What is the horsepower rating and engine speed?

• A. 100 BHP at 2,400 RPM
• B. 120 BHP at 2,600 RPM
• C. 95 BHP at 2,300 RPM
• D. 110 Rated BHP at 2,550 RPM

Answer: (D)

The horsepower rating is the official, continuous power the engine is designed to deliver at its rated speed. The rpm shown is the speed at which that rating applies. In engine specifications, the rating is usually labeled as “Rated BHP” to distinguish it from peak or transient outputs. The correct choice uses that standard designation and gives the exact rpm—110 Rated BHP at 2,550 RPM—matching how engines are specified. Other options pair a power figure with different speeds or omit the “Rated” qualifier, which makes them inconsistent with how the engine’s official output is defined.
