&quot;I didn&#x27;t realize these modern diesels still sound terrible, are they really that bad?&quot;<p>You know the somewhat recent Jetta TDI (2.0 ? 1.8 ?) that&#x27;s really, really loud ?  They&#x27;re not quite that bad.  But they&#x27;re loud, and the loud they make is an antique loud.  A non-precision loud.  Noises that nice new luxury cars shouldn&#x27;t make.<p>I am in europe regularly for rsync.net and the diesel A6 and A8 (among others) are not any better.<p>It&#x27;s really just a terrible aesthetic.  I don&#x27;t know why people put up with it.
