Hello all,
A little introduction! I currently live in-between two countries, USA and Indonesia. So, I own several cars right now, including F10 BMW 535i, G30 BMW 540i, G30 BMW 530i, W212 Mercedes-Benz E400, among other cars.
Out of my own curiosity, I've conducted several (un)scientific experiments in some of my cars at 100 km/h, ac on low with no music on. For all of these, I put the measuring device right at my eye level in all of the cars. It just seemed that my BMW 530i is a lot quieter than the other cars, and seems that this experiment proves it. Thought it was iinteresting and I wanted to share.
