Verdict
The BYD M6 costs RM109,800, undercutting the Mazda 3 Sedan by RM9,820 while carrying seven people and 580 litres of boot space against five seats and 444 litres. Its 55.4-kWh battery, 420-km claimed range and 89-kW DC charging suit buyers ready to go electric, while rear air-con vents and a 360-degree camera suit family duties. The Mazda is the sharper equipment play for driver assistance: it has seven airbags, blind-spot monitoring, front and rear autonomous braking, adaptive cruise control and lane steering correction. But its 1.5-litre petrol engine returns a rated 5.8 L/100 km, not EV running.
Pick the BYD M6 if you need seven seats, a 580-litre boot and 420 km of electric range for RM9,820 less.
Pick the Mazda 3 Sedan if you want petrol refuelling, adaptive cruise control with Highway & Traffic Jam Assist, and its fuller active-safety kit.
