BMW realized that the pathetic noise of a diesel-powered engine is a negative when it comes to driving fun! So they’ve come up with a cunning plan to produce fake V8 petrol noise. As you see in this video by Autocar, they’ve tried this Active Sound Design system on a four-cylinder diesel MINI. They’re also developing a similar system for BMW 6-series diesel. It’s a bit lame, but it’s better than hearing the diesel noise anyway!
