In the N/V parameter, V stands for which?

• A. Vehicle speed
• B. Normal velocity
• C. Valve position
• D. Voltage

Answer: (A)

V stands for vehicle speed—the rate at which the car is moving. In the N/V pairing, N usually represents the engine’s rotational speed (RPM), so the N/V relationship shows how fast the engine is turning relative to how fast the vehicle is traveling. This helps with understanding gearing, transmission behavior, and when to target certain shift points during tuning. The other options don’t fit because normal velocity isn’t a standard term used here, valve position refers to a valve mechanism rather than vehicle motion, and voltage is an electrical quantity, not a measure of the car’s motion.
