Only the early-model Toyota Prius used Atkinson cycle engines, up until 2003 or so. You'd be hard pressed to find a modern hybrid using Atkinson cycle. Any modern Prius uses conventional engines with variable valve timing.

Most still seem to refer to these engines as Atkinson cycle even Toyota themselves: "The Prius retains its 1.8-liter VVT-i equipped Atkinson cycle petrol engine (2ZR-FXE)" https://global.toyota/en/detail/9827044 https://global.toyota/en/detail/9827044 https://en.wikipedia.org/wiki/Toyota_ZR_engine#2ZR-FXE https://en.wikipedia.org/wiki/Toyota_ZR_engine#2ZR-FXE
