Citroën C1 High-Performance Final Drive Ratio 4.411 Citroën C1
Citroën C1 High-Performance Final Drive Ratio 4.411 Citroën C1
Upgrade the acceleration and drivetrain response of your Citroën C1 1.0 12V with this High-Performance 4.411 Final Drive, designed for compatible vehicles equipped with the 20TT manual gearbox.
This used and tested final drive gear set replaces the standard 3.550 ratio with a shorter 4.411 final drive, helping improve acceleration, torque delivery and responsiveness for motorsport and performance applications.
Product Overview
This Citroën C1 4.411 Final Drive is designed as a performance upgrade for compatible 20TT manual gearboxes.
By changing the standard final drive ratio from 3.550 to 4.411, the overall gearing becomes shorter, allowing the engine to move through the gears more quickly and improving acceleration.
This makes the setup particularly suitable for motorsport, sprint, hill climb, circuit and other performance-focused applications where rapid acceleration and drivetrain response are important.

- Manufacturer: Citroën
- Model: C1
- Engine: 1.0 12V
- Model Years: 2004–2015
- Gearbox: 20TT manual gearbox
- Final Drive Ratio: 4.411
Compatibility must be confirmed before ordering. Verify that your Citroën C1 is equipped with the correct 20TT manual gearbox.
If you are unsure about compatibility, contact Art of Speed with your vehicle and gearbox details before purchasing.
Technical Specifications
- Performance Final Drive Ratio: 4.411
- Standard Final Drive Ratio: 3.550
- Gearbox: 20TT manual gearbox
- Engine Application: 1.0 12V
- Condition: Used and tested
- Application: Motorsport and performance driving
The shorter 4.411 ratio increases overall torque multiplication at the driven wheels compared with the standard 3.550 final drive.
As a result, acceleration is improved, although engine RPM at a given road speed will also increase and theoretical maximum speed may be reduced.
Performance Benefits
- Shorter 4.411 final drive ratio
- Improved acceleration through the gears
- Stronger torque delivery at the wheels
- Improved response from lower speeds
- More responsive drivetrain behaviour
- Suitable for competition and performance-focused Citroën C1 builds
The shorter gearing is particularly beneficial in competition environments involving frequent acceleration, technical sections and repeated speed changes.
Motorsport Application
This 4.411 final drive is intended for motorsport and performance-focused Citroën C1 applications.
According to the supplied product specification, this ratio has been approved for use in the City Division of the Stock Cup racing series promoted by ANPAC.
Motorsport regulations may change over time. Competitors should always verify the current championship technical regulations before purchasing or installing the component.
