September 27, 2011 – Irvine, Calif. - Irvine BMW is excited to confirm, The Active Sound Design technology will bring the M5 engine sound directly into the cabin.


The Active Sound Design technology specially developed for the new BMW M5 takes its cues from the driving situation at any one time to deliver an accurate reproduction of the engine’s sound through the car’s audio system.


“This sort of technological addition shows that BMW is capable of doing some amazing things,” said Darren Richie, General Manager.  “This will really showcase the “power” of the M5.”
     

The system’s digital signal processing exchanges data directly with the engine management, allowing it to reflect the engine’s revs and torque, and the car’s speed over the road. The result over a smoothly driven journey is a discreet soundtrack in keeping with the harmonious and assured characteristics of the V8 powerplant. A stamp on the accelerator, meanwhile, prompts an immediate audible response to match the instantaneous – and typically M – burst of power from beneath the bonnet.
     

In generating its signals, Active Sound Design takes its cues from the firing sequence of the eight-cylinder engine and the frequency range of the exhaust system. This gives the driver an extremely accurate impression of current engine load and an even more intense sensation of the V8’s high-performance characteristics. At the same time the Active Sound Design control unit ensures an even spread of sound across all five seats of the new BMW M5, while observing the legal guidelines governing noise emissions inside and outside the car. The characteristics of the sound produced by the technology also adjust to the engine settings selected by the driver. For example, switching to “Sport” or “Sport+” mode sharpens not only the engine’s responsiveness but also the acoustic experience inside the car.
