BMW has developed a new system for its latest high-end M5, called Active Sound Design. The system will play engine sounds through your car stereo, and the system takes the engine speed and load data from the ECU and then plays a real-time recording of the M5 engine through the car stereo.
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. 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.
Understanding Active Sound Design
Active Sound Design (ASD) is an innovative technology that aims to enhance the driving experience by providing an auditory representation of the engine’s performance. This system is particularly beneficial for high-performance vehicles like the BMW M5, where the engine’s sound is a crucial part of the driving experience. By using the car’s stereo system to play engine sounds, ASD ensures that drivers can enjoy the full auditory experience of their vehicle, even if external noise or soundproofing might otherwise dampen it.
The system works by taking real-time data from the car’s Engine Control Unit (ECU), including engine speed, load, and other performance metrics. This data is then processed and converted into sound, which is played through the car’s audio system. The result is a dynamic and responsive sound experience that mirrors the car’s actual performance.
Benefits and Applications
One of the primary benefits of Active Sound Design is that it allows drivers to enjoy the full auditory experience of their vehicle without the need for aftermarket modifications. Traditional methods of enhancing engine sound often involve installing louder exhaust systems or other modifications, which can be expensive and may not be legal in all areas. ASD provides a legal and cost-effective alternative that can be easily integrated into the car’s existing systems.
Another advantage of ASD is its ability to provide a customizable sound experience. Drivers can choose different sound profiles depending on their preferences or driving conditions. For example, a driver might prefer a quieter, more subdued sound for city driving, but a louder, more aggressive sound for highway driving or track days. This flexibility allows drivers to tailor their driving experience to their specific needs and preferences.
Moreover, ASD can also enhance safety by providing auditory feedback that can help drivers better understand their vehicle’s performance. For example, the system can provide audible cues when the engine is under heavy load or when the car is approaching its performance limits. This can help drivers make more informed decisions and avoid potentially dangerous situations.
We are not exactly sure why you would want this feature, although we suppose it could be fun to listen to engine sounds through your stereo if there is nothing decent on the radio. However, for car enthusiasts and those who appreciate the auditory experience of driving a high-performance vehicle, ASD offers a unique and valuable enhancement.
In conclusion, BMW’s Active Sound Design represents a significant advancement in automotive technology, providing drivers with a more immersive and customizable driving experience. By leveraging real-time data from the car’s ECU and using the car’s audio system to play engine sounds, ASD offers a legal, cost-effective, and flexible alternative to traditional methods of enhancing engine sound. Whether you’re a car enthusiast looking to enhance your driving experience or simply someone who enjoys the sound of a powerful engine, ASD is a feature worth considering.
