What is a drivetrain & Powertrain?
Simply put, a drivetrain is the series of parts in your car that work together to make your wheels turn. A powertrain, on the other hand, is basically a drivetrain plus the engine and some other parts,

Types of Drivetrains:
The four different types of drivetrains are
1) Front-Wheel Drive (FWD)
2) Rear Wheel Drive (RWD)
3) 4 Wheel Drive (4WD)
4) All Wheel Drive (AWD)

1) Front-Wheel Drive (FWD):
Front-wheel drive refers to a car in which the transmission sends the engine’s power to the front wheels. Rear-wheel drive is the transmission that sends the engine’s power to the rear wheels. Four-and all-wheel drive cars have power at all four corners.

If a vehicle features front-wheel drive, the transmission transfers power from the engine to the front wheels. The majority of cars today have a front-wheel-drive layout. This setup transfers power to the front wheels, giving them the responsibility of moving and steering the vehicle.

2) Rear Wheel Drive (RWD):
Rear-wheel drive is basically the opposite of FRONT wheel drive. This drive is most commonly found on sports cars and performance sedans. Vehicles that feature rear-wheel drive are a bit more complicated.
Vehicles handle much better than front-wheel drive vehicles and you will notice the difference in curves, turns, and when navigating through traffic situations.

Traction won’t be as good, especially in wet or snowy road conditions. A rear-wheel-drive car of the same weight, power, gearing, and tire size and type will accelerate faster than a Front wheel drive car, as the weight of the vehicle is transferred off the front wheels and onto the rear wheels to improve traction. Front-wheel drive cars typically lose traction in these situations.

3) 4 Wheel Drive (4WD):
Four-wheel drive, often abbreviated as 4WD, 4WD means the power from the engine is delivered to all 4 wheels all of the time when Four-by-Fours(4x4) is engaged, The 4WD vehicles are usually equipped with a transfer case which allows the car to change to RWD transmission in order to save fuel and get back to 4WD mode if and when required.

4WD-equipped cars are called Four-by-Fours (4x4s) as the first digit here represents the number of wheels, and the second figure shows the total number of powered wheels. For example, trucks with 6×4 configurations have 6 wheels, out of which only 4 receive power. Most off-road-ready SUVs come with the 4WD system as they offer more traction.

4) All Wheel Drive (AWD):
An all-wheel-drive arrangement works on pretty much the same principle as 4WD, but in most front-wheel drive or rear-wheel drive as the primary drive mode. The general misconception is that AWD and 4×4 are the same things. While both of them have all 4 wheels running, and they run on the same principles, there are some key differences that set the two apart.

While most of the 4×4 send power to the rear wheels if and when required, the AWD cars are mostly FWD or RWD, depending upon the situation. This drive train employs a front, rear, and center differential to provide power to all four wheels of a vehicle.
How differential work
The differential is a device that splits the engine torque two ways, allowing each output to spin at a different speed. The differential is found on all modern cars and trucks, and also in many all-wheel-drive (full-time four-wheel-drive) vehicles. These all-wheel-drive vehicles need a differential between each set of drive wheels, and they need one between the front and the back wheels as well, because the front wheels travel a different distance through a turn than the rear wheels.

How to Transfer case Work
On a four-wheel or all-wheel drive (AWD) vehicle, it directs power to two or four wheels. When the transfer case engages the front shaft, which feeds power to the front wheels, the vehicle then becomes a four-wheel drive. All-wheel drive vehicles receive power through the transfer case at all times.
