What does rpm on the dashboard mean?

[AngeloAnn]

The rpm on the dashboard stands for the engine's revolutions per minute. Generally, the faster the engine rotates, the more power it can provide. The engine drives piston movement by burning air and gasoline, which in turn rotates the crankshaft to provide power to the vehicle. This force converted to the crankshaft is called torque. The typical limit for a family car's engine is around 6,000 rpm, while high-performance cars can reach between 8,000 to 9,000 rpm. Racing cars can even exceed 10,000 rpm or reach up to 20,000 rpm. The engine's rpm is a crucial data point, and many drivers pay close attention to it while driving. Engines have both a maximum torque rpm and a maximum power rpm, along with an economical rpm range. Most drivers keep their engine within this economical range during regular road driving to ensure better fuel efficiency.
