Yes, it is. Some cars naturally have a higher operating temperature, but the gap is relatively small. This is due to the engine's thermostat and its rated temperature.  Depending on each model, thermostats can function at various temperatures. This is the temperature at which the thermostat "opens" for flow and heat exchange. As the thermostat's temperature rating rises, so does the engine's operating temperature. Knowing your car's typical operating temperature will help you spot potential problems.
