Verdict
The RM19,000 gap buys the iX’s 402 hp, 700 Nm dual-motor drivetrain and 100.6-kWh battery, rated for 602 km, along with 22-kW AC and 175-kW DC charging. It reaches 100 km/h in 5.1 seconds, 1.2 seconds ahead of the X4. For a Malaysian buyer able to charge, that is the more persuasive daily and outstation package. But the X4 is 635 kg lighter, has a 525-litre boot and reaches 240 km/h; its 2.0-litre petrol engine is rated at 8.5 L/100 km.
Pick the BMW iX if you can charge regularly and want 602 km of EV range, 700 Nm and the quicker 5.1-second sprint.
Pick the BMW X4 if you prefer petrol power, a 525-litre boot and a 635 kg lighter SUV with a 240 km/h top speed.

iX vs X4 FAQ
Is the BMW iX or BMW X4 better?
With regular charging access, the iX is better for 402 hp, 700 Nm, 602 km EV range and 5.1-second acceleration. Choose the X4 if you want a larger boot and petrol power.
What is the price difference?
The BMW iX costs RM19,000 more than the BMW X4.
Which has more luggage space?
The BMW X4 has the larger boot at 525 litres, beating the BMW iX’s 500 litres by 25 litres.
How long does charging take?
The iX's 100.6 kWh battery takes about 4.6 hours for a full AC charge, and an estimated 40 minutes from 10% to 80% on a DC fast charger at its 175 kW peak.
Which one is locally assembled?
The X4 is assembled in Malaysia (CKD), while the iX is fully imported (CBU) from Germany. Local assembly generally helps pricing and spare-parts supply, and CKD programmes usually signal a longer-term commitment to the model here.
