Verdict
At RM999,888 versus RM749,000, the Mercedes-Benz AMG SL asks RM250,888 more for a four-seat convertible with a 275 km/h top speed. The Porsche Cayenne Coupe Electric is the more rational Malaysian buy if home or destination charging is available: its 113 kWh battery claims 661 km of range, it has five doors and a 584-litre boot against the SL’s 240 litres. The Porsche is also fractionally quicker to 100 km/h at 4.8 seconds, but the SL is 280 mm shorter and 291 mm lower.
Pick the Mercedes-Benz AMG SL if you want the convertible body, 275 km/h top speed and a shorter 4,705 mm grand tourer.
Pick the Porsche Cayenne Coupe Electric if you can charge an EV and need 661 km claimed range, five seats and a 584-litre boot.
