In all body types - M3 sedan, M4 coupe and convertible - BMW M has raised power from 317 to 331kW, bringing the trio a smidge closer to the Mercedes-AMG C63’s 350kW and 375kW tunes. (Australia gets only the latter.)
The upgrade shaves 0-100km/h acceleration for the M3 sedan and M4 coupe from 4.1 to 4.0 seconds, and the M4 convertible from 4.4 to 4.3 seconds.
Upgraded Active M suspension is also fitted, packaging new springs, dampers and anti-roll bars, along with tweaked Comfort, Sport and Sport+ driving modes. Those tricks are joined by upgrades to the Active M differential and dynamic stability control.
At the corners are “forged, machine-polished, weight- and rigidity- optimised” wheels, measuring 20x9-inch at the front and 20x10-inch at the rear. The tyres are likewise staggered, with 265/30s at the front and 285/30s out back.
Styling enhancements include black exhaust tips and the ‘Shadow Line’ trim finish, which adds a high-gloss black to the side window trim, window recess finishers, mirror frames and bases, grille, side gills and model badge.
Lightweight M sports seats feature in the cabin, matched to seat-belts with woven-in BMW M stripes.
Australian availability for the Competition Pack models is still to be locked in, although BMW Australia communications manager Lenore Fletcher confirmed with CarAdvice today that the local arm is keen to get all three variants to Australia.
