I wonder if they developed a V8 that runs the Atkinson cycle and have the hybrid system support it, what the fuel economy and power figures would be. I know that the Atkinson cycle doesn't make a lot of power, but even if it's around 300ish hp, they could add 150hp of FWD power and still be competitive. That would allow them to avoid the turbo complications, keep the V8 bullet proof, and use their more familiar hybrid tech to bring it up to being competitive with others.
