Mercedes-AMG A45 & CLA45 exhaust sound restricted by European regulations

Mercedes-AMG has been forced to cut back the exhaust theatrics with its new A45 and CLA45 to meet ever-toughening noise and emission regulations in Europe, cuts Mercedes-Benz says apply to all markets including Australia. The new A45 and CLA45 make use of the world’s most powerful 2.0-litre production engine delivering an impressive 310kW of power and 500Nm of torque, good for a 0-100km/h time of 3.9 seconds in A45 S hatchback.
