first lets just focus on power. the key component
in order to accelerate that fast with a car, you would need a horsepower amount so high it is litterally unfathomable.
the worlds fastest jet cars are reaching just on the border of the speed of sound. to put that into perspective, it has 2 (I believe) sr-71 blackbird engines. ( I am asuming you know a little about planes, the berkut aircraft are not mentioned that often)
next, wheels and tires. the wheels have to be machined from solid billet chunks of aluminum so precisley that if not done properly will literally, and I mean litteraly explode at those speeds. tires would also melt.
at that rate of acceleration and speed, body work would rip off and destroy itself.
in the game, the car acclerates the faster it goes, and only stops due to hitting the wall. the car itself is capable of so much more!!!
hope that answers most of those questions.
