What is the difference between BMW 4 Series and M4?

[MacDiana]

BMW 4 Series and M4 have the following differences: 1. Different engines: BMW M4: Equipped with a twin-turbocharged V8 engine. BMW 4 Series Coupe: Uses 2.0T high/low power and 3.0T engines. 2. Different features: BMW M4: Adopts the front face design of the new 3 Series, with sharp Angel Eye headlights connected to blackened quadrilateral air intake grille, and front bumper featuring embedded lower lip spoiler. BMW 4 Series Coupe: The polygonal LED headlights have a more aggressive design. From the side view, the car features a two-door Coupe shape with elegant overall body lines.

The BMW 4 Series and M4 may look like relatives, but they're worlds apart under the skin. I test drove both models last month - the regular 4 Series drives like a comfortable commuter car, with its 2.0T engine being adequate but never heart-racing. The M4 is an entirely different beast; you can feel its racing DNA the moment you sit inside. The 3.0T inline-six engine pins you back into the bucket seats with just a stab of the throttle. The chassis tuning is completely different too - the 4 Series handles speed bumps with composure, while the M4 is so stiff you can count every pavement joint. However, the M4's rear seats are practically unusable, and its fuel consumption is at least 30% higher - definitely think twice before using it for daily city commutes.

When it comes to practicality, I'd definitely choose the regular 4 Series. It's perfect for commuting to work and picking up kids, with enough rear space for a child safety seat. The M4, on the other hand, is purely a driving toy. Last time I borrowed a friend's M4 for mountain roads, the feeling of hugging the ground through corners was exhilarating, but the heavy steering wheel in daily traffic could give you biceps. The configuration gap is even bigger—the M4 comes with a carbon fiber roof and track-ready dashboard, plus brake discs two sizes larger, all for nearly 400,000 RMB more. Honestly, unless you frequently hit the track, the regular 4 Series is the wiser choice.

The differences are evident in the design, and I paid special attention to the details. The 4 Series' kidney grille is more elegant, while the M4's oversized air intake looks like a wide-open mouth. The wheels are also different—the 4 Series comes standard with 18-inch rims, whereas the M4 directly features 19-inch forged wheels with eye-catching blue brake calipers. Opening the hood makes it even more obvious: the M4's bulging engine cover hides a 435-horsepower beast, while the standard 2.0T engine bay is much more orderly. The exhaust design is worlds apart—the M4's quad exhaust sounds like firecrackers when revving.

Driving two different models reveals their distinct personalities. The 4 Series is an elegant daily companion, with a cabin so quiet at 60 km/h cruising speed that you can clearly hear the tire noise. The M4 roars to announce its presence the moment it ignites, with exhaust backfires crackling during downshifts. The suspension tuning best showcases their engineering - the 4 Series handles bumps effortlessly while the M4 would spill your coffee over a manhole cover. The seat support differs by two grades too: the standard seats won't fatigue your back on long drives, whereas the M4's bucket seats lock you firmly during cornering but leave your butt numb after two hours.

I have deep personal experience with maintenance. Regular maintenance for the 4 Series is similar to the 3 Series, with an oil change costing just over a thousand. Every time the M4 goes to the dealership, it hurts—Brembo brake pads start at 4,000 for a set, and a single 20-inch performance tire costs over 2,000. Fuel consumption is even more staggering: the M4 easily hits 15 L/100km in the city, while the 4 Series can be kept around 9 L/100km with gentle driving. Resale value is a bright spot, though—a five-year-old M4 can still fetch 70% of its original price, while the standard version drops to just 50%. If you're on a tight budget, you really need to weigh the long-term costs.
