M package includes new trims for the inside and out but likely no engine upgrading. In the leaked photos we get to see much of the exterior package.
Here are some leaked photos of a BMW X1 fitted with the M package accessories.
Likely, though, this is just a body kit with no engine performance upgrading involved. However, the new 2.0 liter turbo 4-cylinder petrol/gasoline engine in the X1 xDrive28i would be a good match.
But the cosmetic changes are noteworthy. There are new bumpers, wheel arches and front-spoiler with a mesh-grilled vents.
Additional interior trim also seem to be part of the package including the sport steering wheel and the M-badging door sills. Part of the package is an M-gear shifter which we can't really make out with the one interior shot here.
The M package for the wildly successful X1 is likely to be announced very soon.
