Earlier last week, Washington Post journalist Drew Harwell wrote a detailed post about the state of “fake” engine noise found in today’s new cars. There are a number of different acronyms for this technology across the industry, but the BMW Group calls it Active Sound. In fact, MotoringFile readers are quite familiar with its mechanism as we covered the topic about a year ago.
From what I understand, the existence of Active Sound is motivated by two main factors. The first one being progress in engine technology. Due to fuel efficiency goals, it’s just not possible to build motors that are both efficient and that provide a nice rumble noise through the cabin. The second factor is the customer’s desire to be more insulated from road noise. However in sporty cars there’s still a desire to be able to hear the engine thus automakers have created a way to take that sound and digitally amplify it.
Unfortunately, purists can complain all they want but this seems to be a necessary evil. To be honest, I’m not a fan Active Sound either but I’d rather have this than no engine sound at all. How do you feel about it?
