Is the Daihatsu Tanto powerful enough for highway driving?

The Daihatsu Tanto features a 660cc 3-cylinder engine (naturally aspirated or turbocharged), delivering excellent fuel economy often exceeding 20 km/L under typical driving conditions. For buyers considering the Daihatsu Tanto, 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.
