Listening for Quality

I had the chance to conduct an impromptu evaluation of cars going up a slight hill. I listened for quietest engines. I asked myself the question, “Do I hear tires rolling on pavement or an engine roaring above the tires?”

Top cars with quiet engines were:

-> Honda (always)
-> Toyota
-> Mercedes (gasoline)

The loudest engines climbing the hill were consistently American brands and an expensive Porsche. They roared audibly over and above the grind of tires on pavement.

Interestingly, the louder the engine, the more exhaust fumes left behind to irritate the nose.
