Serving Milwaukee, WI

Should you focus your attention on the 2020 BMW 3 Series or the 2021 version for your next purchase? At BMW of Milwaukee North, we always give our customers our full attention throughout their model research and the rest of their purchase experience. We want you to feel confident that the sedan you head home in is right for your expectations and lifestyle. The 2020 and 2021 3 Series sedans are part of the line’s seventh generation, and the 2021 3 Series introduces a few updates that could sway your vehicle selection.


The primary gas-powered engines that are in the 2020 3 Series are unchanged going into the 2021 model year. These include a 255-horsepower, four-cylinder twin-turbo engine, and a 382-horsepower, I-6 twin-turbo engine. Notably, the 2021 3 Series adds a 330e plug-in hybrid variation to the mix. This engine draws 248 net horsepower from a lithium-ion battery and a four-cylinder gas engine.


The 2021 3 Series has the same appealing exterior design as you will appreciate on the 2020 BMW 3 Series. Everything from the deep air vents in the front bumper to the elongated, dramatic LED headlights are the same. The 3 Series is an undeniably regal sedan, and it also brings a modern, athletic touch to its look through the deep contouring on the sides and its low ground clearance. A powered sunroof, integrated turning signals in the heated mirrors and dual exhaust tips all add to its aesthetic appeal.


The interior design and features in the 2020 and 2021 3 Series sedans are equivalent in most areas. However, drivers who opt to drive the 2021 BMW 3 Series can now enjoy wireless Android Auto technology as a standard item. The other high-level features that are standard or available in the 3 Series are found in both model years. A few of these are Apple CarPlay, leather seats with climate controls, a navigation system, an advanced audio system, a personal assistant, a keyless ignition, and other gear.

The BMW of Milwaukee North sales reps are ecstatic about the improvements found throughout the 2021 3 Series. Are you eager to get more familiar with them through a test drive soon? Make arrangements for your upcoming test drive by contacting BMW of Milwaukee North’s sales team today.
