The 'M3 CS' special edition was produced in 2018 with an upgraded engine rated at 339 kW (454 hp) and 601 N⋅m (443 lb⋅ft). The official 0–100 km/h (0–62 mph) time was 4.0 seconds with the dual-clutch transmission. Changes included an increase in power to 331 kW (444 hp), revised tuning of the electronic differential and the electronic stability control ('DSC'), suspension upgrades and new front seats. In 2016, a Competition Package became available for the M3 and M4.
The F80 M3 was unveiled, alongside the F82 M4 (its coupé counterpart), at the 2014 North American International Auto Show. Top speed is limited to 250 km/h (155 mph) but an optional M Driver's package raises this to 280 km/h (174 mph). The official 0–97 km/h (0–60 mph) acceleration times are 3.9 seconds with the M-DCT transmission and 4.1 seconds with the manual transmission. Despite the smaller displacement than the V8 engine used by the previous generation of M3, the switch from naturally aspirated engines to turbocharging resulted in peak power being increased from 309 to 317 kW (414 to 425 bhp), and peak torque being increased from 400 to 550 N⋅m (295 to 406 lb⋅ft). The F80 M3 was powered by the BMW S55 twin-turbocharged straight-six engine, therefore being the first turbocharged M3 model. The M3 version of the F30 3 Series was designated the F80 and was produced from 2014-2018.
