GREENSBORO, N.C. – Mack Trucks is offering customers with concrete mixer applications a lighter-weight solution with its Granite model, equipped with the 2017 Mack MP7 11-liter engine and the Mack mDRIVE HD 14-speed automated manual transmission with creeper gears.

“The Mack Granite model has always handled the most challenging jobs, which is why it was the No. 1-selling Class 8 heavy duty conventional straight truck in the U.S. in 2015 based on Polk data,” said Tim Wrinkle, Mack construction product manager. “Now with our 2017 powertrain, the Granite is helping increase our customers’ return on their investment through improved efficiency, performance and reliability.”

Mack says the MP7 is 51 pounds lighter with up to 425 horsepower and 1,560 lb.-ft. of torque. Fuel efficiency on the new engine is also up by 2.1%.

“The Mack MP7 offers the power and performance to manage any task, but in a smaller displacement engine to provide weight savings,” Wrinkle said. “The integration with the Mack mDRIVE HD 14-speed allows for seamless communication among components so that the vehicle is always in the right gear without the driver having to manually shift, reducing driver fatigue and increasing safety. It also provides a deep ratio of 32:1 in the lowest creep gear to facilitate low speed functionality such a curb pouring when needed.”

The mDRIVE HD with creeper gears is approximately 150 pounds lighter than an automatic transmission.
