BMW M3 2021 Review

In the high-performance four-door coupe market, the combination of a 3.0T six-cylinder engine and over 500 horsepower remains the focal point for car enthusiasts. The 2021 BMW M3 Competition, as a core contender in this segment, not only continues the sporty genes of the M series but also balances practicality with its four-door layout. This time, we got the version with the Innovation Package, and the main purpose is to see if it can find the precise balance between performance, luxury features, and daily usability.

From the exterior, the 2021 M3 Competition's most recognizable feature is the large-size kidney grille, which, though controversial, has a strong visual impact. Coupled with the two raised lines on the hood, it clearly signals its performance orientation at a glance. The body side lines are compact, with widened front and rear fenders, front 19-inch and rear 20-inch multi-spoke wheels, as well as wide tires measuring 275/35R19 in the front and 285/30R20 in the rear, achieving a very sporty posture. At the rear, the adaptive LED taillights are treated with a smoked effect, and the double-sided quad-round exhaust pipes at the bottom are a classic M-series design. The exhaust sound at startup instantly ignites the desire to drive. In terms of lighting systems, the adaptive LED headlights support automatic high-beam adjustment, adjusting the illumination range according to oncoming vehicles when driving at night, which is quite practical.

Sitting inside, the interior strikes a good balance between a sporty atmosphere and luxury. The leather-wrapped sport steering wheel features M mode buttons, offering a solid grip, and the 3 and 9 o'clock positions are perforated for better anti-slip properties. The instrument panel is a 12.3-inch full LCD display, which shows performance data such as rpm and torque when switched to M mode. The 10.25-inch central touchscreen supports wireless CarPlay and Android Auto, with responsive and smooth performance. The configuration upgrades brought by the Innovation Package are quite noticeable, including a HUD head-up display, Harman Kardon sound system, and a 360-degree panoramic camera, making daily use more convenient. The seats are M-exclusive sporty seats with strong support and manually adjustable shoulder and lumbar support, ensuring comfort even during long drives.

In terms of space, with a wheelbase of 2857mm, there is about two fists of legroom in the rear when the front seats are adjusted to a proper position, and there’s also a fist of headroom. Accommodating three adults in the rear doesn’t feel overly cramped. The storage space isn’t particularly outstanding, but the front door panels can fit two bottles of water, the center armrest box has adequate depth, and the rear offers independent air conditioning vents and USB ports, meeting the needs of daily family use without issue.

As for performance, the 3.0T inline six-cylinder twin-turbocharged engine delivers a maximum power of 510PS and a peak torque of 650N·m, paired with an 8-speed automatic transmission. In standard mode, the power output feels relatively smooth, with no abrupt sense of thrust during starts, making it suitable for daily commuting. When switched to M mode, the throttle response becomes very sensitive, and with a deeper press, the maximum torque is unleashed at 2750rpm. The official data for 0-100 km/h acceleration is 3.9 seconds. In actual tests, when the ESP is turned off, there’s slight wheel spin at the start, but overall acceleration remains very linear. The power reserve is ample in the later stages, and overtaking is easy with just a light press on the accelerator.

Handling is the core strength of the M3 Competition. The steering system is highly precise with almost no play in the steering wheel, providing clear feedback on road conditions during cornering. The chassis uses a front double-wishbone and rear multi-link suspension, which offers excellent support. Body roll is minimal during fast cornering, and the suspension effectively absorbs road bumps. Even on rough roads, there aren't significant vibrations transmitted into the cabin. The braking system also performs well, with four-piston front and single-piston rear brake calipers matched with ventilated perforated discs, providing short braking distances and no brake fade during repeated braking. In terms of fuel consumption, it averages around 10-12L/100km under mixed driving conditions and can drop to about 8L/100km during pure highway driving. For a 510-horsepower performance car, this can be considered reasonable.

In terms of driving comfort, the sound insulation is quite good. Wind and tire noise are not very apparent during high-speed driving, and the Harman Kardon sound system can mask most of the noise. While the sport seats offer strong support, they are not too firm, making long-distance driving comfortable. The transmission has an intelligent shifting logic, maintaining low RPMs during daily driving to reduce fuel consumption, but quickly downshifting for spirited driving to optimize the engine's power output.

Overall, the 2021 BMW M3 Competition's key advantages are clear: powerful performance, precise handling, and practicality with its four-door layout and decent space. The configuration upgrade brought by the Innovation Package also enhances its sense of luxury. Compared to competitors in the same segment, such as the Mercedes-AMG C63 S, the M3 Competition has superior power specifications and a more affordable price, while it offers significant performance and configuration improvements over the standard 3 Series. It is mainly suited for two types of consumers: those who love performance cars but also need a daily family vehicle, and young people seeking both driving precision and a sense of luxury.

In summary, the 2021 BMW M3 Competition is a high-performance four-door coupe that balances performance and practicality. It satisfies your need for speed while being capable of daily family use. If you are looking for a car that can handle both the track and the streets, this would be an excellent choice.
