Mack Trucks has introduced drivetrain systems that executives said improves load-hauling efficiency and fuel economy of their Pinnacle tractor for bulk haulers: Load Logic, which controls the top two gears of its mDrive automated transmission, and a self-operating 6×2 liftable pusher axle setup. For applications that routinely haul out heavy and return empty, Mack Load Logic and the 6×2 with liftable pusher axle are designed to monitor trailer weight and adjust the truck’s driveline configuration to boost fuel efficiency without degrading performance.
