What does the S and I mean on a Subaru steering wheel?

The "S" and "I" markings on a Subaru steering wheel refer to the vehicle's driving modes. The "S" stands for "Sport" mode, which enhances the vehicle's performance and responsiveness, while the "I" stands for "Intelligent" mode, which prioritizes fuel efficiency and smooth driving characteristics.


Understanding the Subaru Driving Modes


Subaru vehicles often come equipped with multiple driving modes, allowing drivers to tailor the car's performance to their preferences or driving conditions. The "S" and "I" markings on the steering wheel are part of this feature, providing a quick and intuitive way for drivers to select the desired mode.


Sport (S) Mode



  • Enhances the vehicle's acceleration and responsiveness by adjusting the engine, transmission, and steering settings.

  • Provides a more engaging and dynamic driving experience, suitable for spirited driving or when extra power is needed, such as during passing maneuvers or merging onto highways.

  • May result in slightly higher fuel consumption compared to the Intelligent (I) mode.


When the "S" mode is selected, the driver can expect a more immediate throttle response, tighter steering, and a more aggressive transmission shift pattern, all of which contribute to a sportier driving feel.


Intelligent (I) Mode



  • Prioritizes fuel efficiency and smooth, comfortable driving characteristics.

  • Adjusts the engine, transmission, and other systems to optimize for better fuel economy and a more relaxed driving experience.

  • Suitable for everyday driving, commuting, or situations where fuel efficiency is a higher priority than performance.


In the Intelligent (I) mode, the vehicle's systems are tuned to provide a more gradual throttle response, smoother transmission shifts, and a generally more relaxed driving feel, all while aiming to maximize fuel efficiency.


The choice between Sport (S) and Intelligent (I) modes ultimately depends on the driver's preferences and the driving conditions at hand. Drivers can easily switch between the two modes using the dedicated buttons or switches on the steering wheel or center console, allowing them to adapt the vehicle's performance to their needs.
