Engineering Perspective

This actuator is part of the Huracán’s advanced steering rack system, which replaces purely hydraulic steering with an electro-mechanical setup for faster response and tighter integration with vehicle dynamics systems.

It is responsible for:

• Translating steering input into rack movement with high precision
• Supporting variable steering assistance based on speed and drive mode
• Integrating with Lamborghini’s LDVI (vehicle dynamics control) systems
• Maintaining steering stability under high lateral loads

The result is the signature Huracán steering feel: direct, immediate, and highly communicative at high performance driving speeds.
