Chevrolet Corvette Stingray C7 Forum - View Single Post - Manually Controllable Cylinder Deactivation

Does anyone know why there isn't a vehicle, at least that I'm aware of, that allows the driver to control how many active cylinders there are. I realize there are cars with cylinder deactivation, but from what I know, the ECU decides when to deactivate cylinders, based on driving conditions.

After doing some thinking the only thing that stops me from buying an SS as my daily driver is the idea of a high torque RWD vehicle in snowy Maryland winters. If I had the ability to deactivate cylinders (and by extension torque) at will, then I could just drop some snow tires on my car as usual and ride out the winter on 4 or 6 cylinders. Then come spring go back up to 8.

Is there any sort of engineering reason that makes something like this prohibitively expensive or simply not feasible?
