Verdict

At RM495,071, the Mercedes-Benz E-Class Coupe costs RM253,929 less and carries RM376 annual road tax, against RM665 for the Porsche Cayenne Coupe Electric. The Porsche answers with far stronger acceleration: its dual motors produce 436 hp and 835 Nm for 0-100 km/h in 4.8 seconds, versus 254 hp, 370 Nm and 6.4 seconds from the Mercedes. For a Malaysian buyer needing five seats and a 584-litre boot, the Porsche is plainly more useful, but the Mercedes’ 250 km/h top speed beats its 230 km/h figure.

E-Class Coupe

Pick the Mercedes-Benz E-Class Coupe if you want to spend RM253,929 less, pay lower annual road tax and prefer a 250 km/h petrol coupe.

Cayenne Coupe Electric

Pick the Porsche Cayenne Coupe Electric if you need five seats, a 584-litre boot, all-wheel drive and 4.8-second 0-100 km/h performance.
