Quietest Subcompact Ever?

[Aglie]

My wife has a Matrix, which has Toyota's ubiquitous 1.8L engine and a 5-speed. Engine noise (or lack thereof) is pretty similar, but there is way more wind noise even at 30-40 mph. I think the Fiesta may have less road noise too but that's less obvious than wind noise.

So, I've heard both my car and hers from outside, and the Matrix is way louder from outside.
