Not only is Mazda pursuing a rotary engine to power a vehicle, Davis admits Mazda is also investigating ways to use the design in tandem with an electric motor, with the pistonless engine responsible for charging an extended-range EV's batteries. Given the compact size and relatively low torque supplied by a rotary, this application would seem to hold promise. Of course, we've heard some of this before.
And what of a SkyActiv V6? Davis makes it clear there's no room in the SkyActiv stable for a six-cylinder, saying that the company will focus on lighter platforms and forced-induction four-cylinder engines instead.
