BMW 320i vs 320d

BMW’s most popular models are the 320i and 320d, which are very close to each other in appearance. Although their designs are similar, there are some differences between these two popular models with thousands of drivers today. From technical details to economic features, the 320i vs 320d has several differences. Just like the BMW 320i vs 328i, the differences here are not too dramatic.


The engine is the most essential component of a car and there are some differences between 320i and 320d in terms of engine specifications. Both the 320i and 320d have a 2.0-liter four-cylinder engine. While the 320i offers a balanced engine specification in terms of performance and energy efficiency, the fuel efficiency results are much better in the 320d. Generally, 320d models have a diesel engine and this offers more efficient solutions in terms of the budget.


Performance is one of the most significant matters in car comparisons. It is known that there are some differences in performance for 320i vs 320d. Among BMW’s two most popular cars, the 320i offers respectable acceleration and power delivery. This makes the 320i a better option for daily driving. However, the 320d offers better results in long-distance driving. Under similar conditions, both models deliver similar performance results.


Just as with the 328i vs 330i, the difference in transmission between these two models is not quite as striking. While 320i has standard transmission systems that come with manual and automatic options, this is also the same for 320d. Since the 320d has a diesel engine, the transmission system is designed to be compatible with this function. However, in tests carried out under comparable conditions, it can be said that the shift quality results of both are similar.


Suspension is one of the features that should be included in car comparisons. If a car has a bad suspension system, your driving experience will be very badly affected. There are some differences between 320i and 320d for suspension. In the 320i models, the suspension units are not suitable for use purely for sportiness, but the comfort factor is also considered when designing. In the 320d model, the suspension systems offer a successful handling and ride quality. Considering that the diesel engine in the 320d is heavier, it can be said that the suspension of the 320d is more powerful.


BMW is a manufacturer that has proven its quality in brakes systems. The most popular models of the BMW, the 320i and 320d, also have advanced brakes. It can be said that there are some differences between 320i and 320d in brake units.

The fact that the 320d has slightly more advanced brakes contributes to the drivers’ car control and driving pleasure.

The 320i model has an excellent fuel efficiency technology, even though it varies according to different variants. Thanks to the gasoline engine in the 320d model, excellent results are obtained in terms of fuel efficiency. Especially among the driver profile that uses such older models, fuel efficiency is a priority subject. We can state that the 320d will meet the expectations of such drivers.
