Feature Showdown

Both come with modern infotainment systems.

The BMW M3 stands out with wireless Apple CarPlay/Android Auto, head-up display, panoramic roof, heated front seats, ventilated seats, power tailgate, Harman Kardon audio and ambient lighting that you will not find on the Proton S16. Which feature set matters more depends on your daily routine and priorities.

Drivetrain

The BMW M3 uses a Petrol producing 353kW and 550Nm of torque, sent through a manual to a RWD layout. It covers the 0-100km/h sprint in 4.2 seconds.

The Proton S16 responds with a Petrol making 80kW and 150Nm, paired to a 5 speed manual driving the front wheels.

The BMW M3 has the clear power advantage at 353kW vs 80kW. For most buyers, the way each car feels day-to-day matters more than outright acceleration.

Space & Comfort
