Mack MP7 Diesel

325–425 HP, High-Power/Low-Weight Champion

Power: 325 – 425 HP | Torque: 1,260 – 1,560 lb-ft

The Mack MP7 delivers one of the best power-to-weight ratios in the industry—perfect for bulk haulers, refuse fleets, and any weight-sensitive route where payload and turnaround times drive profits. Advanced MP-series technology slashes emissions and keeps your trucks running cleaner, while the compact inline-6 design sheds hundreds of pounds compared with larger blocks.

Why Choose the MP7?

• Payload Advantage — lighter engine weight means more revenue-earning cargo per trip.
• Broad Torque Plateau — up to 1,560 lb-ft for confident launches and fewer shifts.
• Cleaner Operation — next-gen after-treatment meets strict emissions standards without compromising fuel economy.
• Mack-Built Durability — forged internals and robust cooling for long service intervals and low life-cycle costs.
