Santana's appropriate RPM is around 2500. If the RPM is too low, the fuel will not burn sufficiently in the cylinders, leading to carbon buildup in the engine, which can cause damage over time. Higher RPM results in greater wear on the engine. The Santana measures 4475mm in length, 1706mm in width, and 1469mm in height, with a wheelbase of 2603mm and a top speed of 185 km/h. It is equipped with a 5-speed manual transmission, has a trunk capacity of 466L, a fuel tank capacity of 52.8L, and the engine delivers a maximum power of 82 kW with a maximum torque of 145 Nm.

For a car like the Santana, keeping the engine speed within a reasonable range is crucial for performance and longevity. I often service this type of vehicle, and the normal idle speed should be between 600 to 800 RPM, stabilizing after the car starts. While driving, it's best to shift gears around 2000 to 2500 RPM, ensuring smooth engine operation and fuel efficiency. When accelerating or driving on highways, it's fine for the RPM to reach 3000, but avoid prolonged periods above 3500 RPM to prevent excessive wear and increased fuel consumption. If the RPM fluctuates erratically, it might indicate a dirty air filter or spark plug issues, requiring prompt inspection. Regular engine maintenance to keep the RPM normal can extend the car's lifespan by several years.

I've been driving my Santana for several years and found that the ideal idle speed is around 700 RPM. For daily city driving, maintaining around 2000 RPM feels most comfortable, providing sufficient power without causing vibration noise. On highways, you can increase to 2500-3000 RPM for better acceleration and slightly improved fuel efficiency. In frequent traffic jams, keeping the RPM near 1500 with gentle throttle input works fine. Note that cold starts in winter may temporarily show higher RPM, but it quickly returns to normal. Avoid consistently keeping RPM below 1000 or exceeding 4000, as this may cause shaking and engine damage. Simply follow the tachometer and keep it in the middle range.

Over a decade of driving a Santana has taught me that an idle speed of 750 RPM is ideal, and maintaining around 2000 RPM while driving is best. Higher RPMs waste fuel, lower ones lack power. Don't overthink the details—just listen for smooth engine sounds.

I drove my friend's Santana and felt it was smooth at an idle speed of 700 rpm. When accelerating during normal driving, it responded quickly at around 2500 rpm, and it was fuel-efficient at 2000 rpm on long trips. If the rpm is unstable, check the fuel system or sensors. Remember, proper control is good for the car.
