Serving Milwaukee, WI

At BMW of Milwaukee North, our valued customers searching for a smaller car packed with great features often ask us about the differences between the 3 Series and the 4 Series. The 2023 BMW 3 Series sedan stands notably apart from the 4 Series convertible and coupe. A closer look at the possibilities can help you to narrow your range of options as you prepare to make a final selection.


The base trim for the 2023 3 Series receives 225 horsepower from a four-cylinder turbo engine. The middle trim option benefits from 288 combined horsepower produced from a PHEV turbo four-cylinder system. The highest trim level has a V6 turbo, a mild-hybrid powertrain that puts out 382 combined horsepower. If you prefer to drive the 2023 4 Series, you can choose from two powertrains. The lower trims pull 255 horsepower from a four-cylinder, 2.0-liter turbo unit. The top trims draw 382 horsepower from a V6, 3.0-liter turbo system.


The 2023 3 Series is beautifully styled with strong curves through the hood and roof. This is paired with refined contours and a deep accent line on the sides. At the front of the 3 Series, the small, wide grille has a two-part, kidney-shaped design. Angled headlights, double LED light ribbons, and prominent air vents complete the look. The design of the 4 Series is boldly different. It shows off its individualized, athletic style with a strong fender definition and a bent accent bar through the sides. The tall, two-part grille covers the nose from top to bottom. Its narrow width allows for significant air intake and lean headlights with a double LED light element.


Regardless of the model selected, you can appreciate numerous advanced features. Both models are offered with wireless smartphone connectivity, active lane-keep, a digital panel for the driver’s instruments, evasive steering assistance, keyless door entry, active cruise control, heated front seats, a heads-up display, and more. Each model has a few unique features as well. For example, the 3 Series has a curved central display screen, and the 4 Series comes with a premium Harman Kardon audio system.

While both models have impressive capabilities and features, one option may immediately stand out to you now that you know more about them. To finalize your model research, make plans to visit BMW of Milwaukee North to explore the 3 Series and 4 Series in person.
