What is Power Steering: Everything You Need to Know!

Have you ever marveled at how effortlessly you can turn the steering wheel of your car, even when navigating tight corners or parking in cramped spaces? That's the wonder of power steering! In this comprehensive guide, we'll take a closer look at power steering—what it is, how it works, its various types, the benefits it offers, essential maintenance tips, and the importance of maintaining a detailed service history to keep your steering system running smoothly.

Understanding Power Steering

Power steering is a system designed to assist drivers in steering their vehicles by reducing the amount of physical effort required to turn the steering wheel. In traditional manual steering systems, the driver has to exert considerable force, especially at low speeds or when the vehicle is stationary, to maneuver the wheels. However, with power steering, this effort is significantly reduced, making driving more comfortable and less strenuous. Also When buying or selling a car, the presence of power steering can affect its value

Types of Power Steering Systems

  1. Hydraulic Power Steering (HPS): Hydraulic power steering is the traditional system found in many older vehicles and some modern ones. It operates using hydraulic pressure generated by a pump, which is typically driven by the engine. The hydraulic fluid, stored in a reservoir, is pressurized by the pump and directed to the steering gear or rack, where it assists in turning the wheels.
  2. Electric Power Steering (EPS): Electric power steering represents a more modern approach to power assistance. Instead of relying on hydraulic fluid and pumps, EPS systems utilize an electric motor to provide steering assistance. Sensors detect the driver's steering input and vehicle speed, adjusting the level of assistance accordingly. EPS offers benefits such as improved fuel efficiency, precise control, and integration with advanced driver assistance systems.

How Power Steering Works

1. Steering Input: The driver initiates a steering input by turning the steering wheel in the desired direction.

2. Sensor Detection (For Electric Power Steering - EPS): In electric power steering (EPS) systems, sensors detect the direction and magnitude of the driver's steering input, as well as the vehicle's speed.

3. Control Unit Processing (For EPS): The sensor data is processed by the electronic control unit (ECU), which calculates the appropriate amount of assistance needed based on factors such as vehicle speed, steering angle, and driving conditions.

4. Assistance Generation: In hydraulic power steering (HPS) systems, a hydraulic pump, typically driven by the engine, pressurizes hydraulic fluid.
In electric power steering (EPS) systems, an electric motor generates the necessary assistance to aid in steering.

5. Power Assistance Application: The pressurized hydraulic fluid (HPS) or electric motor (EPS) applies force to the steering mechanism, assisting the driver in turning the wheels.

6. Wheel Movement: The applied force from the power assistance mechanism helps to move the steering linkage or rack and pinion, causing the vehicle's wheels to turn in the desired direction.

7. Feedback and Adjustment: Throughout the steering maneuver, the system continuously monitors the driver's input and vehicle dynamics.
In EPS systems, the assistance level may be adjusted dynamically based on changing driving conditions, ensuring optimal steering feel and responsiveness.

8. Steering Return: Once the steering input is completed, the driver returns the steering wheel to its neutral position.
The power assistance mechanism disengages, allowing the steering system to return to its resting state.

9. System Rest: The power steering system remains inactive until the next steering input is initiated by the driver.

10. Repeat: The process repeats with each steering maneuver, providing consistent and reliable assistance to the driver as needed.

Benefits of Power Steering

  • Ease of Steering: The primary advantage of power steering is its ability to reduce steering effort, especially at low speeds or when parking. This makes driving more comfortable and less fatiguing, particularly for drivers with limited physical strength.
  • Enhanced Safety: Power steering enhances vehicle control and maneuverability, allowing drivers to respond quickly to changes in road conditions or unexpected obstacles. With lighter steering, drivers can maintain better control in emergency situations, reducing the risk of accidents. This improved control can also lead to fewer instances of traffic violations, such as e-challans, as drivers can navigate their vehicles more effectively. Additionally, maintaining a valid car insurance policy is essential for protecting against financial losses in the event of accidents or other unforeseen incidents on the road.
  • Improved Fuel Efficiency: Electric power steering systems, in particular, contribute to fuel efficiency by operating only when assistance is needed. Unlike hydraulic systems, which constantly draw power from the engine, EPS consumes less energy, resulting in fuel savings over time.

Best Cars in India with Power Steering

In India, several car manufacturers offer models equipped with power steering as a standard feature. Some of the best cars in India known for their advanced power steering systems include:

  1. Maruti Suzuki Swift: Renowned for its sporty design and agile handling, the Maruti Suzuki Swift comes equipped with responsive power steering, making it a favourite among urban commuters and driving enthusiasts alike.
  2. Hyundai i20: The Hyundai i20 boasts a stylish exterior, premium interior, and advanced features, including electric power steering for effortless maneuverability in city traffic and on long drives.
  3. Honda City: As one of the most popular sedans in India, the Honda City offers a refined driving experience, with smooth and precise power steering that enhances comfort and control on every journey.

Maintenance Tips for Power Steering Systems

Proper maintenance is essential to ensure the longevity and reliability of your vehicle's power steering system. Here are some key maintenance tips to keep in mind:

  1. Regular Fluid Checks: Check the power steering fluid level regularly and top it up if necessary. Low fluid levels can cause the system to operate inefficiently or even fail altogether.
  2. Fluid Flushing: Consider flushing the power steering system and replacing the fluid according to the manufacturer's recommendations. Over time, contaminants and debris can accumulate in the fluid, compromising system performance.
  3. Inspect for Leaks: Periodically inspect the power steering system for any signs of leaks, such as fluid puddles beneath the vehicle or damp spots on hoses and connections. Addressing leaks promptly can prevent fluid loss and potential damage to system components.
  4. Professional Inspections: Schedule regular inspections with a qualified mechanic to assess the overall condition of the power steering system. A professional inspection can help identify any issues early on and prevent costly repairs down the line.


Power steering is a technological marvel that has transformed the driving experience for millions of motorists worldwide. Whether you're navigating busy urban streets or embarking on a long-distance road trip, the benefits of power steering are undeniable—enhanced comfort, safety, and control behind the wheel. By understanding how power steering works and following proper maintenance practices, you can ensure that your vehicle's steering system remains in top condition for years to come. So, the next time you effortlessly glide around a tight corner or smoothly parallel park, remember to thank the wonders of power steering for making it all possible!
