Verdict
At RM999,888, the Mercedes-Benz AMG SL costs RM260,888 more than the RM739,000 Porsche Cayenne Coupe, yet it is 705 kg lighter at 1,810 kg and has 375 hp against 350 hp. The Porsche still reaches 100 km/h in 4.7 seconds, two-tenths ahead, helped by all-wheel drive and its 173-hp electric motor. For Malaysian use, its 90-km EV range, five seats and 698-litre boot make the Cayenne Coupe the more rounded choice. The SL counters with convertible motoring, 275 km/h capability and far lower RM376 annual road tax versus RM2,118.
Pick the Mercedes-Benz AMG SL if a 1,810-kg convertible with 375 hp, a 275 km/h top speed and RM376 annual road tax matters more than rear-seat and boot space.
Pick the Porsche Cayenne Coupe if you need five seats, a 698-litre boot, all-wheel drive and a 90-km EV range for RM260,888 less.
