- Throttle response
Throttle response or vehicle responsiveness is the responsiveness of the vehicle to
throttle (accelerator pedal) modulation. When accelerator pedal pressed suddenly, how fast power output of engine increases implies the throttle response of that vehicle. Throttle is not used in diesel engine, but the term throttle often refers to accelerator control. Throttle response is often confused with better power, but throttle response is rather related to time taken for change in power level.

Also naturally aspirated petrol 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 throttleed engine.

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.Application of throttle response
Throttle response comes into play in the following:;Overtaking:After following a vehicle or going side by side, there is need for sudden need of power to execute a successful
overtaking . So throttle response plays crucial role inracing .;Coming out of a corner:while entering acorner brake is applied or at least power is reduced. As soon as a corner is over car should be accelerated quickly. Better throttle response gives sudden surge in power.;Driving pleasure:Throttle response plays major roledriving pleasure , as this gives the driver more control on vehicle's acceleration.See also
