Steering Modes – Feature Explained

What Are Steering Modes?

Steering modes are electronic settings that modify the steering effort and feedback provided by a car’s power steering system. Instead of a fixed steering feel, these modes allow the driver to select different characteristics, tailoring the steering response to various driving conditions or personal preferences. While some cars have dedicated steering modes, others offer a drive mode selector that also adjusts throttle response, gearbox behavior and, in some cases, suspension stiffness.

How Do Steering Modes Work?

The ability to change steering feel dynamically is facilitated by the electric power steering (EPS) system in your car. Most modern cars come with an electronic power steering system instead of the older  hydraulic power steering setups. Here’s a simplified explanation:

1. Electric Motor Assistance: Unlike hydraulic systems that use a pump driven by the engine, EPS systems use an electric motor to provide steering assistance.
2. Sensors and Control Unit: Sensors detect the driver’s steering wheel input (torque applied) and the vehicle’s speed. This information is sent to the electronic control unit (ECU).
3. Variable Assistance: The ECU then instructs the electric motor to provide a variable amount of assistance.The system provides more assistance at low speed (parking), making the steering lighter and easier to turn with minimal effort. The system can also reduce assistance, making the steering heavier and more precise, which enhances stability and control at high speeds.
4. Mode-Specific Calibration: When you select a different steering mode (Sport, Comfort), the ECU alters the calibration of this assistance. It changes how the electric motor responds to your inputs, effectively altering the “weight” and “feel’ of the steering.

Common Steering Modes Explained

Most cars offering steering modes will typically feature variations of the following:

1. Normal / Standard Mode: It offers a balanced and neutral steering feel, suitable for everyday driving conditions. It’s usually the default setting when you start the car. This mode provides a good compromise between ease of use and feedback, making it versatile for mixed driving environments.
2. Comfort / Light Mode: It makes the steering noticeably lighter and requires less effort to turn the wheel. This mode is ideal for city driving, navigating tight parking spaces, or during long commutes where reduced driver fatigue is desired. It prioritises ease of manoeuverability over direct feedback.
3. Sport / Dynamic Mode: This mode makes the steering heavier and more direct, providing increased feedback from the road. This can make the car feel more “connected” to the road. It is best suited for spirited driving on winding roads or highways where enhanced control and a more engaging driving experience are preferred. The heavier feel provides a greater sense of stability at higher speeds.
4. Individual / Custom Mode (if available): This mode allows the driver to independently adjust various parameters, including steering weight, throttle response, and sometimes suspension stiffness, to create a personalised driving profile. It offers maximum flexibility, enabling drivers to fine-tune the car’s dynamics precisely to their liking.

Benefits Of Different Steering Modes

• Enhanced Driving Experience: Allows drivers to tailor the car’s responsiveness to their preferences and current driving conditions.
• Improved Manoeuverability: Lighter steering in Comfort mode makes parking and low-speed turns effortless.
• Greater Control: Heavier steering in Sport mode provides better feedback and stability at higher speeds, enhancing confidence.
• Reduced Fatigue: Lighter steering can reduce driver effort during long drives or heavy city traffic.
• Versatility: A single car can offer multiple driving personalities, adapting to different moods and scenarios.

Can Steering Modes Be Installed From The Aftermarket?

No, integrated steering modes cannot be installed from the aftermarket. The ability to change steering feel is a fundamental part of the car’s electric power steering (EPS) system and its electronic control unit (ECU). It requires specific hardware and software calibration that is designed and integrated by the manufacturer during the car’s development. Aftermarket modifications to such a critical safety system are generally not possible or recommended.

Affordable Cars in India That Offer Steering Modes?

Steering modes are increasingly becoming a common feature, especially in mid-range to premium segment cars in India. The MG Astor and the now-discontinued Mahindra XUV 300 were some of the first cars in India to offer adjustable steering modes.

Dedicated steering modes are available in the MG Astor and the new Mahindra XUV 3XO. Hyundai and Kia offer drive modes in the Creta and Seltos, respectively, that not only alter engine response but also steering feel and feedback as well. Drive modes can also be found in the VW Virtus and Taigun and their Skoda counterparts, the Slavia and Kushaq.
