The new International A26 is engineered with proven components to deliver optimal uptime and fuel efficiency in a lightweight design.
Built from the proven MAN D26 engine crankcase, the A26 produces up to 475 horsepower and 1,750 lb-ft of torque from a design that is 600 too 700 pounds lighter than a traditional 15-liter big bore engine. Its components have been carefully engineered to deliver uncompromising uptime as well as class-leading fuel efficiency, reduced weight and quiet operation.
Engineered to deliver up to an average of 5% greater fuel economy, the A26 has a simplified air management system, featuring a new variable geometry turbocharger. Fuel injection pressure is maximized by the engine's 2,500 bar (36,300 psi) high pressure common rail fuel system. Coupled with new cylinder head coolant passaages that are 50% less restrictive to reduce parasitic loss to the water pump, the A26 reduces both fuel consumption and emissions.
The A26's uniquely sculpted crankcase, which is isolated with the oil pan through a specially designed rubber gasket, absorbs vibration and reduces harshness for a quieter in-cab experience. The engine's six-blade fan, specially designed gear teeth, and sophisticated calibration and programming are specifically built to reduce engine noise.
The A26 is backed with the industry's best engine warranty: two years, unlimited miles. The warranty reflects confidence in the engine's reliability and durability, which have been confirmed through extensive validation and testing process, including:
- Millions of real-world test miles over the harest North American roads, including high altitudes and temperatures as low as -40 degrees F.
- Full validation cycles (concept design, statistical and product validation) over a period of years to identify, correct and retest any issue.
