Verdict
The BMW X6 costs RM735,800, undercutting the Mercedes-Benz GLS at RM999,888 by RM264,088, yet it is the quicker car: 0-100 km/h takes 5.4 seconds against 6.1 seconds despite the GLS producing 362 hp and 500 Nm to the BMW’s 335 hp and 450 Nm. The Mercedes is the proper seven-seater, with a 3,135 mm wheelbase and air suspension, but it is 247 mm longer and 153 mm wider. For five occupants and a larger 580-litre boot, the X6 is the sharper buy.
X6
Pick the BMW X6 if you want to save RM264,088, carry five people with 580 litres of boot space and reach 100 km/h 0.7 seconds sooner.
GLS
Pick the Mercedes-Benz GLS if you need seven seats, adaptive air suspension and adaptive cruise control with stop-and-go capability.
