2018 Porsche Panamera 4 E Hybrid | Transparent Transport

2018 Porsche Panamera 4 E Hybrid | Transparent Transport On the road, the Panamera’s powertrain systems are well integrated in the Hybrid Auto mode, with the transition from solely electric power to hybrid operation and back being practically invisible. The car can be cycled through additional modes: E-Power, E-Hold, E-Charge, Sport, and Sport Plus. In E-Power, the Panamera E-Hybrid is capable, Porsche says, of covering up to 31 miles on electricity alone, and it delivers a torquey and mostly serene driving experience, save for some electric-motor whine and an occasional and oddly robust vibration/thrum through the floor. (The source of this thrum remains unconfirmed even after discussions with multiple Porsche engineers, but we suspect some sort of cooling equipment, as it occurred most often after bouts of hard driving and/or acceleration.
