Here’s the latest form of tying the radio to car functions. The 2012 BMW M5 car radio mimics the sound of the car’s engine revving and whining as you drive.
BMW apparently had to keep the engine noise (external) to legal guidelines but didn’t want drivers to miss the sweet roar of acceleration. So it tied the DSP of the sound system directly to the engine management system, “allowing it to reflect the engine’s revs and torque, and the car’s speed over the road,” said page 34 of a 47 page press release for the car that will formally debut in a few months at the Frankfurt Auto Show.
