www.concreteproducts.com November 2017 • 53 INNOVATIONS REPORT TRUCKS "The new interiors speak to the design team's focus on driver com- fort," says Mack Trucks North America Senior Vice President of Sales Jonathan Randall. "Everything from the dash to the racecar-like feel of the steering wheel was carefully designed to make things better for drivers and fleets looking to retain them." "We've incorporated more ergonomics and comfort features to make the driving environment more automotive," adds Highway Prod- uct Manager Stu Russoli. "These make a real difference to the driver who's behind the wheel all day, every day." ANTHEM: BULK-HAUL READY Mack Trucks rolled into Atlanta for the NACV with the new Anthem highway tractor. Available in day cab or long haul configura- tions, its sports efficiency- and productivity-boosting features, weight-conscious options, plus all-new exterior design with opti- mized aerodynamics. "Bulk-haul customers require performance and efficiency to deliver their loads, plus all-day comfort to keep their drivers fresh," notes Russoli. "The Anthem delivers on all of these, while also offer- ing options to further improve productivity. The GHG2017 Mack MP7 engine is rated up to 425 hp and 1,560 lb.-ft. of torque. That's 13-liter power with the fuel efficiency and weight benefits of an 11-liter engine, a perfect combination for bulk-haul applications." The 12-speed Mack mDRIVE automated manual transmission is standard on Anthem models; fully integrated with MP engines, it uses sensors to measure grade, load, speed and other variables to maximize performance and fuel efficiency by automatically select- ing the best gear. The optional 13-speed mDRIVE HD provides an additional creeper gear for improved startability while maintaining highway fuel efficiency. All mDRIVE AMTs are available with Easy Shift. The program revises transmission strategy to reduce load shifting through smoother launches and less aggressive shifting. Load Logic is also available for mDRIVE-equipped, diminishing-load applications to help improve performance and efficiency; it integrates an advanced sensor in the rear suspension with the transmission. The mDRIVE operates as a direct drive transmission whenever a full payload is detected, locking out 12th gear for increased performance and pulling power. When an empty trailer is detected, the transmission switches to overdrive, enabling the 12th gear to lower cruise RPM and maximize fuel efficiency. With weight savings up to 400 lbs. compared to a typical 6x4 configuration, Mack's Anthem-suited 6x2 Liftable Pusher Axle mon- itors trailer weight and adjusts driveline configuration to boost fuel efficiency without impacting performance. Rear suspension sensors determine payload and either lift or lower the foremost rear axle. When an empty load is detected, the axle lifts, allowing the tractor to operate as a 4x2 to net lower drag; potential 3-5 percent fuel efficiency boost; and, up to 20 percent longer tire life. For full loads, the same axle is lowered to provide additional stability and trailer weight distribution.
