Is the Mercedes-Benz S-Class powerful enough for highway driving?

The locally assembled (CKD) Mercedes-Benz S-Class in Malaysia is currently primarily offered as the S 580 e Plug-in Hybrid (PHEV) variant. For buyers considering the Mercedes-Benz S-Class, that matters because it affects how easy the car is to live with, whether for commuting, family use, long-distance driving or ownership costs. The useful way to read this is not as an isolated specification, but as a clue to how the car will feel in real daily use.
