Question Make vehicle with wheel colliders accelerate faster

I have vehicle using wheel colliders using default settings and to accelerate I apply motor torque to front wheel. Despite how high motorTorque value is applied, vehicle accelerates slowly. But with higher value car keeps accelerating for a longer time even when acceleration key is released. My question is what can I do to make car accelerate faster and start deccelerating as soon as acceleration key is released?

P.S. I can't add code or images to my post
