as of my knowledge these are full ICE but with start stop feature to reduce idling. In actual there is no second source of power which is in actually in Hybrid cars. by micro Hybrid it means they have this feature which somewhat is a main feature of full Hybrid vehicles which runs on electric motors as well as gasoline engine.
Technically they cant be classified under Hybrid cars. They have just one feature of actual Hybrid cars to save fuel. These cars don't have hybrid battery power pack nor they have an electric drive motors.
