The BMW M3 is a high-performance version of the BMW 3-Series, developed by BMW's in-house motorsport division, BMW M. The "M" on M3 stands for Motorsport, which linked indirectly to how the car's overall driving model is, motorsport-like. BMW M3 Coupe is a 2-door version of the M3. The M3 Coupe featured on GRID 2 is the one with E92 model number. The E92 was first teased by BMW on the 2007 Geneva Motor Show located in Geneva, Switzerland, as a concept. The concept looked (and really is) the same as the production version.
The BMW M3 Coupe will be unlocked for purchase upon reaching Level 9, and is featured on Tier 2.
