Although the 2009 BMW M3 hasn’t been crash-tested by either the Insurance Institute for Highway Safety (IIHS) or National Highway Traffic Safety Administration (NHTSA), Edmunds notes the similar 3-Series BMW scores four stars for front-impact safety and five stars for side-impact protection from NHTSA, while the IIHS gives it a “good” rating. The M3 BMW also "offers good visibility and an excellent driving position," adds Edmunds.
The large four-wheel-disc brakes can abruptly stop the BMW M3, says Cars.com. To be specific, the "14.2-inch rotors are used up front, while rear rotors measure 13.8 inches," plus "antilock brakes and an array of assist programs, including BMW's Dynamic Stability Control, are used."
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.”
