If you want to understand more how the PHEV works and the various actual power modes/outputs, I think you need to read through the Technical Highlights Manual.

The answer is not a simple addition of what could be possible max output.
The website is wrong to quote 200bhp as it does as ic engine output. The engine is indeed an Atkinson Cycle, modified from the 'normal' 2ltr Mitsubishi petrol engine, with steadily rising torque and low peak power revs, which I take will give the best efficiency to drive the generator.
The Brouchers have a better list of the various outputs under Technical Specifications.
