Mercedes-Benz S-Class vs Porsche Cayenne Coupe

Verdict

At RM738,888 for the Mercedes-Benz S-Class and RM739,000 for the Porsche Cayenne Coupe, the money is basically level; the split is about use case. The S-Class is the rear-seat car, with a 3,216 mm wheelbase, powered reclining rear seats, massage and a 100 km EV range. The Cayenne Coupe hits back with 0-100 km/h in 4.7 seconds, all-wheel drive and a huge 698-litre boot. One is for being driven. The other is for driving and carrying more.

S-Class

Pick the Mercedes-Benz S-Class if rear-seat comfort, 100 km EV range and CCS 60 kW DC charging matter more than boot space and all-wheel-drive pace.

Cayenne Coupe

Pick the Porsche Cayenne Coupe if you want the quicker car, all-wheel drive and 698 litres of luggage space at almost the same price.
