Ferrari 458 488 California Steering Wheel Airbag
The steering wheel airbag used on Ferrari 458 Italia, 488 GTB / Spider, and California / California T is an OEM driver-side SRS airbag module integrated into the steering wheel center pad. It is part of Ferrari’s restraint safety system and is designed to deploy in conjunction with seat belts and crash sensors.
OEM Overview
Common OEM part families include:
- 89461500 / 89461502 (driver airbag module variants used across 458, 488, California, FF, F12 platforms)
- Superseded or updated numbers depending on production year and trim specification
These airbags are widely cross-compatible across Ferrari’s V8 and V12 lineup due to shared steering column and restraint system architecture.
Applications
Typically found in:
- Ferrari 458 Italia / Spider / Speciale
- Ferrari 488 GTB / Spider
- Ferrari California / California T
- Some related Ferrari V8/V12 models (platform-dependent)
Function
The steering wheel airbag is part of the Supplemental Restraint System (SRS) and performs the following:
- Rapid inflation during frontal or severe impact events
- Protection of driver’s head and upper torso
- Works in coordination with:
- Seat belt pretensioners
- Crash sensors (front and side impact modules)
- SRS control unit (airbag ECU)
Deployment occurs in milliseconds using a pyrotechnic inflator module.
Construction
Typical OEM Ferrari steering wheel airbag assembly includes:
- Inflator unit (pyrotechnic gas generator)
- Folded airbag cushion (nylon fabric)
- Magnesium or reinforced carrier housing
- Electrical ignition connectors (SRS circuit)
- Integrated mounting into steering wheel center pad
The outer cover is designed to match Ferrari interior trims:
- Black leather
- Tan leather
- Red leather
- Custom stitched variants depending on specification
Engineering Notes
Key design priorities:
- Extremely fast deployment timing
- Controlled inflation force to reduce injury risk
- Integration with steering wheel geometry
- Compatibility with Ferrari SRS ECU logic
- Minimal weight while maintaining structural integrity
Ferrari designs these modules to match specific steering wheel generations, meaning:
- 458, 488, and California share similar architecture
- Variants differ in trim, stitching, and ECU calibration compatibility
Key Features
- OEM Ferrari driver-side airbag module
- Integrated steering wheel center safety system
- Pyrotechnic inflation system
- Platform-shared across multiple Ferrari models
- Designed for high-performance vehicle crash protection
- Trim variants matching interior specifications
