The BMW 428i, despite being built on the same platform as the 328i, and carrying the same engine under the hood, feels somewhat different on the road.
The main difference between the two vehicles is that the BMW 328i is a 4-door sedan, whereas the BMW 428i is a 2-door car. If you want a sporty ride, pick the 428i. If you want a good all-round BMW, the 328i is a better value.
General comparison of the BMW 328i and BMW 428i
Despite being a 4-door coupe, the BMW 328i is slightly smaller than the BMW 428i. It is also a lot taller, which means it provides a lot more headroom for the passengers in the back. That makes the 328i way more suitable for a family. Of course, having back doors also helps a great deal, as constantly having to push backrests forward might be a nuisance for every 428i owner.
If you have a baby and need to install a baby seat in the back, the BMW 328i should be your go-to choice, since the BMW 428i makes it almost impossible to do so.
Another great argument in favor of the BMW 328i is that BMW 428i’s doors are very bulky and might be hard to fully open next to other cars. If you live in a densely populated area and you have trouble finding a parking spot, the BMW 328i is a better choice.

Engine and driving experience
The two vehicles operate with the same exact engine and the same wheelbase platform. The main difference in terms of driving experience between the two is the fact that the BMW 428i is a lot lower than the BMW 328i, making it better positioned on the road, with a sportier feel.
The BMW 428i feels more aggressive, not only on the outside, but also in terms of driving. Both vehicles can be equipped with a 6-speed manual transmission and an 8-speed automatic.
The BMW 428i features frameless door glass and much lower rooflines, which gives it a sportier and sexier look overall. The front lights look more aggressive, and the grille is slightly larger.
The other main difference of exterior is the 2 and 4-door difference. Internet reviews and statistics show that although many people have decided between these two vehicles, the majority often picks the 4-door BMW 328i for the comfort it provides. Having a 4-door vehicle can be a great advantage. Even if you are living alone, it might help packing up some luggage in the backseat.
Interior & features
Talking about the interior, the BMW 3-Series usually comes with a standard full-color head-up display that allows you to drive without taking your eyes off the road if you need to check on the infotainment system. Whereas, in the BMW 4-Series models this is an optional add-on.
On the other hand, the BMW 428i comes with a sunroof as a standard, which is optional if you decide to choose the BMW 328i.
Both vehicles are equipped with the standard blind-spot detection sensors, cruise control, and active driver assistance. Rear cameras and parking sensors are also standard in these models. The two models also have adjustable seats and steering wheels, as you would expect from high-end BMWs.
The final verdict
If you prefer driving on your own and you are looking for a sportier, more aggressive-looking vehicle, the BMW 428i would be the better choice for you. That is, of course, if you do not mind driving a 2-door car.
The BMW 328i, on the other hand, still boasts the same power under the hood and is quite fast. At the same time, it allows you to be able to carry passengers and luggage comfortably. It is a much better choice for families or drivers who often drive around with more than one passenger on board.
