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.
