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.
The BMW 5 Series stands out with wireless Apple CarPlay/Android Auto, head-up display, wireless charging, panoramic roof, heated front seats, power tailgate and Harman Kardon audio that you will not find on the Mazda 6. Which feature set matters more depends on your daily routine and priorities.
Drivetrain
The BMW 5 Series uses a Petrol producing 140kW and 310Nm of torque, sent through a auto to a RWD layout. It covers the 0-100km/h sprint in 5.6 seconds.
The Mazda 6 lines up making 140kW and 252Nm, paired to a 6-speed automatic driving the front wheels.
Power output is identical on paper, so the difference comes down to tuning, weight distribution, and suspension. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Space & Comfort
The BMW 5 Series measures 5,060mm long on a 2,995mm wheelbase, 195mm longer than the Mazda 6 at 4,865mm (2,830mm wheelbase). The longer wheelbase on the BMW 5 Series generally means more rear legroom.
Boot space is 520L in the BMW 5 Series and 474L in the Mazda 6, giving the BMW 5 Series a 46L advantage.
For towing, the BMW 5 Series leads with a 2,000kg braked capacity vs 1,500kg. That 500kg difference matters if you regularly hitch up.
