The mDRIVE is an automated manual transmission (AMT) developed by Mack Trucks for heavy-duty vehicles. This system combines the operational simplicity of an automatic transmission with the fuel efficiency and performance advantages often associated with manual transmissions. It utilizes a computer-controlled clutch and gearshift mechanism, eliminating the need for a traditional clutch pedal and allowing the driver to select gears electronically or automatically. A typical application would be a long-haul trucking operation seeking optimized fuel consumption and reduced driver fatigue.
This technology offers several potential advantages, including improved fuel economy through optimized shift points, reduced driveline wear due to smoother shifting, and enhanced driver comfort, particularly in demanding driving conditions. It effectively bridges the gap between traditional manual and fully automatic transmissions, offering a balance of efficiency and ease of use. Its development reflects the ongoing trend in the trucking industry toward automated systems that aim to improve operational efficiency, vehicle performance, and driver satisfaction. Historically, this type of transmission has played a significant role in improving heavy vehicle operation.
