Suzuki develops advanced auto-shift gearbox
gearshifts, improved efficiency and a more involving driving experience are the
key advantages of a new, advanced gearbox that has been developed by Suzuki.
The new transmission combines the best attributes of manual-shift and automatic
gearboxes by integrating an electro-hydraulic actuator with a five-speed manual
gearbox. The actuator operates the clutch and the gear shifts, and perfectly
synchronises these actions with the engine’s revs to ensure seamless, optimised
The innovative gearbox combines the actuator and controller, and mounts it
directly onto the manual transmission, ensuring integrated, efficient
operation. And since the gearbox remains a manual unit, it doesn’t suffer the
efficiency losses usually associated with torque converter-based automatic
Suzuki engineers say the automated gearbox offers exceptional ease of use, as
it obviates the need for clutch and gearshift operation, while a creep function
when pulling off makes for smooth acceleration from rest.
The gearbox offers both fully automatic and manual shift modes. In the auto
setting, the gearbox selects and shifts gears without the need for driver
intervention, based on prevailing speeds and load conditions.
However, selecting manual mode gives the driver full control over gear shift
selection, just like a conventional manual gearbox, but without the need for a
clutch, thus ensuring an engaging driving experience.
The advanced gearbox has already undergone comprehensive testing and is
expected to be implemented in some of Suzuki’s compact passenger cars,
including the Swift and the Alto, in the future.
