Pricing and Trims 

The BMW M3 and M4 are competitively priced for their respective market segments. The M3 starts at $76,000 for the base model, $80,200 for the Competition Sedan, and $85,300 for the Competition xDrive Sedan. Meanwhile, the M4 has a slightly higher entry cost due to its coupe design, starting at $79,100 for the base model, $83,200 for the Competition Coupe, and $88,300 for the Competition xDrive Coupe. These pricing differences reflect the M4’s sportier body style and distinct appeal as a performance coupe, while the M3 offers added practicality with its sedan configuration. 

Performance 

When comparing M3 vs M4, performance is a key factor that distinguishes the two models. Both vehicles are powered by a 3.0-liter BMW M TwinPower Turbo inline-6 engine but offer varying performance levels based on the trim. 

• BMW M3: 

• M3 Sedan: 473 hp, 0-60 mph in 4.1 seconds 

• M3 Competition Sedan: 503 hp, 0-60 mph in 3.8 seconds 

• M3 Competition xDrive Sedan: 523 hp, 0-60 mph in 3.4 seconds 

• BMW M4: 

• M4 Coupe: 473 hp, 0-60 mph in 4.1 seconds 

• M4 Competition Coupe: 503 hp, 0-60 mph in 3.8 seconds 

• M4 Competition xDrive Coupe: 523 hp, 0-60 mph in 3.4 seconds 

The primary difference lies in body style and how the design impacts handling. The M3, as a sedan, offers a slightly heavier build, while the M4’s coupe design is more streamlined for enhanced agility. This balance of design and performance is central to the M3 vs M4 decision. 

Fuel Economy 

The M3 and M4 deliver similar fuel economy, reflecting their shared drivetrain options. For rear-wheel-drive models, the estimated fuel efficiency is 16 MPG in the city and 23 MPG on the highway. All-wheel-drive versions, like the xDrive trims, have a slight reduction in efficiency due to added weight and drivetrain complexity. While fuel economy is not a primary consideration for performance vehicles, both models remain competitive within their segment. 

Interior

The interiors of the BMW M3 and M4 share many premium features but differ in space and layout. The M3, being a sedan, offers more rear passenger space, making it more practical for families or those frequently traveling with passengers. In contrast, the M4 focuses on a sportier cabin experience with a slightly more compact rear seating area due to its coupe design. Both models feature luxurious touches, such as Alcantara-wrapped steering wheels, optional carbon-fiber bucket seats, and advanced infotainment systems, ensuring that neither compromises on comfort or style. 

Cargo and Dimensions 

The BMW M3 and M4 differ significantly in cargo capacity and dimensions. The M3 provides 13 cubic feet of trunk space, making it one of the more practical options in the high-performance sedan category. Its larger overall dimensions also accommodate easier rear passenger access and more spacious storage. The M4, on the other hand, offers 12 cubic feet of trunk space and a more compact footprint, emphasizing a sleek, aerodynamic design over practicality. These differences highlight yet another aspect of the BMW M3 vs BMW M4 decision, with the M3 better suited for practicality and the M4 leaning toward a sportier lifestyle. 

Warranty and Safety 

Both the M3 and M4 come with identical warranty packages, reflecting BMW’s commitment to reliability and customer satisfaction. The warranty includes 4 years or 50,000 miles of limited coverage and a 12-year/unlimited mileage rust perforation warranty. In terms of safety, both vehicles come equipped with advanced features such as adaptive LED headlights, active driving assistance, and available upgrades like lane-keeping assist and collision warning systems. While the size and weight differences between the M3 and M4 may influence handling and safety dynamics, both models excel in providing state-of-the-art safety technology. 

Technology 

The technology suites in the M3 and M4 are nearly identical, showcasing BMW’s dedication to innovation. Both models feature the latest 14.5-inch curved display with iDrive 8, wireless Apple CarPlay and Android Auto, and optional head-up display for enhanced driving convenience. While the body styles influence how certain features are experienced—such as visibility and control layout—both models ensure a cutting-edge, driver-focused experience.
