Verdict

For a Malaysian buyer able to charge regularly, the Audi Q8 e-tron is the sharper-value choice: RM143,010 less, yet its dual motors produce 402 hp and 664 Nm, reaching 100 km/h in 5.6 seconds. Its 114-kWh battery claims 582 km of range and accepts 22-kW AC or 170-kW DC charging, while annual road tax is RM545 against the Cayenne’s RM1,632. The Porsche Cayenne counters with a 772-litre boot, 248-km/h top speed, adaptive cruise control and lane-keeping steering correction. Choose it for those practical and driver-assistance gains; choose the Audi for EV running costs and range.
