This stands for ‘antilock brake system’. It was introduced in the year 1985 as a safety feature to give drivers more control when braking. The ABS system uses sensors to monitor the breaks to prevent skidding during panic stops or when braking hard on a wet or slippery surface.

7. Oversteer:
This occurs when you are cornering. If your rear tires start to lose traction before your front tires do, your car will experience oversteer. This will cause the back end of the car to step out, and you will start to go sideways.

8. Understeer:
This is the opposite of oversteer. When cornering and your front tires start to lose traction before your rear tires do. When this happens, the front of your car will refuse to turn the way you want it to; the rear will still be gripping the road.

9. Pound-foot (pound-feet):
This is used as a measure for torque. Abbreviated as lb.-ft

10. Throttle blip:
Applying a short stab of the throttle in order to raise your engine revs.

11: Drivetrain:
The drivetrain is the part of a vehicle which transfers the engine power to the wheels. It consists of Transmission, Propeller shaft, axles etc. Depending on the vehicle’s design, engine power is transmitted by the transmission to the front wheels, the rear wheels, or to all four wheels.
The wheels receiving power are called drive wheels: They propel the vehicle forward or backward. Most automobiles either are front-wheel or rear-wheel drive. In some vehicles, four-wheel drive is an option the driver selects for certain road conditions; others feature full-time, all-wheel drive.

12. FWD:
Stands for front-wheel drive. This is a type of drivetrain where power to propel the car are all transmitted to the front wheels.

13. RWD:
This stands for rare-wheel drive. This type of drivetrain sends all the power needed for propelling the vehicle to the rear wheels.

14. AWD:
Vehicles equipped with all-wheel drive transmit power to all four wheels at all time.

15. 4WD:
It stands for four-wheel drive.
A 4WD system is almost the same with the AWD, but it is more rugged. A 4WD system can be part-time or full-time. The driver selects the mode the car will operate on (part-time). It is full time when the driver has no control over it.
