Verdict
At RM468,888, the Lexus RX costs RM140,112 less than the RM609,000 Porsche Cayenne, while its annual road tax is RM754 against RM1,632. The Cayenne earns its premium with 348 hp, 500 Nm and a 5.7-second 0-100 km/h time, beating the RX’s 275 hp, 430 Nm and 7.6 seconds. It also carries 772 litres in the boot. But the RX counters with a 14-inch screen, ventilated rear seats, rear climate control and a five-year unlimited-mileage warranty—useful advantages for Malaysian family use.
Pick the Lexus RX if rear-seat comfort, richer everyday equipment, lower running tax and a five-year unlimited-mileage warranty matter more than outright pace.
Pick the Porsche Cayenne if you want 348 hp, a 5.7-second century sprint, 772 litres of boot space and adaptive air suspension.

RX vs Cayenne FAQ
Is the Lexus RX or Porsche Cayenne better?
The Cayenne is better for acceleration, output and cargo capacity: 348 hp, 500 Nm, 5.7 seconds to 100 km/h and a 772-litre boot. The RX is better equipped for rear passengers and has lower road tax plus longer unlimited-mileage warranty cover.
What is the price difference?
The Porsche Cayenne costs RM140,112 more than the Lexus RX. Its annual road tax is also RM878 higher, at RM1,632 versus RM754.
Which has the better rear-seat accommodation?
The Lexus RX is the stronger rear-passenger choice. It has heated and ventilated rear seats, power recline and folding, plus single-zone rear automatic climate control. The Cayenne has 40:20:40 split-folding rear seats with remote release and powered rear side-window sunshades.
Which one is locally assembled?
The Cayenne is assembled in Malaysia (CKD), while the RX is fully imported (CBU) from Japan. Local assembly generally helps pricing and spare-parts supply, and CKD programmes usually signal a longer-term commitment to the model here.
