The engine...
sports cars are faster than an economy car so they think you will speed and that makes you more likely to get in an accident
The car in the picture is a Bugatti Veryron. Top speed = 254.04 mph
This question makes no sense, what do you mean? the speed of the car does not dictate the posted speed limit.
Gearing down increases the engine's revolutions per minute (RPM) and torque, but decreases the speed of the car. This allows the engine to work at a more efficient RPM range for the desired speed or acceleration.
Being a hybrid or fully electric car makes a car quite efficient. Also a lot of factors determine how much fuel effienciency a car has. Such as weight, tire pressure and speed.
the fatter you are, the less speed your car will max out at, but, the more weight, the more momentum
"Motor cars are a lot more powerful in terms of speed and fuel life. However, a hybrid car's battery is electrical which makes the car life regenerative."
Streamlining reduces air resistance or drag on the car, allowing it to move more efficiently through the air. As a result, less energy is required to maintain a certain speed, enabling the car to reach higher speeds more easily.
I have car speed is more
The more you push on the accelerator the more you increase the fuel/air mixture to the engine which will cause the engine to turn more RPMs, thus propelling the vehicle at a faster speed.
Chart? There is no chart. Your question makes no sense.
What do you mean by that question? There are a lot of things that change speed in a car. When more air and fuel enter the cylinders on a motor, it makes it speed up. When the motor speeds up, it makes the transmission spin faster, and when you shift gears it makes the driveshaft spin faster, along with the gears in the rearend, unless you have a front wheel drive car, then it makes the wheels spin faster. When the motor speeds up, the accessories driven by the belt or belts on the front of the motor spin faster. when the wheels spin faster, the car goes faster.
