Ford Mustang: we're still completing seat count, 0-100km/h, ground clearance, braked towing and fuel tank.

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

The BMW 4 Series starts from $83,500 before on-road costs, while the Ford Mustang opens at $72,990. That makes the Ford Mustang the more affordable entry point by $10,510.

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 $91,850 and $80,289 respectively.

Over 5 years, the running costs favour the BMW 4 Series by roughly $4,275 in fuel alone.

Safety Rundown

We hold no ANCAP data for the BMW 4 Series. ANCAP's published record does not give the Ford Mustang a rating. With no pair of ratings to compare, the active-safety features in the spec table above are the fairer comparison.

Feature Showdown

The BMW 4 Series features a 14.9-inch touchscreen paired with a 12.3-inch digital dash, 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 heated front seats, ventilated seats, Bang & Olufsen audio and ambient lighting. 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 Ford Mustang offers leather accented.

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 7.5 seconds.

The Ford Mustang responds with a Petrol making 232kW and 445Nm, paired to a 10-speed automatic with paddle shifters 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.
