Following the M car formula, the 1M features increased power, a manual transmission, rear-wheel drive, a modified suspension, fat tires and a distinctive look — perhaps more distinctive than the other Ms. The car's track is 2.8 inches wider in front and 1.8 inches wider in rear than the regular 1 Series, so the fenders have swollen as well, resulting in an exaggerated, almost cartoony style that might appeal to some BMW fans — and turn off others. Familiar 19-inch alloy wheels are shared with the M3's optional Competition Package.
