Here are some changes that occur when the "S" button is pressed:
1. Engine and Transmission:
- The throttle response becomes more sensitive, allowing for quicker acceleration.
- The transmission shifts at higher RPMs, keeping the engine in its power band for improved performance.
2. Steering:
- The steering may feel heavier and more responsive, providing better control during spirited driving.
3. Suspension:
- The suspension might become stiffer to reduce body roll and improve handling.
4. Exhaust Note:
- The exhaust note might become louder or more pronounced to enhance the driving experience.
By activating the "S" button, the Volvo S40 transitions into a more dynamic and performance-oriented mode, allowing the driver to enjoy a sportier and engaging driving experience. However, it's important to note that the "S" mode may also affect fuel economy and ride quality, so it's best to use it judiciously based on the driving conditions.
