Faster and promising a sharper drive, the BMW M3/M4 Competition Pack arrives locally priced from $144,900 plus on-road costs.

There is a $10K jump from Competition Pack sedan to the $154,900 coupe and another $11K to the $165,900 convertible, each commanding a $5000 premium over the standard M3 sedan and M4 coupe/convertible models.

That surcharge buys an extra 14kW from the 3.0-litre twin-turbo six-cylinder engine, which now produces 331kW (although 550Nm is unaltered) to deliver a claimed 4.0sec 0-100km/h, a tenth faster than the regular M3/M4.

The Competition Pack also swaps out the standard 19-inch alloy wheels for machine-finished multi-spoke 20s, with 265/30 front and 285/30 rear rubber offering 10mm extra tread width, “to deliver improved handling characteristics”.

BMW further claims a new calibration for the active M differential “aids drivability and traction” while the adaptive suspension has been reconfigured in each of its three modes to match revisions to the three-step stability control.

Primary changes inside include new leather-trimmed electrically adjustable front buckets “that use distinctive cut-out elements to reduce weight” and M stripes stitched into the seatbelts.

The M3 and M4 Competition Pack is clearly designed to more closely challenge the Mercedes-AMG C63 S and the $162,400 coupe’s 3.9sec 0-100km/h.

Time will tell if the Competition Pack models can keep tough competition at bay.
