| accelerate |
An action by pressing the accelerator/gas pedal to get the car moving away. |
| accelerator |
Refers to the gas pedal, which u places your right foot and step on it to gain speed of a car. |
| Aerodynamic |
A shape design of the external body parts to allow the wind to bypass efficiently through the moving car. If the design is aerodynamic enough, it will not only reduce the wind drag to increase fuel economy, but also will increase the grip of that car gradually in fast speed. |
| air filter |
A filter placed at the air induction inlet to filter off unwanted dirt and particles to prevent them to get into the engine and shorten the engine life. |
| airbag |
It is a security feature that is mounted into most of the car nowadays. As its name describe, it is a bag which will pop up very instantly when an emergency happens. The bags contain rich air preventing the driver or passenger to knock against panel in the car. |

| automatic transmission |
A type of transmission that automatically changes the gear when your car is at different speed. This is used on most of the road cars nowadays due to its convenient feature. This type of transmission are easy to operate but it do not have the power like the manual transmission provide. |
