The PACCAR engine brings a new level of innovation through industry-leading quality, exceptional efficiency and proven performance. PACCAR has now delivered over 1 million engines globally, and for over 50 years has provided innovative engine solutions and an unwavering commitment to superior customer service and support.

Reliability & Durability

Transport professionals will find the PACCAR MX-13 engine credentials and specifications ideal for a variety of heavy-duty applications including single trailers, B-double and tipper, and dog.


The PACCAR MX-13 uses Compacted Graphite Iron (CGI) in both the cylinder block and head. CGI is lighter and stronger than traditional grey iron and offers operators an excellent horsepower-to-weight ratio to optimize payload. The distinctive PACCAR MX-13 crankshaft reduces weight and increases power for quicker acceleration and smoother overall operation.



To comply with the Euro 5 requirements for exhaust gas emissions, PACCAR MX-13 engines use SCR technology, optimized for high performance with low fuel consumption and low emission of particulate matter.

An optimized combustion process results in low emissions of particulate matter allowing for long service intervals, which reduces the total oil waste over the truck’s service life.



PACCAR MX-13 engines deliver excellent torque at low engine speeds and high performance over a wide rev range. The PACCAR MX-13 engine brake offers optimum stopping power on long gradients.

A rear mounted gear train reduces torsional vibrations that occur with front engine gear trains. The design places gears within the flywheel circumference, where the primary energy transfer takes place, resulting in greater harmonic balancing, which reduces wear and tear and provides drivers with a quieter operating environment.




SMART fuel injection technology is used to deliver high injection pressures combined with precise injection timing and multi-point injection. The outcome is an optimum combustion process and excellent fuel efficiency.

The PACCAR MX-13 features low operational engine speeds with excellent torque characteristics, thereby requiring fewer gear changes, which results in lower fuel consumption.




When it comes to riding the road, safety isn’t just one more thing to think about – it’s everything. It’s why we design and build every Kenworth cab using aircraft quality alloys for structural strength. It’s why our trucks give you outstanding visibility – forward, back and all around. It’s why we application engineer and manufacture here in Australia to suit local conditions and operations, put your controls within easy reach and balance all the components of your Kenworth with precision.
