An automotive engineer designs, analyzes, tests and improves vehicle systems such as structure, powertrain, brakes, steering, batteries and software controls. Most people in the role hold a bachelor's degree in mechanical, electrical or automotive engineering, so this roadmap builds that foundation with free university-level material and then moves you into real projects. You start with the physics and math that every vehicle obeys. Then you learn CAD, simulation, testing and root cause analysis, the daily work of the job. Last, you specialize in a high-demand area such as EV powertrain, vehic

Stage 1 of 3 · about 16 weeks
Understand the physics, math and mechanical basics behind every vehicle system, and make your first CAD parts.
Statics, dynamics and mechanics of materials
Every vehicle part must carry loads without breaking and without being too heavy. Statics tells you the forces, and mechanics of materials tells you whether a part survives them. Without this, CAD is just drawing.
Calculus, linear algebra and differential equations
Vehicle motion, vibration and control systems are all described by equations. If you can read them, you can predict how a suspension or a motor will behave before you build it.
Thermodynamics and engine and powertrain basics
Engines, hybrids and battery cooling all depend on energy conversion. Knowing the Otto cycle and efficiency tells you why a design wastes energy as heat.
3D CAD modeling and drawings
CAD is how designs are communicated and manufactured. O*NET lists SolidWorks, CATIA and AutoCAD as core tools. Learning one well makes the others easy to pick up.
Programming basics in Python and C
Modern vehicles run on software, and you will analyze test data and sometimes write control code. Python handles data fast, and C is the language of embedded ECUs.
Then 2 more stages (about 60 weeks in all) with lessons, drills, projects, 6 interview questions with strong answers and free resources.
