The M3 is a legend in the world of performance cars, causing enthusiasts to gush when given the chance. Under the hood is a twin-turbo 3.0-liter inline-six that makes 425 hp and 406 lb-ft of torque; it makes glorious sounds all the way to its 7500-rpm redline. For more power, the Competition package offers 444 hp and 20-inch forged wheels. A six-speed manual is standard and a seven-speed dual-clutch automatic is optional. The M3 comes only as a sedan; coupe and convertibles wear the M4 badge.
