As we’ve previously reported, BMW will likely begin distinguishing coupes and convertibles from sedans by using even and odd numbers. Thus, the former 3-Series Coupe will become the 4-Series, while the old 1-Series Coupe becomes the 2-Series.
The same holds true on the crossover and SUV side, sort of. The X3, for example, is a conventionally styled, box-on-box, four-door crossover. The upcoming X4, on the other hand, gets four doors but is styled like a coupe. Confused? Just think of the difference between the current X5 and X6 models, but on a slightly smaller scale.
If Car and Driver is correct in its prediction that the 4-Series will debut in Detroit, expect the concept coupe to appear in near-production form. The styling will be applied to both the coupe and the upcoming convertible, which will also be marketed under the 4-Series banner.
As for engines, don’t expect any changes from the current offering in the 3-Series range. Base 4-Series models will get a turbocharged 2.0-liter four-cylinder, while the higher-output models will benefit from a turbocharged 3.0-liter in-line six-cylinder. Eventually, there will likely be an M4, too.
We’ll help you sort this out in more detail as soon as additional information is available, and we’ll be on hand in Detroit to cover all of BMW’s new model introductions.
