Whether it’s the coupe or the sedan, the 2009 BMW M3 makes its thundering performance known with bulges, vents, slits, and badges.
Car and Driver observes the 2009 BMW M3’s “bulging aluminum hood” and says “visually, there's no confusing the M3 with a standard-issue 3-series, even though both cars share doors, windows, headlights, taillights, and trunklid.” The other panels have been massaged, and BMW replaces the normal steel on top with a "carbon-fiber roof," says Cars.com; it’s the "the flared fenders and nose-low, hunkered-down profile that suggests a nearly audible snarl." Autoblog points out the "M-specific quad pipes" that "let Bimmer cognoscenti know that they're behind something special." "The BMW M3 appears as a 3 Series Coupe or Sedan that's been to the gym," explains MyRide.com, "not like a dude on 'roids but rather someone who's been doing twice-a-days and eating nothing but chicken and tuna." The front and rear fascias are "revised," the hood has "rippled aluminum" with vents, plus "additional vents on the fenders," they add, summing up its styling as "an exquisite machine that doesn't require exaggerated body kits to draw attention." Edmunds agrees that it has “more aggressive body styling” than the usual 3-Series coupe or sedan.
"Heavily-bolstered," the seats "feel custom-made to your body." Plus, the "thick-rimmed steering wheel" gives the driver a "sporty feel," while cruising down the highway. Additionally, "leather trim" and "door sills with the M logo" round out the interior of the "high-performance" M3 BMW, says MyRide.com, with the added comfort typically left out of such sporty vehicles.
The interior of the M3 has changed, but not as dramatically as the exterior, Car and Driver noted. The M treatment applies with sportier buckets and a thicker steering wheel, and M badges all around the car. Edmunds noted the front seats as being particularly "aggressive" in the M3.
