Is 4 cylinder equals 3000 Cm3 in a car?

Not exactly having 4 cylinders doesn’t automatically mean the engine is 3000 cm³. Engine size depends on the volume of each cylinder, so a 4-cylinder engine could be anywhere from around 1000 cm³ up to over 2500 cm³ depending on the car. For example, when cars come in for routine checks at Metrowest Car Service, the mechanics often point out that two cars with the same cylinder count can have very different engine sizes and performance. Are you asking this because you’re looking at a specific car, or just curious about how engine sizes work?
