Mack Trucks released its latest integrated powertrain option, the Mack MP7 405 Super Econodyne with improved fuel efficiency.

The MP7 SE is available with 405 horsepower and 1,560 pounds-feet of torque and comes packaged with Mack’s mDrive automated manual transmission, proprietary drive axles and custom software.

“Customers who spec the fuel-efficient MP7 SE package with the overdrive AMT and Mack’s C125/126 axles can experience up to a four percent fuel efficiency improvement compared with the standard MP7 and AMT package," said Roy Horton, Mack director of product marketing.

The MP7 is lightweight and comes with a power-to-weight ratio ideal for maximizing payloads, according to Mack. The powertrain is 2014 Greenhouse Gas certified and is made for regional and bulk haul applications up to 80,000 pounds on flat terrain and up to 70,000 pounds on rolling hills.
