Price Breakdown

The BMW M2 starts from $109,900 before on-road costs, while the BMW 4 Series opens at $83,500. That makes the BMW 4 Series the more affordable entry point by $26,400.

Once you factor in stamp duty, registration, CTP insurance, and dealer delivery, expect to add roughly 8-12% on top of the RRP depending on your state. That puts estimated driveaway prices in the ballpark of $120,890 and $91,850 respectively.

Over 5 years, the running costs favour the BMW 4 Series by roughly $3,280 in fuel alone.

Safety Rundown

Both the BMW M2 and BMW 4 Series hold a 5-star ANCAP safety rating. Adult occupant protection scored 94% for the BMW M2 and 96% for the BMW 4 Series.

Where the two diverge is in active safety technology. The BMW M2 packs more ADAS features with 6 out of 10 key systems fitted, compared to 4 in the BMW 4 Series.

Both include the essentials: autonomous emergency braking, lane keep assist, adaptive cruise control, a reversing camera.

Feature Showdown

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

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

Drivetrain

The BMW M2 uses a Petrol producing 338kW and 550Nm of torque, sent through a 8-speed auto to a RWD layout. It covers the 0-100km/h sprint in 4.1 seconds.

The BMW 4 Series responds with a Petrol making 135kW and 300Nm, paired to a auto driving the rear wheels. It gets to 100km/h in 5.8 seconds.

The BMW M2 has the clear power advantage at 338kW vs 135kW. In the real-world sprint, the BMW M2 is 1.7s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.

Space & Comfort
