BMW’s numbering system for its models will be expanded. Next year, BMW will launch a coupe named the 4 series. After a few years, the 2 series (a new number) will arrive. The roles of the 2 series and the 4 series will be similar. Both are meant to boost the brand image of the automaker. The coupe and cabriolet variants of the mainstream sedans will cost higher so that they would win higher resale values.
The odd numbers will be maintained for BMW's sedans and hatchbacks, the 1 series, 3 series, 5 series and 7 series, as well as the X1, X3 and X5 SUV/crossovers. The even numbers will still be used for the sportier SUV/crossovers in any BMW size class. In 2014, the X6 will be joined by the smaller X4. A more compact X2 will come later.
The 4 series will be the replacement for the coupe version of the 3 series, which made up around 10% of total 3-series sales in 2011. What BMW intends to do with the 4 series is to give its top-selling coupe its own identity. When the 3 series was released in 1975, the two-door variant used a design that’s similar to that of the four-door.
The two-door received styling in 1991 that distinguished its side view from the four-door. It was given the 3-series coupe name too but it remained to be a close relative of the 3-series sedan in its front styling and basic underpinnings.
The 4 series uses a bigger chassis, lower roof and a completely independent personality. This coupe also boasts striking looks. It was also announced that the M4 will replace the super sporty M3. BMW has yet to unveil the details about the powertrain for the 4 series but it’s likely to have a V8 engine, judging by the length of the 4-series concept that will make its debut this January at the Detroit Auto Show.
