The manufacturers are very social media savvy. They look out windows until photographers are present outside the plant gate and they drive a lightly covered car through the only area in the plant where it can be photographed.
This will be endlessly promoted and speculated upon for the two weeks of the holidays. After which, say, in mid-January, there will be additional shots of this car out on a highway, probably near a majestic mountain pass.
That media speculation will last around a month before they have some kind of cloaked unveiling of some body shapes and specs which will keep the manufacturer name in the press (for FREE) until the late spring unveiling at a car show or other event.
The FREE media will talk for months on that unveiling. The car will then go on sale about 9 months later.
Rinse, wash, repeat. So predictable.
As for the actual car, last I saw written, it's supposed to have an entirely new V12 which will be in a smaller form factor permitting its attachment to an electric storage/deployment device they have been testing. The electrification and a new transmission will permit silent running AND power boost when called upon.
It should be amazing tech. I think in that same write up, there was mention of exhaust being placed prominently and it being illuminated in some new way and possibly light up itself when the car is going in silent electric mode. Cheesy, yes, but when Lamborghini introduces something, it's never regarded as cheesy.
