Engine capacity

Engine capacity refers to the volume swept by all the pistons of an engine, within their bores, from the top to the bottom of their travel. Measured in litres, cubic centimetres (cc) here in Australia. Engines with greater capacities are usually more powerful and provide greater torque at lower rpms but also consume more fuel. However there are exceptions, for example a Subaru Impreza WRX with a 2.0 L engine capacity has more power than a Ford Falcon with a 4.0L engine capacity. This is due to the turbocharger found in the Subaru.
