M4 Cabrio Competition Package
In February 2016, BMW announced the M4 Competition Package. The M4 Competition Package increases power output by 14 kW (19 PS; 19 hp) to 331 kW (450 PS; 444 hp) and has a revised suspension for better handling. New springs, dampers and anti-roll bars complement the included Adaptive M Suspension. BMW also re-tuned the electronic differential and the Dynamic Stability Control to match the upgraded hardware.
The interior remains largely unchanged, but Competition Package cars get new lightweight sport seats along with the M-striped woven seat belts. The exterior includes the M Sport exhaust with black chrome tailpipes and high gloss Shadow Line exterior trim. Gloss black trim is added to the kidney grille, side gills, and model badge on the trunk.
With the Competition Package, the coupe version accelerates from standstill to 100 km/h (62 mph) in 4.0 seconds.
There is a convertible version, and that does the run in 4.2 seconds, both coupe and convertible forms using the dual clutch transmission.
