applauded for its engaging driving experience, especially with the manual transmission. However, some critics pointed out that the car could be unpredictable at the limit, with snap oversteer sometimes catching drivers off guard, especially on the track. This made the F82 thrilling but a bit unforgiving for less experienced drivers.
- G82 M4: With advancements in chassis design and driving aids, the G82 M4 is more refined, predictable, and stable under pressure. The new adaptive suspension system and enhanced chassis rigidity make the G82 feel more planted, especially at high speeds. The xDrive system (on the Competition model) adds another layer of grip and acceleration, while still allowing the driver to switch to rear-wheel-drive-only mode for traditional M-car thrills.
- The aerodynamics of the G82 have also been significantly improved, with enhanced airflow management around the body and underneath the car, improving downforce and high-speed stability.
4. Interior and Technology
Both models have high-quality interiors, but the G82 introduces more advanced technology and an updated cabin experience.
- F82 M4: The interior of the F82 is more minimalistic and driver-focused. While it offered BMW’s iDrive system, the technology, compared to modern standards, is relatively basic. The cabin materials are high-quality, and the seats are supportive for both track and road driving. However, it lacks some of the futuristic touches seen in newer models.
- G82 M4: The G82 M4 takes a big leap forward with a more luxurious, tech-packed interior. It features the latest iDrive 7.0 system, complete with a 12.3-inch digital instrument cluster and a 10.25-inch central display. Advanced driver assistance systems are also available, making the G82 a more high-tech and connected experience.
- The interior is more refined, with premium materials throughout, and the optional M Carbon bucket seats add a level of track-ready sportiness that blends with everyday usability.
5. Performance and Driving Experience
Performance is what defines both M4 generations, but there are notable differences in how each car feels on the road and track.
- F82 M4: It’s often regarded as more of a “raw” driving machine. The car delivers an intense, visceral experience, especially with the manual transmission. Its lighter weight and rear-wheel-drive setup make it more of an old-school driving experience, with less reliance on electronic aids. However, it can be unforgiving at the limit, making it more challenging to extract its full potential.
- G82 M4: The G82, on the other hand, feels more refined and sophisticated. The extra power, improved suspension, and optional xDrive system mean it offers more grip, confidence, and stability. It’s still capable of delivering a thrilling driving experience, but it’s more accessible and manageable, even for less experienced drivers. In short, it’s faster and more capable, but some purists may argue it’s slightly less engaging.
6. Sound and Exhaust Note
The exhaust note is another area where these two cars differ significantly:
- F82 M4: The S55 engine in the F82 was known for having a more synthetic sound due to its use of electronically augmented engine noise through the speakers, which drew some criticism from enthusiasts who prefer a more natural exhaust note. However, with the right aftermarket exhaust, the car can sound incredible.
- G82 M4: The S58 engine in the G82 has a more refined exhaust note. While it too uses artificial enhancement through the cabin speakers, the engine note is generally regarded as more pleasing and aggressive than its predecessor, thanks to improved exhaust tuning and less reliance on electronic augmentation.
Conclusion: F82 M4 vs. G82 M4
Both the F82 M4 and the G82 M4 are exceptional cars in their own right, but they cater to different kinds of drivers:
- The F82 M4 is for the purist who wants a raw, visceral, and sometimes wild driving experience. It’s a lighter, more aggressive machine that rewards skill and precision but can be unforgiving at the limit.
- The G82 M4 is a more refined, powerful, and advanced car that delivers incredible performance with more stability and confidence. It’s faster, more sophisticated, and more comfortable to live with daily, but some enthusiasts may miss the rawness of the previous generation.
In essence, if you're looking for a more analog, connected driving experience, the F82 might be the one to seek. If you want cutting-edge technology, increased performance, and the option for all-wheel drive, the G82 is the clear choice. Both cars uphold BMW’s legacy of delivering thrilling driving experiences—just in different ways.
