Verdict
Just RM912 separates these two, so the choice is not about purchase price. The BMW i4 M50 brings 537 hp, 795 Nm and a 3.9-second 0-100 km/h time, against the Lexus RZ’s 308 hp, 435 Nm and 5.3 seconds. It also travels 70 km farther at 510 km and DC-charges at 200 kW. The RZ counters with a 522-litre boot, 165 mm more height, a five-year vehicle warranty and RM730 less annual road tax. For a Malaysian buyer who values pace and longer intercity legs, the BMW has the clearer edge; the Lexus makes more sense as the roomier SUV alternative.
i4 M50
Pick the BMW i4 M50 if 537 hp, a 3.9-second 0-100 km/h sprint, 510 km range and 200 kW DC charging matter more than SUV height and boot space.
RZ
Pick the Lexus RZ if you want the taller 1,635-mm SUV body, 522-litre boot, five-year warranty and RM335 annual road tax.
