Verdict
At RM171,800, the BYD Seal costs RM15,609 more than the Mazda 6 Sedan, but brings 308 hp, 360 Nm and a 5.9-second 0-100 km/h time against 153 hp, 200 Nm and 10.5 seconds. Its 82.56-kWh battery has a quoted 570-km range and 150-kW DC charging, while the Mazda uses 5.7 L/100 km from a 2.0-litre petrol engine. The Mazda counters with a 489-litre boot, 89 litres more than the Seal, and lower annual road tax by RM44. For tech and active safety, the Seal is decisively better equipped.
The 6 Sedan 2.5 20th Anniversary Edition 2023 (RM240,848) sits above every Seal variant here, so the verdict compares the closest-priced pairing — use the selectors above to match any two trims.
Pick the BYD Seal if you can charge an EV and want 570 km of quoted range, 150-kW DC charging, 308 hp and a fuller active-safety suite.
Pick the Mazda 6 Sedan if a 489-litre boot, lower RM379 annual road tax and petrol refuelling suit your routine better than EV charging.
