International® A26 Truck Engine
BUILT FOR UPTIME AND BACKED BY A BEST-IN-CLASS WARRANTY.

The new International® A26 is engineered with proven components that deliver optimal uptime and fuel efficiency in a
lightweight design. This big bore engine has been relentlessly tested with hundreds of thousands of hours of dyno testing
and millions of real-world test miles.

The A26 produces up to 475 HP and 1750 lb.-ft. of torque, yet is 600-700 lbs. lighter than traditional big-bore engines. It
features North America’s first Class 7-8 Compacted Graphite Iron (CGI) crankcase design for greater strength, plus an all new
cylinder head and other refinements for up to a 5% fuel economy improvement over the engine it replaces. Engine
braking power is increased by up to 67% for confident braking performance, particularly at low- to mid-RPMs
and at higher altitudes.

Cummins B6.7
Engineered for reliability, durability and fuel efficiency, the Cummins B6.7 doesn’t have an off day. With an impressive range of horsepower for a variety of medium-duty applications, every aspect of the B6.7 has been improved to deliver the lowest cost of ownership with maximum uptime. Add in industry leading service from International® Trucks and Cummins, plus a two-year, unlimited mileage engine warranty, and you’re sure to have an engine that’s always ready to work when you are.

Excellent Power
The B6.7 features High Pressure Common Rail (HPCR) fuel injection for constant pressure and strong performance at every rpm. Multiple injection events per cycle make this engine quiet and smooth to operate. Ratings range from 200-325 hp (149-242 kW).

Fuel Economy
The B6.7 gets the highest fuel economy of any engine in its class. The addition of an air intake throttle makes the exhaust gas recirculation (EGR) system more efficient, reducing parasitic losses to increase fuel economy and lower operating costs.

Trusted Reliability
Base engine warranty coverage for the B6.7 includes parts and labor on warrantable failures for the base engine and the aftertreatment system. Cummins base warranty coverage is good for two years/unlimited mileage. Extended coverage plans are available for the base engine and aftertreatment system.

Cummins L9
A great track record of established performance continues to improve with the Cummins L9. With the highest power density of any engine in its class, the L9 delivers the right amount of might to even the heaviest medium-duty applications.

Proven Performance
The L9 shares common technology with the Heavy-Duty ISX15 and ISX12 to deliver exceptional performance. Common components include the XPI fuel system, a high-capacity electronic control module (ECM) and the patented Cummins VGT™ Turbocharger from Cummins Turbo Technologies. Ratings range from 260-380 hp (194-283 kW), with 550 lb.-ft. of clutch engagement torque. Optional features include engine braking for better control, rear-engine power take off (REPTO) and front-engine power take off (FEPTO).

Exceptional Value
The refined L9 delivers up to 2 percent better fuel economy than the previous model with the inclusion of an air intake throttle and a modified VGT™ Turbocharger for greater EGR and overall efficiency. Even better is the fact that maintenance intervals and related costs remain virtually unchanged. Combined, all of these features give L9 owners a lower total cost of operation.

Greater Dependability
Heavy-duty roller followers, bypass oil filtration and targeted piston cooling all contribute to longer service life – even in the toughest work environments. Plus other considerations, such as replaceable wet liners, make the L9 easier to maintain and rebuild. All of which adds up to longer engine life and a higher resale value.

Cummins L9 Specifications
• Advertised Horsepower – 260-380 hp
• Peak Torque – 720-1250 lb.-ft.
• Governed Speed – 2100/2200 rpm
• Clutch Engagement Torque – 575 lb.-ft.
• Number of Cylinders – 6
• System Weight – 1,912 lb.

• Aftertreatment System* – 217 lb.

Cummins X15
Proven Muscle for the long haul.

Legendary Cummins reliability is available in new X15 Performance Series and X15 Efficiency Series configurations. The X15 Efficiency Series produces up to 500 HP with advanced fuel- saving technology that includes dynamic electronic controls with ADEPT features, enhanced engine breathing and an optimized combustion process that leverages Cummins’ proprietary VGT™ Turbo and XPI fuel system. The X15 Performance Series generates up to 565 HP by upgrading virtually every critical component for enhanced air handling, faster throttle response and even stronger braking power at lower RPM.

VGT Turbo
Industry-leading proprietary design is four to six times stronger than previous designs for improved durability. The new design also includes a new impeller for rapid boost and improved braking.

Excellent Power
The Cummins ISX15 combines the brute power needed to haul loads up steep inclines with fuel economy that your bottom line will appreciate. With a broad range of horsepower ratings up to 600hp and 2,050 lb.-ft. of torque, the ISX15 has the power to get any job done right. The variable geometry turbocharger enhances response and control with electric actuation for infinite adjustment, providing exact boost at any rpm.

Single High-Capacity ECM
Efficient, single ECM management of the engine and after-treatment system for exceptional performance and fuel efficiency.

Cummins After-treatment System
A new flow-through design provides better heat management for improved efficiency and increased ash capacity for fewer cleanings. This integrated system is up to 40% lighter and 60% smaller than some two-part systems.
