There's anadditional noise encapsulation panel underneath the car, and it has an insulative blanket affixed to it; also, the interior carpet is D-specific, I believe with more sound deadening material. Also, there are a lot of small insulated pieces throughout the nose of the car-the motor's sealed pretty darn tight.
