No. An incredible amount of vehicle integration is required to deal with the shifting back and forth. Imagine the balance issues involved with having your V6 engine fire on only three cylinders as opposed to its more natural 6 cylinders. On side of the engine would be firing on two cylinders while the other is firing on one. Continuously.

GM's applications that have Active Fuel Management (AFM) require special engine mounts tuned to adapt real-time to the engine's shift in operating mode. This also requires very sophisticated algorithm management to make certain all the impacted computer modules in the car know when the engine is in full mode or half mode.

Peace,

Martin
