Verdict
At RM738,888, the Mercedes-Benz S-Class costs RM39,888 more than the RM699,000 Porsche Cayenne Electric, yet they serve sharply different Malaysian routines. The Mercedes gives rear-seat occupants power adjustment, ventilation, massage and an ottoman, while its 2,999 cc plug-in hybrid has a 100-km EV range and a 67-litre fuel tank. The Porsche counters with 642 km of EV range, 390-kW DC charging and a 781-litre boot against 350 litres. It is also quicker to 100 km/h, though the S-Class retains a 250-km/h top speed versus 230 km/h.
Pick the Mercedes-Benz S-Class if rear-seat comfort, its 3,216-mm wheelbase and petrol-backed plug-in hybrid running suit your use.
Pick the Porsche Cayenne Electric if you want 642 km of EV range, 390-kW DC charging and a much larger 781-litre boot.
