Are you ready for another big piece of BMW naming scheme news? Not long after the BMW M2 was released, we got news that the M235i would become the M240i. However, this is far from the only change to BMW's already confusing lineup. In conjunction with the name change, BMW's four-cylinder models will get a new 2.0-liter turbo engine, called the B48, to replace the old N20. The six-cylinder models will be getting a new engine called the B58 which will replace the N55. If you aren't confused yet, wait until you hear about the name changes.

At first, the name changes will effect all 2, 3, and 4 Series models. Four-cylinder models will be known as the 230i, 330i and 430i while six-cylinder models will be called the M240i, 340i, and 440i. These changes will affect all body styles of these cars, including wagon and Gran Coupe variants. These changes are pretty easy to follow, but the information gets really messy when you get to the bigger cars. The 540i, 640i and 740i will continue to use the last-generation six-cylinder and we still have no idea about BMW's crossovers. Good luck keeping track of BMW's name changes. Frankly, we all might as well give up.
