BMW changes the sound of the M3 and M4 through a software update


Here’s another reminder of today’s modern digital cars. BMW car just announced that they are sending software updates over-the-air to BMW M3 and M4 that will change the way they sound.

Of course, this software update doesn’t affect the noise coming from the M’s quad tailpipes. Instead, it’s the software that changes the synthesized sound played through the cabin speakers.

We suspect that M3 and M4 Owners are wondering how this update will change their cars, and BMW provided us with a short description of what’s happening. BMW says owners “will be inspired by the fine tuning of the engine start-up sound.” We’ve asked BMW exactly what that means – and will update when we get an answer – but our best guess is that the initial launch will be noisier and more dramatic than before. The M3The launch of the Hellcat isn’t exactly quiet, but it’s not the roaring Hellcat either.

Additionally, owners of Competition models with the eight-speed automatic will find “a clearer confirmation sound on shifting and shifting shifts”. We suspect that the clearer shifting sound means that each shift is accompanied by a louder bang. The current sounds almost like a loud bang, making it hard to believe that people are missing the lifts or want a larger transition. No problem, we’ll follow up in the next M3 or M4 that we drive to hear the difference for ourselves.

Besides the above, there are other updates to the entire BMW lineup, as long as BMW is equipped iDrive 7. The lane departure warning system will use new logic that is said to be able to detect if it is on a narrow road without a center line. If this is the case, the car will automatically prevent steering intervention to make sure it doesn’t steer toward the middle of the road (potentially oncoming traffic) if you move into or over the line. side line.

The navigation system is improved for better congestion detection and will provide you with further optimized routes. BMW Digital Key functionality (using your phone as a car key) extends the functionality of the Samsung Galaxy S21 and Google Pixel 6 and 6 Pro phones. The BMW News app has been upgraded with higher sound quality and more personalization options. Ultimately, updates to the Spotify and Sirius XM Pandora apps will make both of those services a better user experience – both simply adding more capabilities and options in their respective apps. response.
