Does a Larger Displacement Mean Faster Speed?

[LeAnderson]

Generally speaking, a larger displacement does result in faster speed, but this understanding is oversimplified and not entirely accurate. Acceleration (power performance) and top speed are determined by the vehicle's specific power and final drive ratio. A higher specific power indicates better power performance, akin to a strong horse pulling a light carriage. Displacement: Displacement refers to the engine's total cylinder volume, which is the volume swept by the piston from top dead center to bottom dead center, also known as single-cylinder displacement. It depends on the cylinder bore and piston stroke. Engine displacement is the sum of the working volumes of all cylinders, usually measured in liters (L). Engine displacement is one of the most important structural parameters, as it more accurately represents the engine's size than cylinder bore or the number of cylinders. Many engine performance metrics are closely related to displacement. Maximum Torque: Maximum torque refers to the highest rotational force output by the engine's crankshaft. It typically occurs in the mid-to-low RPM range of the engine and tends to decrease as RPM increases.
