All the cars that are available on the market do not start at the same RPM. The RPM usually depends upon the type of engine and the power it produces. If your engine size is about 2.0 liters, the RPM it should be starting on is anywhere between 500 to 800 RPMs. if the size of the engine is bigger than that, the RPMs should sit anywhere between  550 to 750 rotations per minute. If your RPM starts anywhere between 600 to 1000, you have nothing to worry about and it means that your engine is working properly. Depending on the conditions your car is surrounded by, your car can also have different RPMs when it starts. For example, during cold weather, your car’s RPM usually starts at a higher than normal RPM. This rate drops as your car warms up to the optimal engine temperature.
