Mack Powertrain & Suspensions
We’re America’s first integrated truck and engine manufacturer. That means all Mack powertrain components are designed to work together for optimum performance, increased fuel efficiency and lower maintenance costs.
Mack Engines & Transmissions
Mack® MP® engines are proven, fuel-efficient and clean-running, with a range of 325 to 605 HP, and torque ratings topping out at a whopping 2,060 lb.-ft. With muscle and low-end torque, these engines conquer the workday, mile after mile.
Mack® transmissions offer a number of industry exclusives, including a triple-countershaft design, flexible PTO options and shiftable multi-speed reverse capability. As an integrated manufacturer, we offer the industry’s best-built transmission & the sound engineering for it to work with the rest of your truck.
The MP7® engine is ideal for weight-sensitive applications. This 11-liter engine boasts an amazing power-to-weight ratio and maximizes payloads with the help of a horsepower range from 325 to 405 HP and torque ratings from 1,200 to 1,560 lb.-ft.
The MP8® engine provides the muscle-to-shoulder heavy-duty vocational workloads and highway applications. This 13-liter engine has a horsepower range from 415 to 505 HP and torque ratings from 1,460 to 1,860 lb.-ft.
The Mack MP8-TC takes the reliability of the MP8 engine and adds the intelligence and efficiency of turbocompounding to capture lost energy, convert it into power and reduce fuel consumption.
SCR and Clean Diesel
The MP10® is the most powerful engine we’ve ever built. This 16-liter engine has a horsepower range from 515 to 605 HP and torque ratings from 1,860 to 2,060 lb.-ft. It’s perfect for heavy equipment, special-permit and severe heavy-haul applications.
Natural Gas (ISX12 G)
Mack has embraced the energy revolution by expanding the availability of natural gas engines. For years we’ve produced an energy-efficient Mack® TerraPro™ model running on natural gas, and now we’re expanding the same technology to our vocational and regional-haul applications.
With the Mack® mDRIVE™ transmission built exclusively for Pinnacle tractors, you can now get a complete Mack Pedigree™ Powertrain in an automated manual transmission. This 12-speed, two-pedal transmission maximizes driver comfort, payload and fuel economy. The mDRIVE includes an impressive base torque input capacity of 1,920 lb.-ft. and is offered with Direct Drive or Overdrive.
It’s built tough, but doesn’t hold you down—weighing 237 pounds less than the other guy. And this transmission integrates seamlessly with your truck’s powertrain to improve efficiency, increase uptime and lower cost. With mDRIVE HD truck and driver perform better and last longer—so it takes less to do more.
