I'm gonna go on a limb and say that reliability excludes powetrain?! Otherwise this report is next to useless / inconclusive if one is questioning the overall reliability of mentioned models, specifically those that consist of 2-3 or more different types of powetrains/engines.
F10 has 3 different engines that most of us here can easily attest to doubting or questioning them as being ranked highest reliability in it's class.
