My 2014 Accord Hybrid engine drives a generator which powers the electric motor. Around 43 mph, if there is not much load, the gasoline engine directly couples to the drivetrain through a clutch. That is all there is. If load is low, and there is an adequate charge, it will drop back to battery even at high speeds. The few occasions where I needed to pass, I believe the engine and the battery drive the electic motor. I was surprised the first time, at how quick the car is.
My previous car was a 2011 Hyundai, with a 6 speed auto. There were times that it would throw a clunky downshift, usually when coming to a stop. When passing, it would un-necessarily drop several gears. I usually reverted to the "manual" shift mode to avoid the noise.
