Types of automobile drives
1. Front engine rear wheel drive
2. Front engine front wheel drive
3. Rear engine rear wheel drive
4. Four wheel drive



Front engine rear wheel drive:
We know engine produces power and the produced power will be transmitted to the wheels through the different components of transmission system such as clutch, gear box, propeller shaft, axes, etc. In this type of drive the engine is mounted on the front side of the vehicle and the power is given to the rear wheels.
Advantages:
> As the engine is mounted on the front side and the passenger will seat at the backside so that proper weight distribution is possible.
> In this type of vehicles we can have luggage space at the backside.
> As the engine is very close to the driver, the linkages of clutch and gearbox are very short and simple.
> We can take full benefit of air cooling to cool the engine with the help of radiator.
Disadvantages:
> As the propeller shaft is required for power transmission, ground clearance of this type of vehicle may increase.
> Due to long power transmission system, the weight of vehicle increases.
> Because of propeller shaft some projections may come out to the passenger cabin which results in decreased interior space of the vehicle.

Front engine front wheel drive:
In this case the power produced by the engine is given to the front axles. The rear axles are dead which means no power supply to the rear wheels at all.
Advantages:
> Due to the absence of propeller shaft, maximum space will be available for the passenger.
> As the transmission system is not so long and less components are required for power transmission, the weight of vehicle decreases.
> As the engine is mounted on the front side and the passenger will seat at the backside so that proper weight distribution is possible.
> We can take full benefit of air cooling to cool the engine with the help of radiator.
Disadvantages:
> In case of hill climbing, more tractive efforts are required at the backside of the vehicle as compared to the rear engine rear wheel.
> As the drive is given to the front axles and steering system is mounted on the same axle, design of vehicle becomes more complicated.
> Because of this complication for steering system the space available may be less. So turning radius of these vehicles is less than the rear wheel drive.

Rear engine rear wheel drive:
The engine is mounted at the rear side of the vehicle and the power produces by the engine is given to the rear axles.
Advantages:
> Due to absence of propeller shaft there is no obstruction for floor space.
> In this type of drive due to engine position and weight of the vehicle, tractive efforts required will be less. This gives better road grip on hills.
> As whole system is at rear side only one oil sump is required for lubrication of engine and gearbox.
Disadvantages:
> To operate clutch and gearbox, long linkages are required.
> As the engine is mounted at the rear side, air cooling is not possible.
> Engine is at the rear side and the passenger will seat on rear side. This makes weight distribution of vehicle uneven.

Four wheel drive:
In this type of drive only one extra unit is added named as transfer box. The main function of transfer box is supply power to the four wheels or two wheels according to the requirement of drive.
Advantages:
> As power is supplied to the four wheels, the whole weight of the vehicle is available for traction.
> This type of vehicles can travel on rough as well as uneven roads.
> If one side of the vehicle is ditches, they can be easily removed off.
Disadvantages:
> Because of transfer box, initial and running cost is high.
> Extra transfer box is needed for this type of drive.

Difference between four-wheel drive and all-wheel drive:
We know in 4-wheel drive we have an option to supply power to either two wheels or four wheels. But in case of all wheel drive, power produced by engine is supplied to all wheels. In such cases we don?t have any option to supply the power to only two wheels.
