Fuel-cut is maintained, and the retarded intake cam timing reduces the amount of air sucked in around the throttle flap and through the engine to almost zero. This is a very low-resistance state for the engine to be in, and it only takes a kilowatt or two to keep all that merrily turning. Since the regenerative drag is reduced or eliminated, the car will coast along a lot farther -- still losing speed on the flat, but fairly slowly, and one can easily maintain speed or accelerate going downhill. It's really the higher-speed equivalent of "glide" with perhaps a little more brought in from the battery to compensate for the spinning dead weight of the engine. If held long enough, the HV battery charge will begin dropping just like it would during gentle EV running at lower speed."

I guess I will try feathering the throttle and see if I can induce “Warp Stealth mode" at a spead greater than 39mph.
