Vehicle Fundamentals

Layout, structure and the physics every vehicle obeys. How a vehicle is put together and how it behaves: architecture and layouts, vehicle dynamics, chassis, body and powertrain — the foundation for every other automotive subject.

• Vehicle Architecture — Vehicle architecture is the big-picture layout of a car: where the powertrain, driven wheels, occupants, battery and electronics go. Learn body styles, drivetrain layouts (FF, FR, MR, RR, AWD), platforms and modularity, weight distribution and centre of gravity, packaging, and electrical/electronic (E/E) architecture.
• Vehicle Dynamics — Vehicle dynamics explains how cars accelerate, brake and corner. Learn tyre forces and slip, longitudinal performance limits, cornering and lateral load transfer, understeer and oversteer, the understeer gradient and characteristic speed, rollover threshold and stability control.
• Chassis — The chassis is the vehicle's load-carrying skeleton. Learn ladder frames, monocoques (unibody), space frames and skateboards, load cases (bending, torsion, braking, cornering, bumps), torsional stiffness, frame stress calculations, and modern materials and joining.
• Body — The body protects occupants, shapes airflow and defines the car's look. Learn body-in-white (BIW), closures and trim, crashworthiness (crumple zones, safety cage), aerodynamics (drag, lift), materials and lightweighting, and corrosion and NVH.
• Powertrain — The powertrain makes and delivers tractive power: engine or motor, transmission, driveshafts and differential. Learn ICE, hybrid and electric powertrains, tractive effort vs road load, gear matching, acceleration and top-speed estimation, and efficiency from tank/battery to wheels.
