The all-new M3 came out as a 2015 model year and will now be available only as a 4-door sedan. Gone is the V8 under the hood, and has been replaced by a highly-tuned twin-turbocharged inline-6, mated to either a 6-speed manual or a 7-speed dual-clutch automatic. Features include head-up display, a backup camera, parking sensors, ventilated seats, keyless entry, and headlamp washers. The Driver Assistance package adds blind-spot monitoring, lane-departure warning, autonomous braking, and side-view camera.
