What will the M6 look like?
The answer is very easy. Just looks at the differences between 5 Series and M5, and you'll se what will be the differences between 6 Series and M6.
Usually an M car gets a special body-kit, one that is completely different from the rest of the line up. Take the example of the 3 Series Sedan E90:
- BMW 3 Series
- BMW 3 Series Performance
- BMW 3 Series M Package
- BMW M3
All these cars have completely different front bumpers, side skirts and rear bumpers. However really very different parts between the 3 Series Parformance and the 3 Series M Package are only the front bumper. The side skirt is has exactly the same desing, it only has a an added air inlet at the back. The rear bumber is also exactly the same, only the diffusor changes, it gets some tipe of fins.
When somebody puts an M car body kit on an non-M car, it is just a wrong thing to do, plus to being quite difficult, as the M3 for example has also different fenders, so that changing bumpers and side skurt is not enough.
However now, it seams M has taken the same direction. Now an M car would simply be an M-package bodykit with just another front bumper.
See for yourself:
The front bumper of course is different. But then, the side skurts and the rear bumber are the same. The only difference is the rear diffusor, which is a small unscrewable part of the rear bumper.
No we can go over to M6.
The side skirts and rear bumper will be the same. Only expect the diffusor in M5 style. Then add the M5 mirrors and an M letter on the side gills, just as the previous generation. The rims are the same. THe only thing left to know is the front bumper, well that is because it is the only DIFFERENT part of the bodykit.
All in all, it will not cost much to convert you 5/6 Series M Package into M5/M6 look, only change the front bumper, find a rear diffusor.
Unfortunately it seems, in the coming years, for an M car, you'll pay alot more, for very little more.
