Over 5 years, the running costs favour the BMW 4 Series by roughly $2,565 in fuel alone.

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

The BMW 4 Series features a 10.3-inch touchscreen, while the Ford Mustang gets a 13.2-inch display and 12.4-inch instruments. Apple CarPlay and Android Auto are standard across both.

The Ford Mustang counters with wireless charging, heated front seats, ventilated seats, Bang & Olufsen audio and ambient lighting that the BMW 4 Series does not offer. Which feature set matters more depends on your daily routine and priorities.

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 Ford Mustang responds with a Petrol I4 Turbo making 232kW and 475Nm, paired to a 10-speed automatic driving the rear wheels.

The Ford Mustang has the clear power advantage at 232kW vs 135kW. For most buyers, the way each car feels day-to-day matters more than outright acceleration.

Space & Comfort

The BMW 4 Series measures 4,770mm long on a 2,851mm wheelbase, 41mm shorter than the Ford Mustang at 4,811mm (2,719mm wheelbase). The longer wheelbase on the BMW 4 Series generally means more rear legroom.
