The document describes the different layouts of automobiles, including where the engine and drive wheels are located. It discusses the main types - front engine rear wheel drive, rear engine rear wheel drive, and front engine front wheel drive. For each type, it provides details on their characteristics such as noise isolation, drive train loss, weight distribution, and handling. The document aims to explain the different configurations and their respective advantages and limitations.

1. Layout of Automobile

2. It describes where on the vehicle the engine and drive wheels are found

3. Layouts of Automobile
• Rear Wheel Drive Layouts
• Front Engine Rear Wheel Drive
• Rear Engine Rear Wheel Drive
• Front Wheel Drive Layouts
• Front Engine Front Wheel Drive
• Rear Engine Front Wheel Drive

4. Front Engine Rear Wheel Drive
•Conventional type of layout
•Well suited for load carriers
•Has drive-train loss

5. Rear Engine Rear Wheel Drive
•Engine noise is isolated from the passenger compartment
•Reduced drive train loss by using transaxle
•Engine control links should be extended
•Greater rear weight bias
•Better traction but, rear weight transfer increases on
acceleration
•Better braking
•Tends to oversteer (when decelerating)

6. Front Engine Front Wheel Drive
•Most popular layout used in recent cars

7. Advantages
• Economic
• Vehicle has good adhesion on road as more weight is
placed on the front wheel
• Has better road holding even on curves and slippery road
• compact packaging
• No need of central tunnel through passenger
comp.
• Engine can be mounted transversely
(hasTransaxle)
Limitations
• Not used in powerful cars as it's difficult to feed more
power and increase speed during a turn without resulting
in understeer

8. Rear Engine Front Wheel Drive

9. All Wheel Drive (AWD)
• Has more drive-train loss
• Understeer can result
• However now its combated with trick and techy differentials and
electronics to stay virtually as RWD for a few moments
(sometimes 3WD too)
