Why it stands out

The 2021 BMW 3 Series stands out because it blends the brand’s traditional strengths with a broad range of modern technology and performance choices. In Canada, this generation comes only as a four-door sedan, and BMW offers it in several distinct forms, from the 330i and 330e to the M340i and M3. That variety is a big part of its appeal: buyers can choose a version that leans toward efficiency, everyday speed, or outright performance without leaving the 3 Series family.

BMW has also kept the cabin and tech package current. For 2021, the car benefits from the generation’s updated infotainment system and redesigned dashboard, which replaces the separate instrument cluster and centre screen with a curved display. Standard wireless Apple CarPlay and Android Auto are included, along with over-the-air software updates and an available head-up display. Safety equipment is led by standard forward collision warning with city collision mitigation, while additional driver-assistance features are available on some examples through an optional package.

Even with all that equipment, the 2021 BMW 3 Series remains recognisably a 3 Series: sober, business-like, and luxurious, but a little tight in the back. It is practical enough for a small family, though it is effectively a four-seater in most situations. Trunk space is ample in most versions, but the plug-in hybrid gives up some cargo room to its battery pack. Owners also tend to value the car’s handling, performance, and fuel economy, though some have noted concerns with the audio system and mechanical noises.
