Verdict
At RM119,620, the Mazda 3 Hatchback costs RM120,268 less than the RM239,888 Mercedes-Benz B-Class, yet returns a rated 5.9 L/100 km against 6.9. The Mercedes counters with a much stronger 163 hp/250 Nm turbo engine, an 8.2-second 0-100 km/h time and a 455-litre boot, useful for a family carrying luggage. For most Malaysian buyers, the Mazda’s lower entry cost, 5-year/100,000 km warranty with free service and richer driver-assist kit make more financial sense. The B-Class is the practical, quicker choice if its price is comfortable.
Pick the Mazda 3 Hatchback if lower purchase and fuel costs, adaptive cruise control, lane steering correction and a five-year free-service package matter more than outright pace and boot space.
Pick the Mercedes-Benz B-Class if you need its 455-litre boot, 163 hp and 250 Nm, powered front seats with memory, and automated parking.
