One thing that always puzzled me was how the gas engines in hybrids were so efficient. Technology Connections has a great video explainer: <a href="https://www.youtube.com/watch?v=KnUFH5GX_fI" rel="nofollow">https://www.youtube.com/watch?v=KnUFH5GX_fI
tl;dw: constant RPM and a weird stroke geometry where the power stroke is longer than the other strokes to extract more energy from the expanding gasses.
Yes, but it doesn't mean the overall system is better because of losses during the power conversion. It's usually better to have the engine driving the wheels directly which is possible with a continuously-variable transmission (CVT).

And yes the Atkinson cycle helps
