Verdict
At RM846,800, the BMW M3 costs RM107,912 more than the RM738,888 Mercedes-Benz S-Class, yet it is the harder-driving choice: 503 hp, 650 Nm, all-wheel drive and 3.5 seconds to 100 km/h. The S-Class answers with a 28.6-kWh battery, 100-km EV range and a rated 1 L/100 km, useful for buyers able to charge regularly. It is also 359 mm longer, with a 359-mm longer wheelbase, and its rear seat equipment is in another league. Pick pace and a 480-litre boot in the M3; pick chauffeur-grade rear comfort in the Mercedes.
M3
Pick the BMW M3 if 503 hp, 3.5-second 0-100 km/h pace, all-wheel drive and a 480-litre boot matter more than rear-seat luxury.
S-Class
Pick the Mercedes-Benz S-Class if you want 100 km of EV range, a 3,216-mm wheelbase and heated, ventilated and massaging rear seats.
