Verdict
For just RM4,430 less, the BMW X5 is the more useful Malaysian purchase: it carries five, has a 650-litre boot and uses all-wheel drive, while matching the BMW Z4’s 5.4-second 0-100 km/h time and 250 km/h top speed. Its 308 hp, 540 Nm inline-six also beats the Z4’s 255 hp and 400 Nm. The Z4 counters with a 749 kg lower kerb weight, rear-wheel drive and convertible body, but its two seats and 280-litre boot make it a focused second car. Factor in the X5’s RM1,637 annual road tax against RM379 for the Z4.
Pick the BMW X5 if you need five seats, a 650-litre boot and all-wheel drive without giving up the Z4’s 5.4-second sprint.
Pick the BMW Z4 if a two-seat rear-wheel-drive convertible and far lower RM379 annual road tax matter more than passenger and luggage space.
