Generally speaking, higher RPMs mean that a vehicle is going faster. This is because the engine works harder, and the wheels turn more each minute. However, other factors can affect speed, such as the gear ratio, tire size, and power output. So, while higher RPMs are often an indicator of speed, it's not the only factor to consider. There you have it, now you don’t have to wonder what RPM is in a car and whether it means a faster vehicle.
