Engine and Performance Specs

Both models use BMW’s S58 3.0-litre twin-turbocharged inline-six engine. In Canadian BMW data, base M3 and M4 models produce 473 hp and 406 lb-ft of torque, paired with a 6-speed manual transmission and rear-wheel drive.

Drivetrain	RWD / AWD	RWD / AWD

In real-world terms, these figures translate into very similar performance. Manual versions offer a more hands-on driving experience, while automatic AWD versions improve traction and acceleration, which can be useful in Canadian driving conditions.

BMW M3 vs M4 Weight and Dimensions: How It Affects Performance

BMW Canada lists both vehicles with nearly identical dimensions, but the M3 is slightly taller.

Measurement	BMW M3	BMW M4 Coupe
Length	4,804 mm	4,804 mm
Width	1,887 mm	1,887 mm
Height	1,437 mm	1,397 mm
Wheelbase	2,857 mm	2,857 mm
Cargo	480 L (M3)	440 L (M4 Coupe)
Fuel Tank	59 L	59 L

 Weight varies by trim and body style. The M4 Convertible includes additional structural reinforcement compared with the coupe, which affects weight, cargo space, and driving feel.

Acceleration and Top Speed

Performance figures are closely matched across both models. The base manual versions reach 100 km/h in approximately 4.2 seconds, while Competition xDrive variants reduce that time to approximately 3.5 seconds.

Model	0–100 km/h	Top Speed
BMW M3	4.2 seconds	250 km/h
BMW M3 Competition xDrive	3.5 seconds	250 km/h
BMW M4 Coupe	4.2 seconds	250 km/h
BMW M4 Competition xDrive	3.5 seconds	250 km/h

BMW Canada notes that top speed can increase to 290 km/h with the optional M Driver’s Package. 

BMW M3 vs BMW M4 Price: Cost, Value, and Trim Differences

Canadian pricing varies by model year, trim, configuration, options, dealer inventory, freight and PDI, taxes, and applicable fees. As a general guide, the M3 Sedan typically starts slightly below the M4 Coupe, while the M4 Convertible carries the highest starting price because of its open-top configuration and additional structural requirements.

Model	Canadian Price Positioning	Notes
BMW M3 Sedan	Typically Lowest Starting Point in This Comparison	Four-Door Sedan Layout; Strong Value for Buyers Wanting M Performance With Daily Usability
BMW M4 Coupe	Typically Priced Slightly Above the M3 Sedan	Coupe Styling with Similar Performance and a More Focused Design
BMW M4 Competition Convertible	Typically Highest Starting Point	Adds Open-Air Driving, Higher Cost, Added Weight, and Reduced Cargo Practicality

For Vancouver buyers, final pricing includes freight & PDI, GST, and B.C. PST. B.C. PST varies based on vehicle price (typically 10%–20%), and a federal luxury tax may apply to vehicles priced above $100,000 before taxes. 

Fuel consumption varies by trim, drivetrain, and body style, with current Canadian listings generally placing M3 and M4 models in the low-to-mid 12 L/100 km combined range. Buyers should confirm the exact NRCan rating for the specific model and configuration they are considering.

BMW M3 vs BMW M4 Design and Exterior Differences

The M3 uses a traditional sedan design with four doors and a higher roofline. This makes it more practical for passengers and everyday use, especially when rear-seat access and visibility are important in city driving conditions.

The M4 uses a coupe design with a lower roof and longer doors. The convertible version adds open-air driving, which is not available in the M3 lineup, and gives the car a more distinct visual presence on the road.

The design difference is one of the main reasons buyers compare these models, as it directly affects both appearance and day-to-day usability.

BMW M3 vs M4 Interior and Technology

Both models feature BMW’s curved display, which combines a 12.3-inch digital instrument cluster and a 14.9-inch central touchscreen into a single glass panel. The system runs on iDrive 8.5 and supports Apple CarPlay and Android Auto, along with navigation, voice controls, and over-the-air updates. The layout is modern and consistent across both vehicles, with similar materials, controls, and overall cabin design.

The difference is mainly in usability. The M3 allows easier rear-seat access and offers more flexibility for passengers, especially in daily driving situations. The M4 coupe, due to its two-door design and lower roofline, has tighter rear seating and requires more effort for entry and exit.

BMW M3 vs BMW M4 Convertible: Is It Worth It?

The BMW M4 is the only model in this comparison available as a convertible. It uses a soft-top design, which helps reduce weight compared to older hardtop systems but still adds some mass compared to the coupe.

The convertible offers a different driving experience, particularly during warmer months. However, it also comes with trade-offs, including slightly reduced acceleration, less cargo space, and higher cost.

In a Canadian climate, including Vancouver, the convertible may see less use during colder or wetter months. It tends to suit buyers who place importance on open-air driving rather than year-round practicality.

BMW M3 vs M4 Driving Experience

Both models deliver similar levels of performance, but the driving experience varies slightly due to body style and weight distribution.

The M3 feels more balanced for everyday driving, with better outward visibility and easier maneuverability in urban environments. The four-door layout also makes it more convenient for passengers.

The M4, with its coupe structure, offers a slightly more focused feel. The lower seating position and body rigidity can contribute to a more connected driving experience, particularly on open roads.

In typical Vancouver driving conditions, the differences are noticeable but not dramatic.

BMW M3 vs M4: Which One Should You Choose?

The right choice depends less on outright speed and more on how you plan to use the car.

Best for daily driving: Choose the BMW M3 if you want M performance with easier rear-seat access, better passenger practicality, and a more convenient four-door layout.

Best for performance enthusiasts: Choose either the M3 Competition xDrive or M4 Competition xDrive if acceleration, grip, and all-weather traction are priorities.

Best for style-focused buyers: Choose the BMW M4 Coupe if you prefer a lower, more dramatic two-door profile.

Best for open-air driving: Choose the BMW M4 Convertible if the top-down experience matters more than maximum practicality.

Best for families or regular passengers: Choose the BMW M3. It offers the same core performance with easier access and more everyday flexibility.

Best for Vancouver driving: Competition xDrive versions of either model are especially appealing for drivers who want added traction in wet conditions while keeping the performance character of a BMW M car.

BMW M3 vs BMW M4: Pros and Cons of Each Model

Before making a final decision, it helps to look at how each model performs in everyday use. While both share similar performance, their differences in design and practicality can influence long-term ownership experience.

BMW M3 Pros and Cons

The BMW M3 offers four-door practicality, easier passenger access, and 480 L of cargo space. It delivers the same performance as the M4 but does not offer a convertible and has a more traditional sedan design.

BMW M4 Pros and Cons

The BMW M4 offers coupe and convertible body styles with the same performance as the M3. It features a lower profile design but has reduced rear-seat access, less practicality, and higher pricing in upper trims.
