Proton eMas 5 has dimension information listed as 700 mm. Dimensions matter because they decide how easy the car is to park, how stable it feels on the highway and how much space passengers may enjoy inside. For family buyers, a larger footprint can mean better cabin comfort, but it also needs to remain manageable in malls, tight housing areas and older parking bays. The best way to read this figure is as a practicality signal, not just a measurement.
