The New Mack MP13 Engine: Built to Deliver More.

We didn’t just update the Mack® MP®13 engine. We rebuilt it from the inside out. The new EPA 2027-compliant Mack MP13 is the most powerful and efficient 13-liter engine Mack has ever produced, delivering up to 540 horsepower, 1,950 lb.-ft. of torque and up to 3% improved fuel efficiency compared with the previous MP13 engine. With peak torque starting as low as 900 RPM, stronger stopping power, advanced engine enhancements and an aftertreatment system designed to meet EPA 2027 emissions standards without adding a maintenance step, the MP13 continues to deliver the power, efficiency and reliability Mack customers depend on. The Mack MP13 will be available across Mack highway and vocational models, including the Mack Pioneer™, all-new Mack Anthem®, all-new Mack Granite® and all-new Mack Keystone®.
