Two systems both can send power to the front and rear wheels. System A is meant to stay on all the time, even on dry pavement, and it automatically adjusts how much power goes to each end. System B is a switchable mode mainly for loose/slippery surfaces; when switched on it forces the front and rear to rotate together, and it can feel “bindy” on dry pavement. Which is the best match?

About this course

Explore how modern passenger cars work as integrated systems, from the engine to the taillights, using clear, low-math explanations. The focus spans the internal combustion engine, its support systems, and how power flows through the drivetrain to the wheels. It covers steering, suspension, braking, and the fundamentals of automotive electrical and electronic systems including ECUs, sensors, and vehicle networks. Safety, comfort, and driver-assist systems are introduced conceptually, along with practical maintenance basics and simple diagnostic approaches for real-world understanding.
