The Isuzu 3.0L turbo-diesel engine delivers a massive 140kW of power and 450Nm of torque, matched with either a 6-speed manual or 6-speed automatic transmission. Using highly-advanced Isuzu common-rail diesel technology, this balances the power with superior fuel efficiency. The end result is outstanding performance to tackle any hill, overtake on the freeway and tow what you like without constant visits to the fuel station.

At the heart of D-MAX is the Isuzu turbo-diesel engine range. With over a century of specialist engineering experience, the D-MAX is more than ready to handle whatever you throw at it.

3.0L Turbo-Diesel

The highly refined Isuzu 4JJ3-TCX 3.0L turbo-diesel common rail engine which offers superior fuel efficiency thanks to low friction, fuel injection optimisation and a large front-mounted intercooler.

The advanced 3.0L turbo-diesel generates 140kW of power and a peak torque output of 450Nm from a low 1,600 to 2,600rpm. The high levels of torque from a low rpm provide strong take-off and acceleration and aid drivability with consistent torque output through the majority of the rev-range.

1.9L Turbo-Diesel

Available for select models in both 4x4 and 4x2 drivetrain options, the Isuzu RZ4E-TC 1.9L turbo-diesel engine generates 110kW of power and 350Nm of torque whilst achieving supreme fuel efficiency and refined operation.

With 2.8T+ (manual) and 3.0T+ (auto) braked towing capacity, it offers a flexible and economical option that’s ideal for fleet, tradies and small business operators.

6-Speed Transmission

The ‘Rev-Tronic’ 6-speed automatic gearbox with sequential sports mode automatically selects the most appropriate shift and lock-up points according to the driver’s behaviour, vehicle load and road speed.

The 6-speed manual transmissions benefit from a new dual mass flywheel, which absorbs vibrations and torque pulses from the engine for smoother and more efficient driveability and transmission longevity.

The advanced 3.0 litre turbo-diesel engine produces 140kW and an avalanche of torque on demand, with 450Nm available from just 1,600 through to 2,600rpm. This provides exceptional take-off and acceleration with a broad, flat torque band aiding overall drive-ability - also perfect for when carrying a load, or towing up to 3.5T+.

Dirty, dusty off-road adventure is where the D-MAX really shines, with engineering and technology features that'll keep you going across all types of terrain.


People rely on you, and you can rely on your D-MAX. The Isuzu turbo-diesel engine is full of engineering details that only a truck manufacturer would think of, with each one of these making this ute truck tough.


Fancy replacing your timing belt? Probably not – so the D-MAX doesn’t have one. Instead it uses a heavy duty steel timing chain to last the life of the engine. The double scissors design in the 3.0L engine also offers increased durability and reduced noise.

Diesel engines are 20-30% more efficient than regular petrol engines. The D-MAX is so fuel efficient because our engineers have decades of experience in commercial transport, where every litre counts.
+3.5-tonne braked towing capacity on all 3-litre engine D-MAX models, 3.0-tonne braked towing capacity on 1.9-litre engine automatic transmission models, 2.8-tonne braked towing capacity on 1.9-litre engine manual transmission models when fitted with an optional genuine Isuzu UTE tow bar kit or tow tongue kit and an Electronic Brake Controller. Up to 800mm of wading depth on all D-MAX models when travelling at a consistent speed of 7km/h. Water ingress may occur if speed is not maintained or if the vehicle is static in water above 350mm.
