330-390 hp
1,250-1,450 lb.-ft. of torque
To succeed in a competitive business, you need an engine and an organization behind it that are always performing and working for you. Navistar's MaxxForce® Big Bore engines have revolutionized how the world looks at Class 8 commercial diesels. Designed specifically for International® brand heavy vehicles, with a combination of technologically advanced materials and components, these engines deliver outstanding fuel economy, excellent power characteristics, an exceptionally smooth and quiet ride, and high strength without added weight.
- EPA compliant with MaxxForce Advanced EGR, the only no-hassle emissions solution for 2010 standards
- A Compacted Graphite Iron cylinder block is 40% stiffer with 75% higher tensile strength, and 200% greater fatigue resistance than iron used in other Class 8 diesel engines
- Low vibration levels prolong the life of the engine by protecting it from ordinary wear and tear
- Fuel system combined with twin series turbo chargers, delivers peak torque at a lower RPM, which allows for earlier upshifts when accelerating and fewer downshifts when climbing hills
- Internal testing has shown a 2.4% fuel efficiency advantage over the leading I5L engine
- Over 500lbs lighter than the nearest I5L engine with similar power output
- Peak torque is achieved at 1000 RPM (just over idle) and sustains at higher RPMs for a more responsive off-the-line driving experience
