At RM183,800, the BYD Sealion 7 costs RM3,441 more than the RM180,359 Mazda 6 Sedan, but brings a 308 hp, 380 Nm motor, AWD and a 6.7-second 0-100 km/h time against the Mazda’s 163 hp, 213 Nm, front-wheel drive and 10.5 seconds. Its 82.5 kWh LFP battery is rated for 567 km and accepts 11 kW AC or 150 kW DC charging. The Mazda counters with a lighter 1,393 kg kerb weight, 5.7 L/100 km rating and a conventional petrol refuelling routine.

Pick the Mazda 6 Sedan if you prefer a 1,393 kg petrol sedan with a 5.7 L/100 km rating, a 62-litre tank and no need to plan charging.
