- Hydraulic Power Steering (HPS): Used in older models, utilizing hydraulic fluid pressurized by an engine-driven pump
- Electro-Hydraulic Power Steering: A transitional technology using an electric pump to pressurize hydraulic fluid
- Manual Steering: Very early models featured steering systems with no power assistance
Each system offers different characteristics in terms of steering feel, maintenance requirements, fuel efficiency, and compatibility with driver assistance features. Modern VW Polos predominantly use EPS technology for its efficiency and programmability advantages.
The VW Polo's steering system operation varies by type, but most modern models utilize Electric Power Steering (EPS) which works as follows:
- When the driver turns the steering wheel, a torque sensor in the steering column detects the direction and force applied
- The EPS control module processes this input along with vehicle speed data from the ABS system
- Based on these inputs, the control module determines the appropriate level of assistance needed
- An electric motor connected to the steering column or rack provides precisely calculated assistance
- The mechanical components (rack and pinion) convert the rotational movement into lateral movement of the tie rods
- The tie rods push or pull on the steering arms connected to the wheel hubs, turning the wheels
This system provides variable assistance (more at low speeds, less at high speeds) while consuming power only when steering assistance is needed, improving fuel efficiency compared to hydraulic systems that run continuously.
Maintenance requirements vary by steering system type:
For Electric Power Steering (EPS) systems:
- Regular inspection of steering components for wear or damage
- Checking for proper electrical connections and function
