Navistar's Heritage of Excellence In Engine Production
Navistar began building engines more than 110 years ago and began experimenting with diesel engines in 1916.

With this experience and Navistar's commitment to offering the industry's latest and best technology, it's easy to understand why MaxxForce engines offer superior performance, reliability and fuel economy.

Industry-Leading Technology In The Modern Era
All MaxxForce engines utilize the following technology, setting them far apart from the competition:
- Compacted Graphite Iron Block (CGI) brings increased durability and power without added weight, compared to typical gray iron. Because CGI has at least 75% higher tensile strength, 45% higher stiffness and near double the fatigue strength of iron, MaxxForce engines offer both lighter weight and superior durability. This platform handles the highest fuel pressures that deliver the best fuel combustion while reducing vibration and noise.
- Advanced Air Managment featuring dual sequential turbochargers - the smaller, primary turbo responds quickly for immediate take-off at low engine speeds - the larger, secondary turbo provides peak power at higher speeds and on steep grades.
- Advanced Fuel System featuring extremely efficient piezo injectors and high injection pressure for precise dosing, injection timing and optimal combustion which results in better fuel efficiency, in-cylinder emissions reduction, and super-quiet operation.
