BMW M3 vs Hyundai i45

Specifications in progress

Hyundai i45: we're still completing price, 0-100km/h and transmission.

A blank cell below means we don't have that figure, not that the car scores badly on it. We leave them empty rather than estimate, so any row where one car is blank isn't a like-for-like comparison yet.

Price Breakdown

Pricing for one or both models is yet to be confirmed for the Australian market. We will update this comparison when official RRPs are announced.

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 M3 stands out with wireless Apple CarPlay/Android Auto, head-up display, ventilated seats, power tailgate, Harman Kardon audio and ambient lighting — features our data doesn't list for the Hyundai i45. 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 Hyundai i45 lines up making 148kW and 250Nm, paired to its gearbox driving the front wheels.

The BMW M3 has the clear power advantage at 353kW vs 148kW. For most buyers, the way each car feels day-to-day matters more than outright acceleration.

Space & Comfort

The BMW M3 measures 4,801mm long on a 2,857mm wheelbase, 19mm shorter than the Hyundai i45 at 4,820mm (2,795mm wheelbase). The longer wheelbase on the BMW M3 generally means more rear legroom.

For towing, the BMW M3 leads with a 1,800kg braked capacity vs 800kg. That 1,000kg difference matters if you regularly hitch up.
