Neither major U.S. safety rating organization has crash-tested an M3 yet, and we don't expect that to change much either. The IIHS and NHTSA haven't thrown an M3 into a wall, but the structurally similar 3-Series netted a four-star score for front impact safety and five stars for side-impact safety from federal testers. The IIHS gave the 3-Series a "Good" rating, and Edmunds noted the excellent outward visibility from those cars.
Before hitting a wall, Cars.com noted the M3's big disc brakes that can help stop the car. With 14.2-inch rotors up front and 13.8-inch rotors in rear, the M3 has the stopping power to bring the sport sedan to a halt. The M3 also features standard stability and traction control systems.
According to Edmunds, the 2009 BMW M3 offers a comprehensive safety package, including "full-length side curtain airbags, front seat side airbags [and] antilock disc brakes.”
