The CFC-free automatic climate control in the M6 Convertible is capable of independently regulating the temperature in the rear passenger compartment and the cockpit. But air not only has to be at a pleasant temperature, it has to be clean as well. Automatic Air Recirculation (AUC), fitted as standard, detects pollutants in the air outside, such as carbon monoxide, nitrogen oxide and ethanol, and ensures that they do not enter the vehicle.
