Safety Rundown

ANCAP safety ratings have not been published for both models yet. We will update this section when crash test results are available.

Feature Showdown

Both come with modern infotainment systems. Apple CarPlay and Android Auto are standard across both.

The BMW M2 counters with head-up display, heated front seats and Harman Kardon audio that the BMW 4 Series does not offer. Which feature set matters more depends on your daily routine and priorities.

Interior trim differs: the BMW 4 Series gets sensatec synthetic leather upholstery while the BMW M2 offers merino leather.

Drivetrain

The BMW 4 Series uses a Petrol producing 135kW and 300Nm of torque, sent through a auto to a RWD layout. It covers the 0-100km/h sprint in 5.8 seconds.

The BMW M2 responds with a Petrol making 390kW and 650Nm, paired to a 8-speed auto driving the rear wheels. It gets to 100km/h in 3.8 seconds.

The BMW M2 has the clear power advantage at 390kW vs 135kW. In the real-world sprint, the BMW M2 is 2.0s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.

Space & Comfort
