Differences between M3 and M4?
2 Answers
M3 emphasizes practicality, while M4 is more performance-focused. Both are rear-wheel-drive models and represent the sports benchmarks in their class. The specific differences are as follows: 1. Body Structure: The BMW M3 features a 4-door, 5-seat sedan structure, whereas the BMW M4 adopts a 2-door, 4-seat coupe design. The M4 has a lower body height, resulting in a lower drag coefficient, faster acceleration, and a more sporty appearance. The rear suspension of the M3 is a multi-link independent suspension, while the M4 uses a five-link independent suspension. Additionally, the rear seats of the M4 can be folded down entirely, whereas the M3 only allows for proportional folding. 2. Interior: The BMW M4 comes equipped with factory-installed ambient lighting and a 10.25-inch color touchscreen on the dashboard, supporting single-disc DVD playback. 3. Performance: The most significant difference between the BMW M4 and M3 is evident in their top-performance variants. The BMW M4 CS model boasts a maximum engine torque of 600 Nm, a maximum power output of 338 kW (460 hp), and an electronically limited top speed of 280 km/h. In contrast, the top-tier BMW M3 model with the same displacement has a maximum engine torque of 550 Nm, a maximum power output of 331 kW (450 hp), and an electronically limited top speed of 250 km/h. 3. Features: There are also some differences in specific features. For example, the M3 is equipped with BMW run-flat tires (capable of driving with zero tire pressure), a Harman Kardon sound system, and advanced driver-assistance devices like a 360-degree camera. The BMW M4, on the other hand, offers heated front seats.
I've always been fascinated by BMW's designs, especially the differences between the M3 and M4, which are mainly reflected in their body styles. The M3 is a classic four-door sedan with more spacious rear seats, making it ideal for family or friends' outings, and its trunk is also practical. The M4, on the other hand, is a sleek two-door coupe with more sporty and elegant lines. Its low-slung body makes it particularly eye-catching on the streets, though getting in and out of the rear seats can be a bit tight. Both models are equipped with a 3.0-liter inline-six engine, tuned to roughly the same output of around 510 horsepower, delivering fierce acceleration. However, they feel different to drive: the M4 is more agile in corners, with a slightly lower center of gravity, making it more stable at high speeds. The M3 also handles brilliantly but is a tad heavier due to the extra doors. For daily use, I prefer the convenience of the M3—taking the kids out on weekends isn't a hassle. But if it's about looking cool and cruising, the M4's two-door design and mirror styling are more distinctive, turning heads everywhere. Choosing between them depends on your lifestyle—if you frequently carry passengers or need practicality, the M3 is the better value; if it's purely for driving pleasure, the M4 has the upper hand.
