m DRIVE™
The Mack m DRIVE™ transmission is an automated manual transmission originally built for Mack. This 12-speed, two-pedal transmission not only delivers smooth shifts every time, but also maximizes driver comfort, payload and fuel economy.
AUTOMATED CONTROL
Easier, safer, smarter hauling
With the m DRIVE™ automated manual transmission, there’s no clutch pedal, and shifting is operated by intelligent software and engine integration. It continuously monitors changes in grade, vehicle speed, acceleration, torque demand, combined vehicle weight and air resistance to optimize fuel economy on every drive.
MaxBrake
m DRIVE™ has got your back
Pushing MaxBrake on the single DIN keypad optimises PowerLeash engine braking performance by downshifting if necessary, maintaining ideal engine speeds between 1700rpm and 2100rpm when in braking mode.
Grade gripper
Winning the uphill battle
Grade Gripper eliminates rollback by keeping your position steady on an incline for up to three seconds after the brake pedal is released.
MackCellerator™
Power when you need it
Increase engine RPM while automatically downshifting the transmission and accelerating to enable a safe and quick passing maneuver. This keeps the driver’s hands on the wheel and eyes on the road.
Easy to operate
The m DRIVE™ transmission makes it simple and comfortable to drive a truck, opening up staffing to a larger pool of drivers. m DRIVE™ is automated, and that means less wear and tear on drivers. So they can finish the job strong and stay focused.
Minimal service
m DRIVE™ automated manual transmission is based on proven technology and superior design that requires minimal service and significantly reduces maintenance costs.
Reduced wear and tear
m DRIVE™ features constant monitoring and intelligent shift strategies so there’s less stress on the driveline, resulting in a longer life for your transmission and more money toward your bottom line.
