The M3 has evolved over time from a racing homologation car into a full-fledged lineup unto itself. The newest M3 has already debuted in coupe and sedan form, and both are bona fide winners. Like the coupe and sedans, the M3 convertible comes with a 4.0-liter V-8 pushing 414 horses at a lofty 8,300 rpm, and 295 lb.-ft. of torque at 3,900 rpm. The new über Bimmer also boasts a six-speed manual transmission, locking differential, an aluminum chassis, electronic damper control, cross-drilled cast iron rotors, and Servotronic steering with Normal and Sport modes.
