Called Duonic, the transmission combines automated driving with the advantages of a manual transmission. As with a fully automatic transmission it is a two-pedal system, there is an accelerator pedal, a brake pedal and a selector lever. The selector lever allows automatic or manual gearshift mode to be selected.
The M038S6 Duonic transmission has six forward and one reverse gears as well as a park function.
Duonic features non-wearing wet clutches, which lower maintenance costs by eliminating the need to replace worn discs. A creep function has been added, as is usual for automatic transmission with a torque converter. This enables the vehicle’s speed to be easily controlled when moving slowly – for example when manoeuvring or in stop/start traffic – and hill-starts are also easier.
Mitsubishi Fuso Truck and Bus Corporation (MFTBC) based in Kawasaki, Japan, last year sold around 99,500 light, medium and heavy trucks and buses. It is owned 85% by Daimler with the remaining 15% held by Mitsubishi subsidiaries.
