Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the mechanical function?Splits and distributes engine power from the transmission to multiple drive axles
2. What is the system integration?A core component of 4WD and AWD vehicle drivetrains
3. What is a transfer case and where does it go in a car?The transfer case is a box inside the drivetrain that takes power from the transmission and sends it to the front and rear axles. It helps trucks and cars drive in mud, snow, or tough off‑road trails.
4. Why do trucks have a low‑range gear in the transfer case?The low‑range gear, called 4‑Low, multiplies the engine’s torque so the vehicle can crawl over big obstacles, climb steep hills, or pull heavy loads without stalling.

Drivetrain: The integrated system of components that transmit engine power to the vehicle's wheels.
Torque Multiplication: Increasing the rotational force delivered to the wheels, typically for low-speed, high-traction situations.
Driveshaft: A rotating shaft that transmits mechanical power from one component to another, often between the transfer case and axles.
