Verdict
The Proton eMas 7 is the more complete family SUV: its 215 hp motor cuts the 0-100 km/h time to 6.9 seconds, and its 461-litre boot is 81 litres bigger. It also brings rear air-con vents, blind-spot monitoring and an 11 kW AC charger. The BYD Atto 2 counters with the same 345 km range, a marginally larger 51.1 kWh battery and 82 kW DC charging. For Malaysian buyers who mainly want a compact city EV, the smaller BYD is the leaner choice; the Proton gives more car for a modest outlay increase.
Pick the BYD Atto 2 if you want the lower entry price, a 4,310 mm body and power adjustment for both front seats without giving up 345 km of range.
Pick the Proton eMas 7 if you need the quicker 6.9-second sprint, 461-litre boot, larger C-segment cabin footprint and extra safety equipment.
