Car engine sizes are expressed as the volume of their cylinders. Thus a 2 Liter car would have an engine with a cylinder volume of 2 liters. This would be more powerful than a 1.5 liter car. However there is a complication, if the car has a turbo charger then more power can be obtained from a smaller engine than its basic liter size because the booster compresses the fuel and air before it gets to the cylinders.
