Could be this the Ferrari 812 Superfast TURBO/KERS? - Silent 812 test mule in action at Fiorano

I was able to film this Ferrari 812 Superfast prototype does some low speed tests at Fiorano racetrack. The peculiarity of this car protected by a camouflage was just the almost nonexistent noise. The speed of the car was low, but not too much to keep the exhaust valves closed .. maybe it was a Ferrari 812 Superfast T (Turbo) or an 812 with a hybrid system? Guys, write in the comments what you think about this car. Thanks for watching.
