Verdict
At RM100,000, the BYD Atto 2 costs RM9,800 less and is the clearer choice for drivers able to charge regularly: its 51.1-kWh battery delivers 345 km of EV range and accepts 82 kW DC charging. The Proton eMas 7 PHEV fights back with a much larger 528-litre boot, 2,755-mm wheelbase and rear air-con, plus a petrol plug-in-hybrid powertrain for journeys beyond its 83-km EV range. The BYD is also marginally quicker to 100 km/h, at 7.9 seconds versus 8.0 seconds.
Pick the BYD Atto 2 if you want 345 km of electric range, faster 82 kW DC charging and a lower entry price.
Pick the Proton eMas 7 PHEV if you need the 528-litre boot, larger C-segment cabin and petrol backup beyond its 83-km EV range.
