Throttle response or vehicle responsiveness is a measure of how quickly a vehicle's prime mover (usually an internal combustion engine) can increase its power output in response to a sudden press of the accelerator pedal or similar input. Throttles are not used in diesel engines, but the term throttle is often used to refer to any input that modulates the power output of a vehicle's prime mover. Throttle response is often confused with better power, but throttle response is rather related to time taken for change in power level.[1]
Generally gasoline/petrol engines exhibit better throttle response over diesel engines. Also naturally aspirated gasoline engines have better responsiveness over supercharged and turbocharged engines. Here comparison should be experienced in engines which have same peak power output. Several tuning factors have an effect upon the responsiveness of the throttled engine.[2][3]
Throttle response in manual cars can be enhanced by dropping to a lower gear (e.g. 5th to 4th) just before an overtaking maneuver and is often utilised in smaller cars to aid in overtaking maneuvers
Most new cars are equipped with a drive-by-wire system. Throttle response is often affected badly by this and drivers feel a noticeable delay when quickly changing the position of the gas pedal.[citation needed]
Application of throttle response
Throttle response comes into play in the following:
- Overtaking
After following a vehicle or going side by side, there is a need for sudden increase in power to execute a successful overtaking. This is why throttle response plays a crucial role in racing.
- Coming out of a corner
While entering a corner, brake is applied or at least power is reduced. As soon as the corner is passed, the car should be accelerated quickly. Better throttle response gives a sudden surge in power.
- Driving pleasure
Throttle response plays a major role in driving pleasure, as this gives the driver more control over the vehicle's acceleration.
