Verdict
The BMW M5 is the quicker, more overtly performance-led choice, reaching 100 km/h in 3.5 seconds and topping out at 250 km/h against the Porsche Cayenne Coupe Electric’s 4.8 seconds and 230 km/h. But for Malaysian running costs and electric travel, the Porsche is far easier to justify: annual road tax is RM665 versus RM8,408, while its 113 kWh battery claims 661 km against the M5’s 22.1 kWh battery and 67 km EV range. Its 584-litre boot also beats the BMW’s 466 litres.
Pick the BMW M5 if you want the 3.5-second 0-100 km/h time, 250 km/h top speed and a four-door executive sedan layout.
Pick the Porsche Cayenne Coupe Electric if you want 661 km of claimed EV range, 390 kW DC charging and far lower annual road tax.
