Mack Trucks has announced the addition of two new features for its truck models. These include the availability of Mack Predictive Cruise Control with Econo-Roll as a standard feature on Mack Anthem and Mack Pinnacle Models. In addition, the Mack mDRIVE Automated Manual Transmission (AMT) now features a left and right dual Power Takeoff (PTO) option for highway and vocational customers.
Mack Predictive Cruise Control with Econo-Roll
Mack Predictive Cruise combines the Mack mDRIVE AMT with GPS, monitoring driver speed, engine load and road topography, memorizing those conditions when cruise control is set. The next time the driver travels the same route, Mack Predictive Cruise will communicate to the transmission to ensure the optimal gear for fuel efficiency is chosen.
“Predictive Cruise is truly an engineering feat as it uses the knowledge gained from past routes to automatically adjust speed and torque when the route is again driven,” said Stu Russoli, Mack highway product manager. “The system can store up to 4,500 routes, offers maximum fuel efficiency and improves total cost of ownership for customers.”
Mack Predictive Cruise can increase fuel efficiency by up to 1% and does not require a constant GPS connection. After a short connection to GPS, Mack Predictive Cruise recognizes the hill, sends the communication to mDRIVE, which automatically knows the optimal speed and gear strategy for the upcoming terrain.
Mack Predictive Cruise constantly monitors speed, engine load, weight and the road gradient in order to select the best gear for the road ahead. When approaching a hill, Predictive Cruise allows slightly more speed. The mDRIVE AMT then maintains the highest gear possible, remaining in that gear and preventing downshifts if unnecessary to crest the hill. Econo-Roll, which temporarily disengages the driveline before the downhill descent, allows the truck to roll, reducing fuel consumption.
When traveling downhill, Mack Predictive Cruise maintains vehicle speed, utilizing kinetic energy and softly applying the engine brake. Because the hill is stored in the vehicle’s memory, Predictive Cruise recognizes it and knows when the gradient will even out, allowing the truck to maintain its speed for the next incline.
mDRIVE Automated Manual Transmission with dual PTO option
Available for customers with Mack Granite, Mack Anthem and Mack Pinnacle models with 12-speed, 13-speed and 14-speed Mack proprietary mDRIVE AMTs, the premium option offers cleaner routing to frame- and body-mounted equipment.
“The left and right dual PTO allows drivers to run their hydraulic pump equipment on both sides of the vehicle, improving the ease of use on jobsites and maximizing flexibility for applications requiring the operation of multiple PTOs,” said Tim Wrinkle, Mack construction product manager. “This also increases functionality for customers.”
Ideal for both dry and wet bulk applications, the dual PTO is available with clutched adapters with DIN-mounted or SAE flange connections. Both the left and right dual PTO ports rotate counterclockwise, and the adapters are interchangeable and easily adjusted in the field.
The dash switches work independently of each other through an air solenoid, so both PTOs do not have to be on for one to work. The dual PTO is also available with up to two direct-mount hydraulic pumps factory-installed, as well as retrofit options.
The proprietary Mack mDRIVE that powers the dual PTO delivers increased fuel efficiency, smoother shifts and a more comfortable driving experience. When paired with proprietary Mack MP engines and axles, the integrated powertrain offers an improved total cost of ownership for customers.
