Engine is the heaviest component of the vehicle, and its position directly affect how the car drives. Engine can be placed on chassis in the three different position.
1. Front position engine
2. Rear position engine
3. under floor position engine
1.Front position engine
In the front position engine , engine is placed at the front of the engine and rear wheel drive are used. but in some of the vehicle drive is given to the front wheel only.The engine placement is remains the same in the heavy vehicle, but the cab is brought forward over the the engine to increase the pay load. The engine position at the front with rear wheel drive system require greater length of the shaft.
This engine position gives the protection to the driver when the head collision happen as the mass of the engine is greater than the any other parts of the vehicle .
In case of rear wheel drive
2. Rear position engine
In this position, the engine is mounted to close to the back axle. The propeller shaft require is reduced and usually it is used for small car.This position provides more space to the passenger cabin.
The major portion of the vehicle lies on the rear wheel and it help to in traction
up the hill. luggage is kept at the front near to the driver which some how balance the vehicle.
3.under floor position engine
This position of the engine is also called as Mid position engine. in this the engine is in the center, under the chassis .basically this system is used in the public service vehicle like bus and the heavy lorry. it reduce the crankshaft length from the engine to axle. special features of this system that it eliminate the heat and noise from from the vehicle, to fix the engine problem and maintenance is easy.

In case of rear wheel drive
- The weight distribution is reasonably balanced between the front wheel and rear wheel which gives good handling support.
- Due to engine and radiator are at front the forward facing radiator take full benefits of the natural air flowing produce by the vehicle movement.
