We can confirm that there’s been no boost in output for the M4 which remains down on power compared to rivals such as the Cadillac ATS-V Coupe and Mercedes-AMG C63 Coupe. The car’s familiar turbocharged 3.0-liter inline-6 continues to deliver 425 hp as standard and 444hp with the available Competition Package.
