How far can the Proton eMas 5 travel on a full charge?

Proton eMas 5 has a stated driving range of 400 km. That matters because range is what determines how confidently an EV owner can handle commuting, errands and occasional interstate travel. For most drivers, the headline number should be treated as a planning guide rather than a guaranteed daily result, because traffic, speed and charging habits all affect real-world distance. A useful EV is one that covers normal weekly use without forcing the owner to plan every trip around a charger.
