In general, a larger engine displacement like 4.2 liters indicates that the engine has a greater capacity and can produce more power and torque compared to smaller displacement engines. However, the overall output and performance of an engine also depend on various other factors such as engine design, fuel efficiency, induction system, and engineering optimizations.
The size of an engine is an essential specification in understanding its characteristics and potential performance. Larger engines, such as a 4.2 liter, are often found in trucks, SUVs, sports cars, and high-performance vehicles where a higher power output is needed.
