BASIC TERMINOLOGIES

BORE AND STROKE:
       Bore and stroke refer to the dimensions of the engine's cylinders. Bore is the diameter of a cylinder, stroke is the distance the piston travels inside the cylinder.


RPM:
       RPM stands for "REVOLUTION PER MINUTE".The number of revolutions made per minute by the fly wheel is called RPM.


TORQUE:
               Torque is a twisting force. It is the power output of an engine at one specific point in time.

For eg. 200@400.The 200 stands for torque and 400 stands for RPM.i.e the engine acquires a torque of 200NM at 400 RPM.The above is just an example we dont get a torque of 200 at 400 RPM.

                *Torque is for acceleration.Torque at a low rpm is good because you get fast acceleration .

HORSE POWER:

                        It is basically denoted as HP.HP is for speed.Horsepower is the abiltiy to do work over a period of time. Other things are taken into account, but it is based on torque so the two will follow each other to some degree. Torque comes on first because it is the instant twisting force. Horsepower is built as you get going and things like momentum of engine components come into play. 

DRIVE TRAIN:

                   The drive train is the system that transfers the energy from the engine, to the axle to turn the wheels.

You may find some cars with option "BASE AND S".

                   Where S-Sport transmission

                       BASE-Basic transmission.
