Mack Pedigree Powertrain

Gear Guide — Spring Truck Show Roundup

Mack’s new “Pedigree Powertrain” is an integrated powertrain with engine, transmission and axles. Pedigree-spec’d trucks will be adorned with a gold Bulldog hood ornament. “Components designed to work together simply work better,” said John Walsh, vice president of marketing.

Mack is extending that integration throughout the entire truck ownership experience with a powertrain package called Super Econodyne, an integration that includes the company’s C125 overdrive rear axles, MP8-445SE engines and mDrive transmissions. The system is designed to down-speed the engine speed by about 200 rpm at highway speeds. At 65 mph, the engine will cruise at 1,160 rpm.
