Understand engine displacement in Gran Turismo 3: A-Spec. Learn how cubic space, RPMs, and power are connected.
Displacement is the cubic space of the cylinders summed together. For example, a car with a 3.0L (Liter) inline 6-cylinder engine has a displacement of 0.5L per cylinder. Generally, the more cubic centimeters (cc), cubic inches (ci), or liters (L) an engine displaces, the more air/fuel mixture it can consume during each power stroke. Note that 3000cc is equivalent to 3.0L, and 1000cc equals 1L.
Displacement is directly connected to RPMs (Revolutions Per Minute). A higher displacement engine typically has lower maximum RPMs due to increased reciprocating (rotating) mass. For instance, a C5 Corvette with a 5.7L (346 ci, or 5700cc) engine makes around 350 horsepower and maxes out at approximately 6500-6750 RPMs. In contrast, an F1 car uses a smaller, naturally aspirated 3.0L engine but achieves 800-900 hp by reaching RPMs up to 18000. This illustrates a trade-off between displacement and RPMs.
- Increasing displacement effectively increases the engine's size, leading to a more powerful engine.
- There is a trade-off between engine displacement and its maximum RPMs.
