The Verdict

Many people can’t tell the difference between the BMW 3 Series and the BMW 4 Series. In this article, we have tried to tell the difference and we conclude by saying, the BMW 3 Series has a sportier 2-door coupe, 4-door gran coupe, and convertible siblings by the name of  BMW 4 Series. But although they have similarities, they also have enough differences to justify the name change. Unlike the 3 Series, the 4 Series comes fitted with a top-drawer engine with great performance, fuel economy, with some great rear-wheel-drive handling. 

As part of  BMW’s range expansion plan, the 3 Series Coupe and Convertible were extended by providing the Coupe, Convertible, and Gran Coupe models and gave them the BMW 4 Series name signifying their sportier nature.
