BMW has ramped up the performance of the M3 saloon, M4 coupé and M4 Cabriolet with the introduction of a new competition package, providing the M-car trio with greater power and enhanced acceleration as well altered suspension and a series of subtle styling changes.
Set to be included on a limited run of 30th anniversary models planned for sale in the UK, the new competition package endows the M3 saloon, M4 coupé and M4 Cabriolet with an added 19bhp through unspecified tweaks to their twin-turbocharged 3.0-litre in-line six-cylinder petrol engines, raising output from a standard 425bhp to a new peak of 444bhp. Torque remains the same at 405lb ft.
BMW claims the mild increase in power contributes to a 0.1sec lowering of the 0-62mph time of its various M3 and M4 models.
This gives the competition package-equipped M3 saloon and M4 coupé a 0-62mph time of 4.2sec in manual form and 4.0sec in combination with the optional seven-speed M DCT dual-clutch automatic gearbox, with the M4 Cabriolet recording respective figures of 4.5sec and 4.2sec.
