I do take your point, but Lambo have always been about theatre. The posters may not have had a speaker in them but you knew they sounded amazing. When you see one in person, especially if the driver is in the mood to give it a stab, surely one of the first things you say is "listen to that thing!"

Their image is about being extreme in every theatrical way, and I can see how a bullshit-fast but near-silent Lambo might not appeal to the vast majority of their customers. And ultimately if they're only going to sell a small handful then it's not worth their while to build them at all.

My sister's husband has a 400hp Audi and in my opinion it's much more fun car than an electric one with double the power. Objectively better isn't always what people actually desire. A digital watch for example is less desireable than a mechanical one despite being better at accurately and reliably telling the time.
