4950cc

4950cc is a numeric designation used to express engine displacement in cubic centimeters. The “cc” stands for cubic centimeters, a unit of volume in the metric system. 4950 cubic centimeters equals 4.95 liters (since 1 liter = 1000 cubic centimeters). In engine specifications, the displacement represents the total swept volume of all cylinders in one engine cycle, so a 4950cc engine has a combined displacement of 4.95 liters. In U.S. customary units, this is approximately 302 cubic inches.

Usage and context: The figure is commonly found in automotive engines, motorcycle engines, and some light aircraft engines. Engines in the 4.5–5.0 liter range are often described in marketing as 4.9 or 5.0 L; the exact value may be rounded or presented differently by manufacturers. Displacement is a key specification that can influence performance characteristics such as peak torque and potential power, but it does not directly indicate overall efficiency or driver experience.

Measurement and interpretation: Displacement is calculated from the bore and stroke of each cylinder and the number of cylinders. The stated 4950cc is a nominal figure and may reflect rounding or measurement conventions used by different manufacturers. While related to size and potential output, displacement alone does not determine actual engine performance, which also depends on factors like aypowertrain design, tuning, and drivetrain efficiency.
