New vehicles do not use a throttle cable they use an electronic gas pedal that sends a message to the computer that sends a message to the rest of the vehicle. There is a delay between stepping on the pedal and acceleration. Could be that. Or, you didn't mention if there was a turbo charger involved. There is a thing called turbo lag. From the time you hit the pedal to the time the turbo spins up creates a lag. Could be that. Or, it could be both.
^^^^ This.
It's called smoothing. Some cars and trucks have more and some have less. If you're talking used you can get a programmer and make it as harsh or smooth as you want.
New FI engines have REALLY good throttle input. That being so, the manufactures don't want just a tap at a stop sign to torch the tires so they smooth the program out.
To get the best performance out of my truck I have to "roll on" the throttle not punch it. It takes getting use to and I still don't like it after 8 years.
