It's depending on the engine
It's depending on the engine's design to give more torque at lower rpm or having high HP overall with high rpm and good torque. It has nothing to do with the turbocharged V6 vs the V8. In fact, thanks to turbos, the V6 would be able to get more air flow, resulting in much more torque at earlier rpm vs NA engines. The hybrid is there to complement stop and go traffic driving styles. It does make a huge difference for people who spend more time driving city vs highway.
