I realize that, but when I was at the Team USA event, the dealer had a 335d and X5d. Sitting in the 335d, it was aurally quite nice, couldn't tell I was in a Diesel. However same drive in the X5d, the idle speeds indicated I was in a diesel, whereas highway speed i couldn't tell the difference.

This isnt a just one time thing, many others have posted similar experiences, and I think Mike aka Emissions had some good points about how the injectors on the X5d dont have any isolation material and the space where the engine is much more larger and thus emptier allowing to act like a acoustic chamber

Why does this matter?
CAUSE EVERY TIME someone says Lexus has better build quality, one should consider what Toyota their Lexus Engine and chassis platform comes out of and how long that part has been tested in the real world!
