Automobile or aeronautical engineering

The roots of aeronautical engineering can be traced to the early days of mechanical engineering, to inventors’ concepts, and to the initial studies of aerodynamics, a branch of theoretical physics

The earliest sketches of flight vehicles were drawn by Leonardo da Vinci, who suggested two ideas for sustentation

If you're interested in automobile designing, modelling and you interest in High speed racing car models, well you could go for automobile engineering

If you call out for the design, mechanics and principles of how and what of an aircraft, then aeronautical is your choice
