Verdict
At RM406,800, the locally assembled BMW X4 costs RM23,088 less than the Japanese-built Lexus RZ, yet gives you a 525-litre boot, 21-inch wheels and a panoramic sunroof. Its 249 hp, 350 Nm 2.0-litre turbo petrol drivetrain reaches 100 km/h in 6.3 seconds, but returns a rated 8.5 L/100 km and carries RM439 annual road tax. The RZ is the faster, lower-road-tax choice: its twin motors make 308 hp and 435 Nm for 5.3 seconds to 100 km/h, with a 71.4 kWh battery rated for 440 km.
X4
Pick the BMW X4 if you want the lower RM406,800 entry price, a 65-litre petrol tank, 240 km/h top speed and a panoramic sunroof.
RZ
Pick the Lexus RZ if you want 308 hp and 435 Nm from twin electric motors, a 440 km EV range, 150 kW DC charging and five years of manufacturer warranty.
