Rolls-Royce Spectre
Why 3.8: The quietest car from the company that invented quiet as a selling point — electric drive completing a century-old brief. Pure arrival theatre; the Cullinan's coupé soulmate at the floor of the index.

Sound
Rolls-Royce did commission a faint composed note, then spent far more effort deleting everything else, because the absence is the product. But that leaves a car whose defining acoustic quality is that there is nothing to hear. Barely above the silent EVs.

The long version
Buyers choosing the coupe over the Cullinan are picking style over practicality on purpose, which says something about how little the powertrain factors into the decision — electric or twelve-cylinder, the brief was always silence and presence, and Rolls-Royce delivered both without the ownership base asking many questions about range or charging. It arrives at the same hotel entrances and gala valet stands as its SUV sibling, just with two fewer doors and a lower drag coefficient nobody in the back seat will ever notice. The electric drivetrain is a footnote to a purchase that was never about the drivetrain.
