Mack® mDRIVE™ HD 13-Speed Now Standard on Mack Granite® Models
Mack has announced that in 2017, the 13 speed automated manual transmission (AMT) will be standard offering on the Granite model trucks.
“Making the mDRIVE HD 13-speed standard on the Granite is a natural evolution of our industry leadership,” said Dennis Slagle, president of Mack Trucks. “Since its introduction, the mDRIVE has become incredibly popular – starting first with highway and more recently with many heavy-duty vocational applications. The introduction of the 13- and 14-speed gears expands the range and performance in vocational applications so much so that it is only natural for it to become our standard offering in the Granite model.”
Available in direct or overdrive configurations, the new Mack mDRIVE HD 13-speed offers a low reduction creeper gear ratio designed for easier startability on steep grades or when the truck is carrying a heavy load. This improved startability also allows customers to select a faster rear axle ratio. The faster ratio decreases engine rpm at highway speeds, saving fuel as the truck travels between job sites.
Thanks to the new low reduction creeper gears, the mDRIVE HD 13- and 14-speed transmissions not only improve performance in off-road, heavy haul and construction applications, but also for on-highway applications. As a result, Mack now offers both new mDRIVE HD variants in Mack Pinnacle™ models.
