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.
For the Competition Pack models, BMW has tweaked the Adaptive M Suspension, stability control and Active M Differential. New springs, dampers and anti-roll bars are fitted, and the driving experience modes (Comfort, Sport and Sport+) have been recalibrated. The 20-inch alloy wheels are a star-spoke design with 265/30 R20 tyres at the front and 285/30 R20 at the rear.
“With more power, enhanced suspension and bespoke settings for the differential and stability control systems, the Competition variants are aptly named,” he added.
Pricing starts at $144,900 for the M3 Competition sedan, $154,900 for the M4 Competition coupe and $165,900 for the M4 Competition convertible. All pricing is before on-road costs.
