Hybrids give the engine a hard time and are as requiring of maintenance as any ICE car is. Perhaps even more, long term. It appeals to people who want to have the best of both worlds The actual range on the Battery is very short and the vehicles are expensive. Out of warrantee I wouldn't want to OWN one.. I HAVE driven them and find them unpleasant and the fuel saving varies a lot depending whether its Hilly or higher constant speed on the flat.
