BMW M3

M3 Competition M xDrive Pro Pack

Verdict

The RM846,800 BMW M3 costs RM107,912 more than the RM738,888 Mercedes-Benz S-Class, and that money primarily buys pace: 503 hp, 650 Nm, all-wheel drive and a 3.5-second 0-100 km/h time against 362 hp, 500 Nm, rear-wheel drive and 5.2 seconds. The S-Class is the better chauffeured or electric-commute sedan, with a 28.6-kWh battery, 100 km EV range and a 3,216-mm wheelbase. Its rear-seat kit is in another class, but its 350-litre boot trails the M3’s 480 litres.

M3

Pick the BMW M3 if 503 hp, 650 Nm, all-wheel drive and a 3.5-second 0-100 km/h sprint matter more than rear-seat luxury and plug-in capability.

S-Class

Pick the Mercedes-Benz S-Class if you want 100 km of EV range, a vastly richer rear cabin and a 4-year manufacturer warranty.
