Fiat dropped the 9-speed automatic gearbox for the Ducato and switched to an 8-speed AT8 transmission to improve performance, comfort, and fuel efficiency, resulting in a 10% reduction in CO2 emissions. The 9-speed gearbox was reportedly prone to issues, including potential torque converter malfunctions and performance problems, especially in heavier applications like motorhomes, which the newer, more efficient 8-speed is designed to address.
Reasons for the switch
- Improved efficiency: The 8-speed automatic transmission (AT8) is designed to be more efficient, which helps lower CO2 emissions by around 10% compared to the previous automatic version.
- Enhanced performance: The new transmission is engineered to provide a more comfortable and refined driving experience with improved shift times and control.
- Addressing 9-speed issues: The 9-speed automatic transmission faced issues, including malfunctions with the torque converter and other performance problems, particularly on models with 160- and 180hp engines and in heavier vehicles like motorhomes. The 8-speed aims to resolve these problems.
- Designed for the application: The 8-speed gearbox is a more suitable and robust design for the needs of the Ducato, including its camper variant
