Probably could make a bit more power, but since the car is a series hybrid and the engine only turns a generator, they've likely optimized the port timing, injector size, etc for 'single point' operation at its most efficient operating point. Maybe one of the rotary performance shops will find a way to splice a pair of E-shafts & make a center housing. ;-)

It's pretty hard to make a hybrid a/c make sense, unless you're going to something like distributed power/props, to get VSTOL/STOL performance. The extra weight of the generator and the efficiency losses going through two energy conversions hurts. Since an a/c spends most of its time in a relatively narrow range of power settings, the engine should get optimized for single point operation similar to the series hybrid generator engine. We don't have the constant power changes that make parallel hybrid setups work well for cars.

When I was reading the article, I was wondering if the entire power package could be pulled out of a junk yard in the near future, and then used to create a hybrid a/c?  Looks like they’re limiting rpm to only 4700 (?), so a bit more power might be possible if spinning it faster?

Just stumbled on this article which says the rotary has returned!
